Standard Practice for Using Hand Micrometers to Measure the Thickness of Uncoated Steel Sheet and Nonmetallic and Metallic-Coated Steel Sheet

Importancia y uso:

4.1 This practice provides procedures commonly used for measuring the thickness of steel sheet products under the jurisdiction of ASTM Committees A01 and A05 and their subcommittees as designated by a purchaser in a purchase order or contract.

4.2 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 procedures for measuring thickness characteristics of steel sheet products are provided so that purchasers and suppliers have common measuring procedures for thickness measurements. The intention of these measuring methods is not to provide dimensional specifications for thickness characteristics, but rather common procedures for quantifying thickness values. For determining compliance with thickness specifications, references are provided to appropriate ASTM standards.

4.3 This practice may be used by other ASTM Committees and other standards writing bodies for the purpose of measuring thickness of metal sheet products.
