Description

ASTM A754/A754M-21

Redline Standard: Standard Test Method for Coating Weight [Mass] of Metallic Coatings on Steel by X-Ray Fluorescence

ASTM A754/A754M

Scope

1.1 This test method covers the use of X-ray fluorescence (XRF) for determining the coating weight [mass] of metallic coatings on steel sheet. The test method is intended to be used for “on-line” measurements of coating on continuous production lines and includes procedures for both X-ray tube and isotope coating weight [mass] equipment. In the body of this test method, reference to zinc coating shall be interpreted to also include zinc alloy coating except where specifically stated otherwise.

1.2 This test method is applicable to the coatings covered by the following ASTM Specifications: A463/A463M, A599/A599M, A623, A623M, A653/A653M, A792/A792M, A875/A875M, A879/A879M, A918, A924/A924M, A1046/A1046M, A1063/A1063M, and A1079.

1.3 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.

1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
