1. Scope

control.
1.2 The following precautionary caveat pertains only to the test method portion, Section 9, of this standard: This standard does not purport to address the safety problems 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.
