【国外标准】 Standard Test Methods for Glycerol, Ethylene Glycol, and Pentaerythritol in Alkyd Resins (Withdrawn 2004)

1.1 These test methods cover the determination of glycerol, ethylene glycol, and pentaerythritol in alkyd resins and resin solutions. Other polyhydric alcohols that can be oxidized by periodic acid to formaldehyde or formic acid, or both, will interfere with the determination of glycerol and ethylene glycol (see Test Methods D2456 or D2998). Urea, melamine, or phenolic resins interfere and render this procedure inapplicable. 1.2 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.
