Sampling for Determination of Chemical Composition7.1 Sampling procedures shall be in accordance with appro-priate provisions of Specification B949, Section 6.8. Methods of Chemical Analysis8.1 The determination of chemical composition shall be

16、made in accordance 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, ISO3815-2 or b

17、y a method agreed upon by both parties, shall be thebasis 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 experi
