1 The Company and the Product INDUSTRIA LOMBARDA MATERIALE ELETTRICO SpA has been operatng n Mlan snce 1938, n partcular n the electrotechncal sector for the manufacturng of equpment for ndustral nstallatons. ILME reflects the tradtonal entrepreneural sprt of Lombardy, and has enjoyed contnuous expanson for over half a century. The company has carved an mportant role for tself n the man world markets, also operatng drectly n the countres that have assumed world leadershp n the feld of automaton, ncludng Germany and Japan. In the electrcal connecton sector wth applcatons n ndustral automaton, charactersed by top performance and utmost relablty needs, ILME s today the acknowledged partner of many leadng companes worldwde. The company s fundamental values are: product nnovaton, orgnal solutons, excellent prce-qualty rato, a customer-orented sense of servce, ethcal behavour and an envronmentally-frendly approach. CE markng As from 1 January 1997, n order to launch electrcal products on the European market the manufacturer must ensure these bear the relevant CE markng, n lne wth the Low Voltage Drectve 73/23/EEC * (mplemented n Italy as law no. 791) and ts modfcaton 93/68/EEC * (mplemented n Italy as L. D no. 626/96, publshed n the supplement to the Gazzetta Uffcale of ). Sad markng must be placed on the product - or, f ths s not possble, on the packagng, the nstructons for use or the warranty certfcate - and acts as a declaraton by the manufacturer that the product comples wth all relevant EU drectves. ILME products bear the CE markng on the product or packagng. Almost all ILME products fall under the Low Voltage Drectve. A declaraton of complance s requred before applyng the CE markng. Ths document, to whch the market s not drectly enttled, must be made avalable to the control authortes (n Italy the Mnstry for Industry, Commerce and Handcraft) at all tmes. In t, the manufacturer declares the techncal safety standard(s) followed to manufacture the product. These standards must be, n decreasng order of preference: - a European standard (EN prefx) - a European harmonsaton document (HD prefx) - an nternatonal IEC standard - a natonal standard - n the absence of reference standards, the manufacturer s nternal specfcatons, guaranteeng complance wth the drectve s basc safety requrements. Complance wth harmonsed techncal standards (.e. ratfed by the CENELEC) consttutes presumed conformty to the drectve s basc safety requrements. The CE markng of ILME products results from sad products declaraton of conformty to harmonsed standards or nternatonal IEC standards. Through the CE markng, ILME declares full complance, not merely wth the drectve s basc safety requrements, but also wth those nternatonal or natonal EU standards on whch voluntary safety certfcaton markngs are based (e.g. IMQ and VDE). In ths way, ILME ntends to award the CE markng the value of self-certfcaton n terms of safety, gven the loss n legal value of voluntary certfcatons ssued by thrd partes, ratfed by drectve 93/68/EEC *. Notwthstandng the above, practcally all ILME products stll bear voluntary conformty markngs. To promote the contnung mprovement of ts qualtatve results, ILME has always encouraged ts collaborators to work wth utmost responsblty and partcpaton. The company focuses on a seres of benefts to the user, ncludng research nto the most sutable materals, hgh qualty and safe cablng, a rapd turnaround and readly avalable servces. Ths EC declaraton of conformty becomes null and vod when the assembly of products ncludes one or more components not manufactured by us and wthout EC approval. * Note: new legal reference for the Low Voltage Drectve s 2006/95/EC whch s the consoldated edton of Drectve 73/23/EEC + Drectve 93/68/EEC. On March 29, 2014, the new Low Voltage drectve 2014/35/EU has been publshed on the Offcal Journal of the European Unon, as a recast of the prevous drectve 2006/95/EC.

