1、Designation: D5394 02 (Reapproved 2012)Standard Specification forReclaimed 1,1,1-Trichloroethane1This standard is issued under the fixed designation D5394; 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 () 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 qualit
3、y 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 th
4、e 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.

9、richloroethane, Type III, shall con-form to the requirements of Table 3. See STP-403A.3.4 This specification does not address the possibility ofproduct flash points due to the presence of flammable constitu-ents. However, flash point must be determined for properlabeling and shipment. The Tag closed
10、-cup procedure isrecommended.3.5 Specific gravity for these grades typically will bebetween 1.25 and 1.37.4. Hazards4.1 Due to the possible presence of low level foreigncontaminants in reclaimed 1,1,1-trichloroethane, the user iscautioned to use due care in determining the effects of thesecontaminan
