Methods of Chemical Analysis8.1 The determination of chemical composition shall bemade in acc
16、ordance with Specification B949, Section 5.2.2.8.2 The determination of chemical composition shall bemade in accordance with suitable chemical Test Methods E536,ISO 3815-1, ISO 3815-2 or other methods. In case of dispute,the results secured by Test Methods E536, ISO 3815-1,ISO 3815-2 or by a method
17、agreed upon by both parties, shallbe the basis of acceptance.NOTE 1Test Methods E536 is not directly applicable to ACuZinc5.ISO 3815-1 and ISO 3815-2 are generic methods applied to zinc and zincalloys. Each of the methods may be modified and formatted for the alloyto be assayed. An experienced chemi
18、st, using suitable and/or traceablestandards along with valid quality assurance techniques, will be able toperform and validate the methods and demonstrate acceptable precisionand accuracy.8.3 For purposes of determining compliance with specifiedcomposition limits as given in Table 1, an observed or
19、calculated value shall be rounded to the nearest unit in the lastright-hand place of figures shown in Table 1, in accordancewith the rounding method of Practice E29.9.
