Certificate of Aalysis BS 718D Certified Referece Material for 718 Nickel Alloy - UNS Number N07718 Certified Estimate of Certified Values 3 Certified Estimate of Value 1 Ucertaity 2 Value 1 Ucertaity 2 Al P As S B Si C S Co Ti Cr V Cu W Fe Mg M Mo N Nb Ni O Iformatioal Values 3,4 Ca (0.0006) Pb ( ) Sb (0.0002) Ta (0.0022) Zr (0.002) 1 For each elemet, the certified value listed is the preset best estimate of the true value based o the mea of the weighted results of a iterlaboratory testig program. See page 4 for more iformatio o its calculatio. 2 For each elemet, the ucertaity listed is based o a statistical evaluatio of the cotributios of homogeeity ad the iterlaboratory testig program. See page 4 for more iformatio o its calculatio. 3 Values are give i weight percet. Values i brackets are reported by differece. 4 Values i paretheses are ot certified ad are provided for iformatio oly. Trace elemet iformatio values for Bi, Cl, Ga, Ge, K, Na, Re, Se, Te, ad Z are show o page 4. The requiremets of ISO Guides 31, 34, ad 35 were followed for the preparatio of this Certified Referece Material ad certificate of aalysis. This is a Certified Referece Material as defied by ISO Guide 30. Certificate Number 718D Page 1/7

4 For each elemet, i accordace with the requiremets of ISO Guides 34 ad 35, a effort must be made to accout for the effects o the certified value of the ucertaity estimate from homogeeity testig (H) ad the ucertaities of the cotributig laboratories. The average (A) is calculated usig a weighted mea where the reciprocal of the square of each laboratory s combied ucertaity (C ), calculated from its stadard deviatio (S ) ad its ucertaity estimate (U ), is used as the weight (W ) for it s mea (M ). The stadard deviatio (S) is calculated as the square root of the reciprocal of the sum of the weights. U 1 is the combied ucertaity from homogeeity ad labs. U 2 is U 1 multiplied by the coverage factor (95 % t-statistic). U 3 is U 2 divided by the square root of the umber of determiatios (). Thus: C S U 2 2 W 1 C 2 A i 1 W M i1 W S 1 W i1 2 2 U H S U t U U U 2 All but the fial reported values are take to two sigificat figures as determied by each quatity s ucertaity estimate. The fial reported Ucertaity is U 3 rouded to oe sigificat figure ad represets the half width of the 95 % cofidece iterval for the Certified value. The fial reported Certified value is A rouded to the same decimal place as the Ucertaity. The Ucertaity is a measure of the quality of the Certified value. The Tolerace is a measure of the expected performace of a aalysis. This ivolves further expadig the sample ucertaity to iclude istrumet ad operator ucertaity, for those without access to such calculatios. For further iformatio regardig the cofidece iterval for the certified value see ISO Guide 35:2006 sectio 6.
