Historical Standard: ASTM D3749-95(2002) Standard Test Method for Residual Vinyl Chloride Monomer in Poly(Vinyl Chloride) Resins by Gas Chromatographic Headspace Technique
SUPERSEDED (see Active link, below)
ASTM D3749
1. Scope
1.1 This test method is suitable for determining the residual vinyl chloride monomer (RVCM) content of poly(vinyl chloride) (PVC) homopolymer and copolymer resins for uses other than food contact. The range for this test, based on interlaboratory evaluation, is from 0.1 to 400 ppm RVCM.
1.2 This test method can be adapted to determinations of RVCM in a PVC copolymer resin if the Henry's Law constant at 90C for that copolymer is known.
1.3 This test method cannot be used for polymer in fused forms, such as cubes or sheets. Refer to Test Method D 4443 or Test Method D 3680 for these materials.
1.4 This test method is proposed as an alternative to EPA Method 107 for determination of vinyl chloride monomers in dry-resin samples.
1.5 The values stated SI units are to be regarded as the standard.
1.6 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.
Note 1This test method is similar to ISO 6401-1985 in title only. The technical content is significantly different.
