What is BS EN 478 - Determination of appearance of Poly (vinyl chloride) (PVC) based profiles about?
BS EN 478 is an international standard used for plastics that specifies the test method and test procedures which helps in determining the appearance of Poly (vinyl chloride) (PVC) based profiles after heated at 150 °C.
BS EN 478 specifies a method for determining the effect of heat on unplasticized poly (vinyl chloride) (PVC-U) profiles, to be carried out in air at 150 °C.
BS EN 478 is also applicable to PVC-based profiles at specified temperatures/test conditions.
Who is BS EN 478 - Determination of appearance of Poly (vinyl chloride) (PVC) based profiles for?
BS EN 478 on Determination of appearance of Poly (vinyl chloride) (PVC) based profiles is useful for:
- Manufacturers of automobile
- Manufacturers of electronic devices
- Construction of the building
- Manufacturers of pipes and tubes
- Health care centres
Why should you use BS EN 478 - Determination of appearance of Poly (vinyl chloride) (PVC) based profiles?
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 and low cost.
BS EN 478 helps in maintaining the length of profiles in the oven at 150 °C for 30 min. This helps in sustaining the poly (vinyl chloride) (PVC) based profiles at different temperatures. With the help of visual inspection on the inside, outside and the cross-section of the wall, you can identify the defects which can appear after the heating process.
BS EN 478 specifies the test methods and test procedures for determining the appearance of poly (vinyl chloride) (PVC) based profiles when exposed at 150 °C. This test method is useful in manufacturing good quality profiles.
