적용 범위

This standard applies to polyvinyl chloride (PVC) artificial leather produced using coating, calendering, or lamination processes, whether foamed or unfoamed, with or without a substrate. It is primarily relevant for industries such as automotive interiors, building decoration, soft furniture, and apparel. It does not apply to non-PVC based synthetic leathers. Compliance is evaluated based on Type Test procedures.

기술 요구 사항

Chapter 3 of this standard outlines the mandatory limits for hazardous substances in PVC artificial leather. The standard specifically restricts the content of vinyl chloride monomer, soluble heavy metals (including lead and cadmium), and other volatile compounds. Manufacturers must ensure their products do not exceed these specified maximum concentration limits to be legally sold in the Chinese market. These requirements are designed to protect human health and improve living environments, particularly for products in close contact with daily life.

시험 방법

The standard specifies distinct testing methodologies for each restricted substance. Vinyl chloride monomer content is determined according to the method described in GB/T 4615-1984. Soluble heavy metals (lead and cadmium) are measured using an atomic absorption spectrophotometer with a flame atomization system, following an acid extraction process. Other volatile compounds are quantified by measuring mass loss after heating samples in an electric blast drying oven at specific temperatures, as referenced in GB/T 2918-1998.
