Abstract

This specification defines reclaimed 1,1,1-trichloroethane, also known commercially as methyl chloroform. The types are defined: Type I - high quality reclaimed 1,1,1-trichloroethane, approximating MIL Specification; Type II - good quality reclaimed solvent; and Type III - minimal acceptable reclaimed solvent. The solvent shall be subject to tests for amine acid acceptance or alkalinity, color and appearance, nonvolatile matter content, total acid acceptance, aluminum scratch, water-soluble halide ion content, acidity-alkalinity, and water content.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application.

1. Scope

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.
