EUROLAB laboratory provides testing and compliance services within the scope of ASTM A664 standard. The ASTM A664 standard covers the procedure for determining standard grades (within ASTM specifications) of flat rolled electrical steels made to specified maximum values of specific core loss.
This application applies to magnetically soft irons and steels (low carbon steels and ferrous alloys containing silicon, aluminum and other alloying elements), a core loss measurement (1,5 kG) of alternating induction at a specified peak value and a specified frequency such as 15 T. ) and 60 Hz are normally used to grade the material.
This practice also applies when another property is specified as the limiting characteristic (or a different induction or frequency, or both), provided the material meets all the requirements of the ASTM specification.
This application covers the determination procedure for standard quality flat rolled electrical steels made according to the specified maximum core loss values. This application is applied to low carbon steels and iron, silicon, aluminum etc. where a core loss measurement is made at a specified peak value and a specified frequency of alternating induction. Applies to magnetically soft irons and steels such as alloys with This practice also applies when there is another property.
The individual specifications suitable for this application are Specifications A677 , A683 , A726 , A876 and A1086 .
Values stated in SI units should be accepted as standard. The values in parentheses are mathematical conversions to conventional (cgs-emu and inch-pound) units that are provided for informational purposes only and are not considered standard.
This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
