Significance and Use
3.1 Poly(vinyl chloride) (PVC) is applied to coated fabrics as a dispersion of PVC particles in a liquid vehicle. During the processing of the fabric the PVC is fused or melted to produce a uniform film on the fabric. This test measures whether the PVC is converted, fused, or melted to produce a homogeneous film.
3.2 This conversion process is a melting of the crystallite structures in the polymer particles followed by solution of the molten polymer in the plasticizing vehicle. Fusion is important in the production of PVC-coated fabrics.
1.1 This test method describes a simple procedure to determine the completeness of fusion of poly(vinyl chloride) (PVC) dispersion coatings on fabric. This test applies primarily to coatings with a mechanical bond and does not include tie coating.
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.
