BS EN 479 is an international standard used for plastics that specifies the test methods and test procedures which helps in determining the heat reversion of poly(vinyl chloride) (PVC) based profiles.
BS EN 479 specifies a method for determining the heat reversion of unplasticized Poly(vinyl chloride) (PVC-U) profiles at 100 °C in air.
BS EN 479 is also applicable to PVC-based profiles at specified temperatures/other test conditions.
BS EN 479 on Determination of heat reversion of poly(vinyl chloride) (PVC) is useful for:
Polyvinyl chloride (PVC) is a synthetic resin made of polymerization of vinyl chloride. PVC is a commonly used polymer that helps in finding applications in a variety of products due to its excellent properties.
BS EN 479 helps in maintaining the test specimens in an oven at 100 °C for 1 h. This marked length of test specimens is useful in measuring these profiles before and after heating in the oven. BS EN 479 is useful in calculating the heat reversion by using the formula that is the percentage change of the final length relative to the initial length per pair of marks.
BS EN 479 specifies the test methods and test procedures for determining the heat reversion of Poly(vinyl chloride) (PVC) based profiles. This test method helps you ensure the sustainability of Poly(vinyl chloride) (PVC) based profiles that result in manufacturing good quality profiles.
