Standard Specification for Vapor-Degreasing Grade and General Solvent Grade 1,1,1-Trichloroethane
Use of 1,1,1-trichloroethane and dichloromethane, which do not measurably contribute to the atmospheric oxidant level, is a way for industry to meet government or other regulations on volatile organic compounds. This test method is designed to determine the content of these halohydrocarbon solvents in paints and coatings. That content can subsequently be used in calculating the volatile organic compound content of a coating. 1.1 This test method covers the determination of total amount of dichloromethane or 1,1,1-trichloroethane, or both, in paints and coatings. It has been evaluated for cellulose nitrate, alkyd, vinyl, and styrene-butadiene systems. It has not yet been evaluated for other formulations, but is believed to be applicable. The established working range of this test method is from 31 to 65 % for 1,1,1-trichloroethane and 32 to 78 % for dichloromethane. There is no reason to believe it will not work outside of these ranges. The presence of 1-propanol in paints and coatings requires the use of a different internal standard. (See also Practice E 260.) 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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. Specific hazard statements are given in Section 7.

Standard Test Method for Determination of Dichloromethane and 1,1,1-Trichloroethane in Paints and Coatings by Direct Injection into a Gas Chromatograph
The degradation of insufficiently stabilized 1,1,1-trichloroethane, in the presence of aluminum, results in the formation of hydrochloric acid and polymeric residue. Thus, if such degradation is allowed to continue, the aluminum will be corroded and the 1,1,1-trichloroethane rendered unusable. The presence of free water invalidates this test method. This test method can be used to determine if 1,1,1-trichloroethane is sufficiently stabilized to inhibit reaction with aluminum or aluminum alloys. Solvent passing this test method still may not be stable for all applications. Consult a producer for use applications. Aluminum should not be used as a material of construction for pumps, tanks, pipelines, valves, spray equipment, or other handling equipment used for chlorinated solvents. Properly stabilized halogenated solvents are, however, commonly used in cleaning aluminum and other sensitive metals.1.1 This is a screening test method to determine if sufficient inhibitors are present in 1,1,1-trichloroethane to provide at least minimal stability in the presence of aluminum.1.2 Solvent passing this test method may not be stable for all applications.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.
