REQUIREMENTS 2.1 Composition, Appearance and Colour The labels shall comprise a curable coating on a pressure sensitive backing strip carried on a release carrier. The surface of the coating shall be smooth, free from coloured impurities and shall be white. The curable coating shall have no fractured edges. 2.2 Dimensions Height and width shall be in accordance with customer orders. The thickness shall be 0.15 ± 0.04mm exclusive of the release paper. 2.3 Test Requirements The test requirements shall be as specified in Table 1. 3. TEST METHODS 3.1 Preparation of Test Specimens 3.1.1 Printing 3.1.2 Curing The labels shall be printed using recommended printers and inks. Details of approved printers and inks are available from Tyco The labels shall be cured using the recommended cure methods, details of which are available from Tyco. 3.1.3 Adhesive Substrates Where specified for the test method cured labels 25mm wide x 175mm long shall be fixed to test plates of Aluminium. The Aluminium plates shall be degreased with Iso propyl alcohol and the labels applied as detailed in FINAT test method FTM1 using a standard 2Kg FINAT roller. (Note: This roller is specified in the FINAT Pressure Sensitive Laminates Suppliers and Users Technical Manual Section 2 (June 1980.)
RW 2518 Revision 1 Page 3 of 9 Date Printed 15-Apr-08 TEST METHODS (Cont d) 3.1.4 Conditioning Unless otherwise specified the labels fixed to the aluminium test plates shall be conditioned for 24 ± 2 hours at ambient temperature prior to testing to allow the pressure sensitive adhesive to develop optimum strength. 3.1.5 Number of Test Specimens Unless otherwise specified three specimens shall be used for each test. 3.2 Adherence of Cured Coating The test specimens shall be cured as specified in Clause 3.1.2 and then allowed to cool to ambient temperature. Each label shall be folded in half and creased with the coating uppermost. The coating shall be examined for evidence of cracking. 3.3 Adhesive Peel Strength Test specimens shall be prepared as specified in Clause 3.1. In addition to aluminium, test plates of the substrate materials listed in Table 1 shall be prepared as specified in Clause 3.1.3. The test method shall be as specified in. For tests at non-ambient conditions the test specimens shall be conditioned at the test temperature for a minimum of 20 minutes and a maximum of 60 minutes. 3.4 20 Minute Adhesion Test specimens shall be prepared as detailed in Clause 3.1 except that the conditioning period shall be 20 minutes ± 5 minutes prior to testing. 3.5 Print Legibility The test label shall be examined, using normal reading vision, and all patterns, colours and text shall remain unbroken and completely discernible. The labels shall also not show signs of any cracking, flaking, bubbling or lifting from the substrate. 3.6 Print Adherence The labels shall be tested as specified in SAE-AS-81531 paragraph 4.6.2.
RW 2518 Revision 1 Page 4 of 9 Date Printed 15-Apr-08 TEST METHODS (Cont d) 3.7 Dry Abrasion Resistance Test labels shall be prepared as specified in Clauses 3.1.1 and 3.1.2. The test method shall be as specified in BS 4781.A7 using a Taber Abrader. The wheel shall be a type CS10 with an applied loading, and number of cycles as specified in Table 1. 3.8 Wet Abrasion Resistance The test method shall be as specified in Clause 3.7 except that the abrading wheels shall be felt type CS5. The wheels shall be totally immersed in the test fluid for 1h ± 10 minutes, removed and blotted dry with absorbent paper towelling and then allowed to dry for 1h ± 10 minutes before the test. The applied load and number of cycles shall be specified in Table 1. 3.9 Print Permanence The specimens shall be prepared as specified in Clause 3.1 excluding the conditioning period. The test method shall be as specified for resistance to solvents in MIL-STD-202F, method 215. 3.10 Light Fastness (Xenon Arc) The test specimens shall be prepared as specified in Clause 3.1 excluding the conditioning period. The test method shall be as specified in ASTM G26 Method D. Test for the time specified in Table 1. 3.11 Humidity Steady State The test specimens shall be prepared as specified in Clause 3.1 and then subjected to the time, temperature and humidity specified in Table 1. 3.12 Thermal Cycling The test specimens shall be prepared as specified in Clause 3.1 and then subjected to 10 cycles as specified in Table 1: The change over time between each temperature shall not exceed 5 minutes. Note : Samples may experience a colour shade change. 3.13 Thermal Ageing The test specimens shall be prepared as specified in Clause 3.1 and then subjected to the time and temperature specified in Table 1. Note : Samples may experience a colour shade change.
RW 2518 Revision 1 Page 5 of 9 Date Printed 15-Apr-08 TEST METHODS (Cont d) 3.14 Low Temperature Flexibility The test label with dimensions of 25mm x 38.5mm shall be applied to a 6mm diameter cable and conditioned as stated in Table 1. After conditioning the cable shall be wrapped round a preconditioned mandrel of 60mm diameter in a close helix. 3.15 Fungus Resistance The test specimens shall be prepared as specified in Clause 3.1. The test method shall be as specified in BS 2011 Part 2.1 J Variant 1. 3.16 Low Fire Hazard Characteristics In accordance with BR1326(A) Class 5 for use in submarine atmospheres. External Approval by UK Navy. 3.17 Chemical Resistance The test specimens shall be prepared as specified in Clause 3.1 and immersed for the time and temperature in one of the chemicals listed in Table 1 The specimens shall be removed from the chemical, lightly wiped and air dried for 2 hours ± 15 minutes. The test shall be repeated on the remaining specified fluids using fresh samples. Note: In the case of Skydrol the sample shall be lightly wiped not more than two times before drying. To meet the Skydrol immersion requirement the sample must be oven cured for 5 minutes at a temperature of 150 c
