The values ineach s
5、ystem are not exact equivalents, therefore, each system isto be used independently of the other, without combiningvalues in any way.1.4 The following precautionary statement pertains to thetest method portion, Section 14 of this specification: Thisstandard does not purport to address all of the safe
6、ty concerns,if any, associated with its use.
