1.1 This specification defines Type I (high quality reclaimed 1,1,1-trichloroethane, approximating MIL Specification), Type II (good quality reclaimed solvent), Type III (minimal acceptable reclaimed solvent).
1.2 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. For a specific hazards statement see Section 4.
1.3 1,1,1-trichloroethane also is known commercially as methyl chloroform.
