【国外标准】 Standard Specification for Reclaimed Trichloroethylene

This specification covers the grades of trichloroethylene typically needed in various industries for noncritical applications such as in metal cleaning formulations. It may also be used as a reference document by purchasers or persons establishing in-house trichloroethylene recovery programs. The specimens are classified into three types: Type I – generally recognized for use in precision applications; Type II – for use in less-demanding precision applications; and Type III – may not be suitable for all applications. The three types of reclaimed trichloroethylene shall meet the specific gravity, nonvolatile residue, water content, assay percentage, 1,1,1 trichloroethane content, color in platinum-cobalt scale, appearance, acid acceptance, and acidity requirements.1.1 This specification covers the grades of trichloroethylene2 typically needed in various industries for noncritical applications such as in metal cleaning formulations. It may be used as a reference document by purchasers or persons establishing in-house trichloroethylene recovery programs.1.2 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