7 IMPORTANT NOTES ILME desgns and manufactures complete solutons for Heavy Duty electrcal power connectons. The connector (although offered to the user as a varety of elements, usually nserts and enclosures, to allow the selecton of the deal combnaton) has been desgned as a sngle part and tested to be complant wth the essental safety requrements of the EU Low Voltage Drectve 2006/95/EC and n partcular the EN standard. The desgn of ths modular system guarantees that every approved combnaton of nserts, enclosures and accessores cannot result as mproper. The products n ths catalogue alone cannot guarantee the best functonalty upon nstallaton, as ths depends also on ther correct nstallaton nto servce whch must be performed n complance wth the applcable system safety standards and accordng to the rule of the art. Therefore the effectveness of the nstallaton of the connector depends on the choces of the end user who must also take nto account the followng safety requrements. Connectors must not be connected or dsconnected when lve or under load. After wrng the nserts t s necessary to verfy the contnuty of the protectve earth connectons. The correct couplng of the nserts s guaranteed only f they are nstalled (wth the four fxng screws suppled) nsde the correspondng enclosures or onto compatble accessores n ths catalogue. I.L.M.E. SpA s not responsble for any dfferent applcaton. Wrng of screw-type termnal connectons must be carred out applyng the correct tghtenng torque n order to avod false contacts or damage to the conductor, the screw or the termnal. Crmpng tools and contacts used should preferably be suppled by the same manufacturer to avod dffcultes wth the nserton and retenton of the contacts themselves. Correct wrng of sprng-clamp connecton nserts s guaranteed only when the correct screwdrver ndcated n the specfc catalogue, or possbly on the nsert, s used. Avod forcng the contacts durng connecton and dsconnecton. Connectors must be coupled and uncoupled n the axal drecton wth respect to the contacts, wthout bendng and pullng the attached conductor bundles or cables. Installaton of two nserts sde by sde, n enclosures wth two bays, must respect the polarty drawng marked on the nsert (or the contact-sde vew, as shown n ths catalogue) to avod nverted couplng. The nstallaton of two or more dentcal connectors sde by sde s recommended only wth the use of codng pns n order to avod msmatched couplngs. In order to keep the declared degree of protecton (IP code), enclosures must be completed wth cable glands and/or other accessores wth at least an equal protecton ratng. Moreover, the IP protecton ratng (accordng to EN 60529) s guaranteed when the enclosures, complete wth nserts, are coupled and locked wth ther lockng levers (or devces). Fnally, Please note: - ILME cannot be held responsble for ndvdual components n uses other than those descrbed n ths catalogue. - ILME cannot be held responsble for ncorrect connector selecton n relaton to the envronmental condtons of the applcaton (e.g.: nfluence of ambent temperature, mosture, envronmental polluton, etc.). Connector nserts and ther enclosures are generally compatble wth smlar/equvalent products from other manufacturers, accordng to the last samples tested. Full compatblty cannot be guaranteed n the event of techncal changes made by other manufacturers. In partcular, maxmum performance of IP68 enclosures (Seres CG) cannot be guaranteed when coupled wth other manufacturers products. I.L.M.E. SpA takes no responsblty n verfyng whether the components heren contaned comply wth any specfc regulatons of felds of applcaton. 6

11 techncal features - enclosures Multple versons of enclosures are avalable, made n de cast alumnum alloy wth an oven-baked coatng of epoxy-polyester powder or n self-extngushng thermoplastc materal. They are resstant to mpact and strong mechancal stress. The couplng stablty and protecton aganst accdental openng are assured by sngle or double closng devces comprsng levers, sprngs and pegs n galvansed steel or entrely n plastc. Sealng s assured by specal gaskets that protect the contact groups nsde the enclosures aganst dust and aggressve agents. In general, the coupled enclosures wth the approprate user-selected connectons guarantee IP44, IP65, IP66 and IP67 (IEC EN 60529) protecton ratng. The enclosures n de cast alumnum alloy are made of n the versons: - JEI -P wth 1 and 2 levers n thermoplastc materal - JEI -V wth 1 lever n galvanzed steel - JEI -V wth 1 lever n galvanzed steel and plastc cover - JEI -V wth 2 levers n galvanzed steel It s also possble to use the JEI nserts n combnaton wth the T-TYPE