1 Scope

This standard specifies the materials for water-based impact-modified polyvinyl chloride (PVC-M) pipe and fittings, product classification, requirements, test methods, Inspection rules, signs, packaging, transportation, storage.

This standard applies to polyvinyl chloride resin as the main raw material, through the physical modification of the extrusion molding of the pipe and injection molding pipe.

The pipe and fittings specified in this standard are applicable to the delivery of domestic drinking water and general-purpose water under pressure and the water temperature does not exceed 45 °C.
