About This Item
ASTM A1013 defines a test method for measuring high-frequency core loss in soft magnetic core components at controlled temperatures using the voltmeter-ammeter-wattmeter method. It is a practical reference for evaluating how magnetic cores perform under conditions where frequency and temperature can affect losses. For engineers, buyers, and quality teams, ASTM A1013 helps create a consistent basis for comparing test results and supporting product selection, development, and compliance decisions.
What is ASTM A1013?
ASTM A1013 is a standardized test method focused on core loss measurement for soft magnetic core components over a high-frequency range of 10 kHz to 1 MHz. The method uses a voltmeter-ammeter-wattmeter approach and is intended for controlled-temperature testing, which helps improve repeatability and comparability. As an ASTM standard, it provides a defined technical framework for evaluating magnetic losses in components where performance can vary with operating conditions.
Where is ASTM A1013 used?
This standard is commonly used in laboratory testing, materials evaluation, and product development for soft magnetic core components. It is relevant anywhere high-frequency magnetic performance must be measured under controlled temperature conditions, such as in component qualification or comparative testing. ASTM A1013 is also useful in quality control workflows where consistent core-loss data is needed to assess material behavior and support engineering decisions before release or procurement.
Why is ASTM A1013 important?
ASTM A1013 matters because core-loss measurements can change significantly with frequency and temperature, making a consistent test method essential for reliable results. Using a recognized ASTM standard supports better comparison between suppliers, batches, and design options. It also helps reduce ambiguity in testing, strengthens quality control, and supports more confident product evaluation. For organizations that specify or purchase magnetic core components, ASTM A1013 can improve documentation and reduce technical risk.
