Escopo e aplicabilidade

This standard applies to polyvinyl chloride (PVC) floor coverings, including foamed or non-foamed types, with or without substrates, produced via coating, calendering, or lamination processes. It also covers PVC composite kang mats and PVC vehicle flooring. It is crucial for manufacturers of indoor decorating materials to verify compliance with this regulation. The standard specifically targets the limitation of harmful substances in these products, referencing indoor decorating and refurbishing materials.

Requisitos técnicos

Chapter 3 of this standard contains mandatory clauses that specify strict limits on harmful substances in PVC floor coverings. Manufacturers must ensure their products meet these mandatory thresholds to access the Chinese market. The requirements cover the limitation of vinyl chloride monomer content within the PVC layer. Additionally, the standard prohibits the use of lead salt additives and sets maximum limits for soluble heavy metals, specifically soluble lead and soluble cadmium. Finally, it establishes distinct volatile substance limits categorized by product type, such as foamed versus non-foamed and glass fiber substrates versus other materials, evaluated according to GB/T 2918-1998.

Métodos de ensaio

The standard outlines specific testing procedures to verify compliance. Vinyl chloride monomer content is determined according to the methods specified in GB/T 4615-1984. For soluble heavy metals (lead and cadmium), the standard utilizes atomic absorption spectrometry (graphite furnace) to analyze sample extracts. Testing must be conducted after a 7-day aging period from the production date. The volatile substance content is measured by weighing samples before and after a 6-hour heating process in a blast drying oven, with results calculated per square meter.
