For more iformatio o the ature ad extet of the revisio, see the revisio statemet o page 4. 2 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 3 for more iformatio o its calculatio. 3 For each elemet, the ucertaity listed is based o a statistical evaluatio of the cotributios of homogeeity ad the iterlaboratory testig program. See page 3 for more iformatio o its calculatio. 4 Values are give i weight percet. 5 Values i paretheses are ot certified ad are provided for iformatio oly. The requiremets of ISO Guides 30, 31, ad 35 were followed for the preparatio of this Certified Referece Material ad certificate of aalysis. Certificate Number REV101/ Page 1/5

3 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 times 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.

4 Aalysis: Chemical aalyses were made o samples take from bulk powder material. The origial participatig laboratories ormally followed the requiremets of ISO Guide The laboratories participatig i the stability testig followed the requiremets of ISO Stadard Methods of aalysis used were a those listed o page 2. Traceability: The followig Referece Materials were used to validate the aalytical data listed o pages 2-3 ECO Homogeeity: This Referece Material (RM) was tested for homogeeity usig ASTM Stadard Method E 826 ad foud acceptable. Validity statemet: ISO Guide 31 states that the certificatio should cotai a expiratio date for all materials where istability has bee demostrated or is cosidered possible, after which the certified value is o loger guarateed by the certifyig body. The certificatio of BS 101/5 is valid for 20 years from the date of this certificate. The certificatio is ullified if this RM is damaged, cotamiated, or otherwise modified. Storage: This RM will remai stable for twety years, provided that the bottle remais sealed ad is stored i a cool, dry atmosphere. Whe the bottle has bee opeed, the lid should be secured immediately after use. If the cotets should become discolored (eg. Oxidized) due to atmosphere cotamiatio, they should be discarded. Source: This material was produced by Joes & aughli Steel Plat; Aliquippa, PA. This material was made i a Basic Oxyge Furace.
