These test methods for the chemical analysis of zinc metals and alloys are primarily intended as referee methods to test such materials for compliance with compositional specifications. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.

1.1 These test methods cover the chemical analysis of zinc and zinc alloys having chemical compositions within the following limits:

1.2 These test methods appear as follows:

1.3 This standard does not purport to address all of the safety concerns if any associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 6.

1.1 This specification covers zinc and zinc alloy wire used to deposit zinc coatings by thermal spraying (metallizing) for the corrosion protection of steel and iron. Zinc and zinc alloy wire provided under this specification is intended for use in oxy-fuel and electric arc thermal spraying equipment. Additional zinc alloy compositions used in thermal spraying primarily for electronic applications are found in Specification B943.

1.2 Zinc alloy wire compositions used in thermal spraying primarily for electronic applications are found in Specification B943.

1.3 Zinc alloy wire compositions used as solders are found in Specification B907.

1.4 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.

1.5 This standard does not purport to address all of the safety concerns if any associated with its use. It is the responsibility of the user of this standard to become familiar with all hazards including those identified in the appropriate Material Safety Data Sheet (MSDS) for this product/material as provided by the manufacturer to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This practice used in conjunction with an appropriate quantitative optical emission spectrochemical method is suitable for use in manufacturing control material or product acceptance and development and research.

1.1 This practice covers the sampling of zinc and zinc alloys to obtain a sample suitable for quantitative optical emission spectrochemical analysis. Included are procedures for obtaining representative samples from molten metal from fabricated or cast products that can be melted and from other forms that cannot be melted.

1.2 This standard does not purport to address all of the safety concerns if any associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
