As a widely used plastic material, polyvinyl chloride (PVC) plays an important role in many fields. Understanding its implementation standards is of great significance to related industries.
From an international perspective, ISO has formulated standards such as ISO 1167 series on test methods for PVC pipes and fittings. ASTM has also issued relevant standards such as D1784 for testing methods for physical properties of PVC pipes. ANSI/NSF in the United States has formulated standards such as 61 to ensure drinking water safety for PVC pipes and fittings, and UL has test standards such as UL 94 flame retardant properties for PVC wires and cables.
In Europe, CEN's EN 1451 series involves PVC-U pipes and fittings requirements, and BSI's BS 4637 specifies PVC window frame performance requirements. At the same time, the EU's RoHS directive restricts the use of certain hazardous substances in electrical and electronic equipment, and PVC film as part of electronic equipment must comply; REACH regulations require chemical registration, etc., and the production and use of PVC film must also comply.
In China, national standards such as GB/T 5761-2006 stipulate PVC resin test methods, GB/T 5836.1-2018 has requirements for PVC hoses, and JG/T 305-2011 stipulates PVC-U building drainage pipe requirements. In the chemical industry, HG/T 2877-2011 stipulates the production, inspection and packaging requirements of polyvinyl chloride calendered films. In addition, specific application areas have different requirements, such as PVC films in the construction field must comply with the combustion performance classification standards, and the medical field must comply with biocompatibility and safety standards.
In short, PVC implementation standards cover many aspects and are an important basis for product quality and market access. Foreign trade companies need to pay attention to ensuring product compliance.
