About This Item
ASTM A698/A698M is the ASTM standard test method for evaluating magnetic shield efficiency in attenuating alternating magnetic fields. It provides a common technical basis for measuring how well a shielding material or assembly reduces alternating magnetic field strength, which is important when comparing products and verifying performance. By focusing on test method rather than product design, it supports consistent evaluation for engineering, procurement, and quality control decisions.
ASTM A698/A698M standard overview
The official title, Standard Test Method for Magnetic Shield Efficiency in Attenuating Alternating Magnetic Fields, indicates a measurement-focused standard intended to assess shielding performance under alternating magnetic field conditions. ASTM A698/A698M is used to help define how efficiency is determined so results can be compared more reliably across tests and products. This makes the standard useful when a consistent method is needed to document shielding capability, support compliance activities, or review product performance using an established ASTM test approach.
Where is ASTM A698/A698M used?
This standard is commonly used where magnetic shielding performance needs to be measured for materials, components, or assemblies exposed to alternating magnetic fields. It is relevant in testing and evaluation environments that work with shielding products, laboratory samples, or engineered enclosures designed to reduce magnetic interference. ASTM A698/A698M may also be used in supplier qualification and product verification workflows when buyers and manufacturers need a shared method for judging attenuation performance.
Practical importance of ASTM A698/A698M
ASTM A698/A698M matters because it helps create repeatable, comparable results for a specialized shielding property that can otherwise be difficult to assess consistently. Using a recognized ASTM test method supports better product evaluation, clearer procurement specifications, and more reliable quality control checks. It can also reduce uncertainty when validating shielding claims, since the same method can be applied across different test programs and technical reviews. That consistency is valuable for decision-making and risk reduction.