enclosures: the seres of enclosures made entrely of self- extngushng thermoplastc materal. The combnaton of JEI nserts and T-TYPE enclosures extends the feld of applcaton of ths seres to envronments where powder pant s dscouraged. Most of the enclosure versons have been certfed by UL as Recognzed Components for the USA and Canada (cul mark) and hence are sutable accessores for our set of UL and CSA certfed connector nserts (fle UL E115072, fle CSA _0_000). The certfcaton has been acheved by successfully completng several tests carred out n complance wth standard ANSI/UL 50 (Enclosures for Electrcal Equpment) whch s equvalent to the North Amercan voluntary standard NEMA 250 (NEMA = Natonal Electrcal Manufactures Assocaton) and to the equvalent Canadan standard CSA C22.2 No.94 (Specal Purpose Enclosures) for the protecton ratngs used n North Amerca and requred by the local nstallaton codes (e.g.: NFPA 70 Natonal Electrcal Code n the US, CSA system standards for Canada); more specfcally: Type 12 (= NEMA 12): for nternal use, smlar to IP54 protecton ratng accordng to IEC/EN 60529; Type 4 (= NEMA 4): for nternal and external use, smlar to IP66; Type 4X (= NEMA 4X): for nternal and external use, as Type 4 + corroson resstance, smlar to IP66 protecton ratng. 10

15 standards Dmensonng of clearances and creepage dstances European standard EN ( ) was recently publshed for safety prescrptons for multpole connectors for ndustral uses and for the relevant tests whch ncorporates wthout modfcaton the correspondng nternatonal standard IEC Ed EN 2.0 ( ). It s applcable to connectors wth rated voltage values of over 50V, and up to 1000V, and rated currents values of up to 125A per pole, for whch no dedcated standard exsts, or to whch the partcular specfcatons or the manufacturer refer as regards the safety aspects. It can be used as a gude for connectors wth rated voltage exceedng 125A per pole and those wth a rated voltage less than 50V (the latter excluded from the scope of the Low Voltage Drectve 2006/95/EC). The new edton of the EN standard also ntroduces the defnton of connector wthout breakng capacty (COC) to better dstngush ths category of products from connectors wth breakng capacty (CBC). For termnal securty and performance requrements, accordng to the connecton technque adopted, the standard now ntegrally refers to the correspondng standards (IEC/EN seres and IEC/EN seres). For determnng the mnmum through-ar and surface nsulaton dstances,.e. creepage dstances, for connectors, ths standard now refers, wthout any modfcatons to standard IEC Ed. 2.0 ( ) 1). The followng llustrates the method of standard EN 61984, wth reference to standard IEC , for determnng the mnmum nsulaton n connectors. The rated characterstcs for each ILME connector famly are provded on pages 14 and 15. As n the frst edton, the followng are now obsolete: the nsulaton group concept and the dstncton of rated voltage values nto d.c. and a.c. voltage values 220V and 380V were adapted to standardsed values 230V and 400V accordng to IEC (2) and some concepts were taken from the regulatons for LV electrcal systems of the IEC (3) seres, such as: - the overvoltage categores (I, II, III, IV), accordng to the use of the equpment (4) : these are correlated wth the transent overvoltages taken as a bass for determnng the rated mpulse wthstand voltage; - the degrees of polluton - the classfcaton of nsulatng materals accordng to ther resstance to trackng - the condtons of the electrcal feld (homogenous or npn-homogenous). Overvoltage categores (or mpulse wthstand) The overvoltage categores of a crcut or of an electrcal system are dentfed by a conventonal number (from I to IV) based on the lmt or the control of the assumed transent overvoltage values obtaned on a crcut or electrcal system and depends on the means used to reduce the overvoltages. TABLE 1 The rated mpulse wthstand voltage for equpment powered drectly from the low-voltage mans (IEC Ed ) Rated supply voltage accordng to IEC (CENELEC HD 472 S1, CEI 8-6) Voltage lne to neutral derved from nomnal voltages a.c. or d.c. Rated mpulse wthstand voltage b) Overvoltage category V V V V Threephase a) Sngle phase I II III IV / /480 } / a) The / symbol ndcates a four-wre three phase dstrbuton system (star dstrbuton). The lower value s the voltage between phase and neutral (phase voltage), whereas the hgher value s the voltage between the phases (mans voltage). Where only one value s ndcated, t refers to three-wre, three-phase systems (delta dstrbuton) and specfes the lne-to-lne value. b) Equpment wth these rated mpulse wthstand values can be used n nstallatons