Certificate of Aalysis BS XCCS-1 Certified Referece Material for Carbo Steel Certified Estimate of Certified Values 3 Certified Estimate of Value 1 Ucertaity 2 Value 1 Ucertaity 2 Al S As Ti C V Ca Zr Co Cr Cu Fe M Mo N Ni P S Si Iformatioal Values 3,4 B (0.0004) Mg (0.0003) Nb (0.001) Pb (0.0006) Sb (0.0005) W (0.003) 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 O 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 XCCS Page 1/7

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 Tolerace is the half width of the 95 % cofidece iterval for measuremets 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. For further iformatio regardig the cofidece iterval for the certified value see ISO Guide 35:2006 sectio 6.
