Doplňujúce informácie
| Significance and Use | ||||
|
5.1 Vinyl chloride-containing polymers are widely used to package a variety of materials, including foods. 5.2 Vinyl chloride monomer has been shown to be a human carcinogen. Threshold toxicity value has not been established. 5.3 Plastic manufacturers, food packagers, government agencies, etc. have a need to know the residual vinyl chloride monomer content of vinyl chloride-containing polymers. |
||||
| 1. Scope | ||||
|
1.1 This test method is suitable for determining the residual vinyl chloride monomer (RVM) content of homopolymer and copolymers of vinyl chloride down to a level of ∼5 ppb. 1.2 This test method is applicable to any polymer form, such as resin, compound, film, bottle wall, etc. that can be dissolved in a suitable solvent. |