n accordance wth standard IEC (Italan standard CEI 64-8/4 Secton 443, German DIN VDE ). Table 1 supples the rated mpulse wthstand voltage for equpment energsed drectly from the low voltage mans n functon of the rated voltage of the power supply system, the relatve voltage lne-to-neutral and the overvoltage category. Industral machnery and nstallatons wth fxed connecton to the low voltage supply system and consequently the relatve components ncludng multpole connectors, consttute an example of the equpment that belongs to the overvoltage category III. Examples of general equpment that comes under overvoltage category II are electrcal household applances, portable tools and other household equpment or smlar. For dstrbuton networks wth rated voltage of 230/400V (star dstrbuton wth earthed neutral), and over-voltage category III (category III: mpulse wthstandng), the demanded rated mpulse wthstandng voltage s 4kV. For dstrbuton networks wth rated voltage of 400 or 500V (star dstrbuton wthout neutral or wth nsulated neutral, or delta dstrbuton, nsulated or corner-earthed), and over-voltage category III (category III: mpulse wthstandng), the demanded rated mpulse wthstandng voltage s 6kV. Polluton degree Polluton ndcates the presence of any knd of foregn matter, whether sold, lqud or gaseous (onsed gas) that can have a negatve nfluence on the delectrc strength or on the surface resstvty of the nsulatng materal. The standard establshes four degrees of polluton. The categores are dentfed by conventonal numbers based on the quantty of pollutng agents or on the frequency of the phenomenon whch determnes the reducton of the delectrc strength and/or of the surface resstvty. Polluton degree 1 No polluton or only dry, non-conductve polluton. The polluton has no nfluence. Polluton degree 2 Only non-conductve polluton except that occasonally a temporary conductvty caused by condensaton may occur. Polluton degree 3 Conductve polluton or dry, non-conductve polluton whch becomes conductve due to condensaton whch may occur. Polluton degree 4 The polluton generates persstent conductvty caused by conductve dust or by ran or snow. Polluton degree 3 s typcal of an ndustral envronment or smlar, whle polluton degree 2 s typcal of a household envronment or smlar. Standard EN permts the szng of surface nsulaton dstances of connectors nstalled n enclosures n protecton class IP54 for the degree of polluton mmedately below that of the applcaton envronment (e.g.: 2 nstead of 3). Extract from standard EN For a connector n protecton ratng IP54 or hgher, accordng to Publcaton IEC 60529, the nsulatng parts nsde the enclosure may be szed for a lower degree of polluton. Ths apples also to coupled connectors, closure of whch s ensured by the connector enclosure, and whch may be uncoupled for test and mantenance purposes only. One may therefore use connectors nstalled n enclosures or contaners n protecton ratng IP54, at the rated data referrng to degree polluton 2 n ndustral applcatons wth degree of polluton 3, f, n complance wth the standard, the couplng of the connectors s opened only occasonally for tests or mantenance. In the event of temporary or lmted duraton n uncoupled state, a closng cover s, however, necessary, guaranteeng at least protecton class IP54. However, ths does not apply to connectors whch reman uncoupled and exposed to an ndustral atmosphere for an ndefnte perod. It should be noted, however, that polluton could penetrate nsde coupled connectors, also when t comes from remote parts of the electrcal system (e.g. through conduts provdng cable entry to the connectors enclosure). Moreover, connector enclosures are usually suppled wthout cable entry devces, wth the nstaller fttng such devces accordng to need. The degree of protecton marked on the enclosures s guaranteed only for connectors coupled through the use of cable entry devces n equal or hgher IP protecton ratng and expertly nstalled. Examples of applcaton for the selecton of degree of polluton 2 for a connector - connector on an electrc motor controller, whch s uncoupled only to replace a faulty motor, also n cases where degree of polluton 3 s nstead specfed for the system; - connector on a module-constructed machne, whch s opened only for transport purposes and whch s used only for faster nstallaton and for safer puttng nto servce. One must make sure that the connector has not been polluted durng transport. To ensure ths has not occurred, protectve covers or adequate packng must be used; - connector nsde a panel n protecton ratng IP54. In ths case one may even renounce equppng the connector wth an IP54 enclosure.

