No other units of measurement are included in this standard. 1.4 This specification contains notes that are explanatory and are not part of the mandatory requirements of the specification. 1.5 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.
