1、Designation: D 5394 02 (Reapproved 2007)Standard Specification forReclaimed 1,1,1-Trichloroethane1This standard is issued under the fixed designation D 5394; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revision

2、. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification defines Type I (high quality reclaimed1,1,1-trichloroethane, approximating MIL Specification), TypeII (good qua

3、lity reclaimed solvent), Type III (minimal accept-able reclaimed solvent).1.2 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine

4、 the applica-bility of regulatory limitations prior to use. For a specifichazards statement see Section 4.1.3 1,1,1-trichloroethane also is known commercially asmethyl chloroform.2.