16 standards Insulatng materal group Insulatng materal nfluences the determnaton of the mnmum creepage dstance. It s charactersed accordng to the damage t suffers from the concentrated release of energy durng scntllatons when a surface leakage current s nterrupted due to the dryng of the contamnated surface. The CTI (comparatve trackng ndex, ndex of resstance to surface currents) s assumed as ndex of the resstance to creep currents of the nsulatng materals n the presence of atmospherc contamnatng agents (standard IEC/EN 60112). The CTI consttutes the numerc value of the maxmum voltage at whch a materal can resst aganst 50 drops of an electrolytc test soluton wthout trackng,.e. wthout a progressve formaton of conductve paths on the surface of the sold nsulatng materal (and permanent electrc arc between the electrodes of the test equpment) due to the combned effect of electrcal stress and electrolytc contamnaton. Sold nsulatng materals are classfed nto four groups: group I 600 CTI group II 400 CTI < 600 group IIIa 175 CTI < 400 group IIIb 100 CTI < 175 The values for groups IIIa/IIIb (Tab. F.2, IEC ) are dentcal for the purpose of determnng the creepage dstance values. The nsulatng materals used to manufacture the ILME multpole connectors belong to groups IIIa / IIIb. Electrc feld condtons The nsulaton clearance s determned n Table 2 of IEC , bearng n mnd the followng nfluencng factors: - rated mpulse wthstand voltage - electrc feld condtons - alttude: the values specfed n Table 2 are vald up to m; for hgher alttudes, the correctve factors specfed n Table F.8 of IEC ; - the mcro-envronment. The shape and arrangement of the conductve parts nfluence the homogenety of the electrc feld and consequently the clearance needed to wthstand a gven voltage. The clearances n Case A (non-homogeneous feld) have the requred mpulse wthstand voltage under all condtons: clearances not less than those specfed n Table F.2 - Case A can be used rrespectve of the shape and arrangement of the conductve parts and wthout verfcaton by an mpulse wthstand test. Determnaton of clearances In accordance wth standard IEC , the followng must be dentfed to determne t: a) The rated voltage of the power supply (usually 230/400V and therefore a conventonal voltage lne-to-neutral of 300V, n star dstrbuton networks wth earthed neutral, or 400V for star networks wthout neutral, or wth nsulated neutral, or n networks wth the dstrbuton transformer s secondary wndng delta connected, nsulated or corner-earthed and, therefore, wth conventonal phase voltage of 600V); b) The overvoltage category (usually III); c) The rated mpulse wthstand voltage determned from Table 1 of IEC (usually 4 kv or 6 kv) d) The type of electrc feld to whch the parts through whch the current flows shall be subjected (worse case = nhomogenous feld) and the degree of polluton (usually 3). The standard EN requres that the creepage dstance be dmensoned accordng to IEC For dstances up to 2 mm of nsulaton, typcally to connectors for prnted crcuts, the reference can be, alternatvely, standard IEC , to be read n conjuncton wth IEC The mnmum through-ar nsulaton dstance s therefore gven by Table F.2 of IEC , accordng to the rated mpulse derved from Table B.1 of the same standard whch s part of Attachment B (nformatve) Rated voltages of power supply networks for dfferent modes of overvoltage control. Ths table s attrbutable n partcular to devces that do not provde any upstream voltage dscharge and represents, therefore the worst case and replaces Table 5 of the prevous edton of EN The rated mpulse wthstand voltage must be chosen based on the nomnal supply voltage and overvoltage category. The assgnment of connectors to a partcular overvoltage category (usually III) s effected accordng to the rules of IEC Rated voltage Voltage value assgned by the manufacturer to the connector refer to the operatng and performance characterstcs NOTE A connector may have more than one rated voltage value.

When the clearance s less than the value ndcated for Case A an mpulse wthstand voltage test certfcate s requred. Compared to the prevous edton of IEC Table F.2 s has been changed (already wth the Varant 2). In partcular, the columns referrng to degree of polluton 4 have been elmnated.

18 standards Determnaton of creepage dstances For the mnmum surface nsulaton dstance (creepage dstance),.e. the shortest dstance along the surface of the nsulaton materal between two conductng parts (IEC defnton 3.3) standard IEC 61984:2009 for connectors refers to that prescrbed by standard IEC :2007 n Table F.4. It s determned accordng to rated voltage, degree of polluton and nsulatng materal group. The rated voltage provdng access to Table 6 (ratonalsed voltage of the power supply system) s determned by Table 3a of IEC for sngle phase two or three wre a.c. or d.c. systems or Table 3b for three-phase three or four wre a.c. systems. Usually for three-phase systems wth 230V/400V rated voltage, the conventonal lne-to-lne nsulaton voltage s 400V and the lne-to-earth for TT or TN systems s 250V. For three-phase systems wth 400V or 500V rated voltage the conventonal lne-to-lne nsulaton voltage s respectvely 400V and 500V. The degree of polluton must be specfed accordng to standard IEC Ths strongly nfluences the rated nsulaton voltage of a connector. Therefore, the rated nsulaton voltage of a connector should be reconsdered tme by tme for each degree of polluton.

