Active Standard ASTM A1073 / A1073M | Developed by Subcommittee: A05.07
Book of Standards Volume: 01.06
Historical (view previous versions of standard)
1.1 This practice defines procedures for measuring the thickness of nonmetallic and metallic-coated steel sheet. Thickness is a significant quality characteristic of steel sheet products. The ability to accurately measure thickness using hand micrometers is critical in determining product conformance to specifications. The methods described are designed and intended for use in both laboratory and plant situations and their environments.
1.2 The flat steel product shall conform to all the requirements of the appropriate specifications as follows: Specifications A924/A924M and A917.
1.3 Quantitative limits are not addressed and are established in the general requirements, or individual product specifications, or both; or when applicable, as agreed to between supplier and user.
1.4 This specification is applicable to orders in either inch-pound units or SI units. Values in inch-pound and SI units are not necessarily equivalent. Within the text, SI units are shown in brackets. Each system shall be used independently of the other.
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 establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
