ASTM WK92176
Revision of A932/A932M-01(2019) Standard Test Method for Alternating-Current Magnetic Properties of Amorphous Materials at Power Frequencies Using Wattmeter-Ammeter-Voltmeter Method with Sheet Specimens
Rationale
Form Factor Equation referenced in Sections 7.4, 7.9.1, and twice in 9.7 is incorrect. It is a factor, so it should be a constant, but the image of Pi>sqrt2/4 is an equation, which means nothing. The ">" should be a multiplication symbol, making the factor Pi*sqrt2/4, which is a constant of approximately 1.1107.
