The values given in parentheses are for information only.<\/p>\n<p>1.3 This standard does not purport to address all of the safety problems, 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. For specific hazard statements see Notes 2 through 5.<\/p>\n<p>Note 1-A qualitative determination of glycol-base antifreeze is provided in Test Method D2982.
