ASTM D4457 Standard Test Method for the Determination of Dichloromethane and 1,1,1-Trichloroethane in Paints and Coatings by Direct Injection into a Gas Chromatograph

EUROLAB laboratory provides testing and compliance services within the scope of ASTM D4457 standard. This test method involves determining the amount of total dichloromethane or 1,1,1-trichloroethane or both in paints and coatings.

ASTM D4457 Standard Test Method for the Determination of Dichloromethane and 1,1,1-Trichloroethane in Paints and Coatings by Direct Injection into a Gas Chromatograph

Cellulose nitrate has been evaluated for alkyd, vinyl and styrene-butadiene systems. It has not yet been evaluated for other formulations, but is believed to be applicable.

The specified operating range for this test method is 1,1,1 to 31% for 65-trichloroethane and 32% to 78% for dichloromethane. There's no reason to believe it won't work outside of these ranges. The presence of 1-propanol in paints and coatings requires the use of a different internal standard.

Values ​​stated in inch-pound units should be considered standard. Values ​​in parentheses are mathematical conversions to non-standard SI units, provided for informational purposes only.

This standard does not purport to address all, if any, safety concerns associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory restrictions prior to use.
