ASTM A971/A971M-17-Reapproved2022

Active Standard: Standard Test Method for Measuring Edge Taper and Crown of Flat-Rolled Electrical Steel Coils

ASTM A971/A971M

Scope

1.1 This test method provides a procedure for measuring edge taper and crown of flat-rolled electrical steel coils as produced at the steel mill.

1.2 The values and equations stated in customary (cgs-emu and inch-pound) units or SI units are to be regarded separately as standard. Within this standard, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with this standard.

1.3 The following material specifications include requirements for edge taper or crown: A677, A683, A726, A876, and A1086. Specification A840 also includes requirements for edge taper or crown, but it has been withdrawn and reference to it is included for historical purposes.

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.
