ASTM A345-19 - 1.4.2019
 
1. Scope

1.1 This specification covers general procedures for specifying requirements in the procurement and delivery of flat-rolled electrical steels for magnetic applications. When an applicable individual specification does not exist, this specification enables the user to order a suitable material to be supplied under controlled conditions with respect to magnetic quality, sampling, testing, packaging, and so forth, by specifying certain requirements on the purchase order and citing this specification.

1.2 Individual ASTM electrical steel specifications that are in conformity with this specification are Specifications A677, A683, A726, A840, A876, and A1086.

Note 1: For more information on other standards associated with this specification, refer to the following: Test Methods A341/A341M, A343/A343M, A348/A348M, A596/A596M, A712, A717/A717M, A719/A719M, A720/A720M, A721/A721M, A773/A773M, A804/A804M, A889/A889M, A937/A937M, A971/A971M, and Practice A664.

1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to customary (cgs-emu and inch-pound) units which are provided for information only and are not considered standard.

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.
