1.1 This specification covers technically important, commercially available, magnetically hard sintered ceramic ferrite permanent magnets.

1.2 Ceramic ferrite magnets have residual magnetic induction Br from 2000 G (0.2 T) up to about 5000 G (0.5 T) and intrinsic coercive field strength Hci (HcJ) from 2000 Oe (160 kA/m) up to about 5000 Oe (400 kA/m). Their specific magnetic hysteresis behavior (demagnetization curve) can be characterized using Test Method A 977/A 977M.

1.3 The values stated in customary (cgs-emu and inch-pound) units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units which are provided for information only and are not considered standard.

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 and health practices and determine the applicability of regulatory limitations prior to use.