24 enclosure versons and applcatons Changeover from Pg threads to M metrc threads After 31st December 1999, the German safety standard DIN VDE 0619 ( ) and the standards t refers to - DIN for dmensons wth metrc threads and DIN (T1-T4), DIN and DIN for dmensons wth Pg threads (Pg= Panzerrohr-Gewnde: lterally threads for armoured ppes ) - were wthdrawn and European standard EN Metrc cable grppers for electrcal nstallatons has been n force snce 1st January Ths standard defnes the new szes wth metrc threads for cable grppers accordng to EN and establshes the safety prescrptons. Conversely, t does not specfy the dmensons, such as the sze of the tghtenng wrench, the dagonal dmenson, or the dmensons of the tghtness seals, as was the case n the wthdrawn DIN for Pg cable grppers. The standard came defntvely nto force on 1st Aprl 2001, when the contrastng natonal standards were wthdrawn. It s vald n all member countres of CENELEC (European Electrcal Standardsaton Commttee) and ts publcaton has led to a broadenng of the supply of enclosures for mult-pole connectors for ndustral use, to nclude new enclosure versons wth cable entry sutable for metrc cable grppers. Cable grpper producers have ntroduced the new metrc seres to add to the Pg sze seres, to gradually replace the latter type. The transton perod ndcated n the new standard should have ended on 1st March 2001, after whch date the use of entry devces for Pg cables and, as a result, enclosures wth Pg thread, should have ended n new nstallatons. Nevertheless, both the cable entry devces and the relevant enclosures wth Pg thread, may contnue to be used as spare parts. For the CE markng of these tems, observance of the safety condtons specfed by the Low Voltage Drectve s suffcent. To dstngush hoods and surface-mountng housngs wth metrc entres from the relevant Pg versons (marked wth a C pre-code), the ILME metrc types are marked wth an M pre-code. The transposton table below ndcates the correspondence rule adopted n most cases by ILME for creatng the new metrc versons.

The standard s applcable to enclosures for electrc materals wth a rated power no greater than 72.5 kw. All the equpment must be nstalled accordng to the rule of art and must comply wth any manufacturer s assembly nstructons. When components of dfferent degrees of protecton are assembled, the resultng board or dstrbuton system wll assume the lowest degree of protecton of the mounted components. The range of ILME enclosures presented n ths catalogue offers the followng range of protecton: IP44: protecton aganst the penetraton of sold foregn objects wth a dameter equal to or greater than 1 mm and for protecton aganst the ntruson of dangerous parts wth an access calbre of Ø 1 mm (1 st dgt), and protected aganst the dangerous effects of water spray from all drectons (2 nd dgt). IP55: protecton aganst the penetraton of sold foregn objects wth a dameter equal to or greater than 1 mm and for protecton aganst the ntruson of dangerous parts wth an access calbre of Ø 1 mm (1 st dgt), and protected aganst the dangerous effects of water spray from all drectons (2 nd dgt). IP66: total protecton aganst dust and access to dangerous parts wth an accessblty calbre of Ø 1 mm (1 st dgt), and protected aganst powerful water jets such as sea waves (2 nd dgt). IP67: total protecton aganst dust, and from access to harmful parts wth accessblty of Ø 1mm (1 st dgt), and protecton aganst the effects of prolonged submerson (30 ) n water at the maxmum depth of 1 m (2 nd dgt) 1). IP69: total protecton aganst dust, and from access to harmful parts wth accessblty of Ø 1mm (1 st dgt), and protecton aganst water jets hgh pressure and hgh temperature (2 nd dgt). These enclosure have also successfully passed the tests requred for the IPX6 protecton ratng complant wth EN standard and for the IPX9K protecton ratng complant wth DIN standard. The followng table shows the dfferent levels of protecton requred by the IP standard. Frst Dgt Protecton of people aganst contact wth harmful parts IP Sold external Protecton objects none aganst sold objects wth Ø over 50 mm (e.g. contact wth hand) aganst sold objects wth Ø over 12 mm (e.g. contact wth fnger) aganst sold objects wth Ø over 2,5 mm (e.g. tools and wres) aganst sold objects wth Ø over 1 mm (e.g. fne tools and wres) aganst dust (no harmful depost) total aganst dust Second Dgt Protecton of materals aganst harmful penetraton of water IP Tests Protecton none aganst vertcal drops of water aganst drops of water wth an nclnaton of 15 from the vertcal aganst drops of water wth an nclnaton of 60 from the vertcal aganst splashng water from all drectons aganst water jets from all drectons aganst powerful water jets smlar to sea waves 1) The IP66/IP67 degree of protecton wll offcally be ntroduced n the next amendment 1 of the standards IEC EN and IEC EN (and of the relatng IEC standards). It s already accounted for n the IP degree of protecton standard EN as a versatle form of protecton, coverng the fact that the temporary mmerson resstance test (protecton IPX7) does not automatcally comply wth the two lower degrees of protecton IPX6 and IPX5, tested wth the respectve jet tests.
