Abstract

This specification concerns general procedures for specifying requirements of flat-rolled electrical steels for magnetic applications. This specification is to be used when the material in question is not covered by an ASTM material specification. The specification does not contain requirements but instead lists physical properties, ordering information and other attributes that should be considered when purchasing the material. All ASTM electrical steel specifications are in conformity to this specification.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.

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 , and A876 .

Note 1For 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 following safety hazards caveat pertains only to the test methods portion, Section 13, of this specification. 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.
