1.1 This test method covers the determination of several ac magnetic properties of either laminated ring or toroidal tape wound cores made from flat rolled product.
1.2 This test method covers test equipment and procedures for determination of specific core loss, specific exciting power, and peak permeability for power and audio frequencies (50 Hz to 20 000 Hz) under sinusoidal flux conditions.
1.3 This test method, because of the use of a feedback-controlled power amplifier, is well suited for determination of ac magnetic properties at magnetic flux densities above the knee of the magnetization curve and is particularly useful for testing of high-saturation iron-cobalt alloys (for example, alloys listed in Specification A801), although use of this test method is not restricted to a particular type of material.
1.4 This test method shall be used in conjunction with Practice A34/A34M and Terminology A340.
1.5 The values stated in either SI units or inch-pound units are to be regarded separately as standard. 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 non-conformance with the standard.
1.6 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.
1.7 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.

What People Are Saying

Thanks to the StandardsClub customer service team for helping me find the ASME BPVC-2023 SET I was looking for in a high-quality PDF version. Their assistance was excellent, and the document quality exceeded my expectations!

This standard document is very detailed, covering all relevant technical points, and provides comprehensive guidance for my project. The ANSI/NEMA Z535 SET was exactly what I needed, and I am very satisfied with the quality!

The purchasing process was straightforward, the price was very competitive, and the download was quick. The Tissue Engineering Standards Addressing Product Quality and Characterization Package was of excellent quality and provided all the information I needed. Definitely a great value for the price!
