This Malaysian Standard covers chlorinated poly(vinyl chloride) (PVC-C) pipe made in Schedules 40 and 80 sizes and pressure-rated for water. Included are criteria for classifying PVC-C plastic pipe materials and PVC-C plastic pipe, a system of nomenclature for PVC-C plastic pipe and requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening and extrusion quality. Methods of marking are also given.
NOTE. The sustained and burst pressure test requirements, and the pressure ratings in Annex A, are calculated from stress values obtained from tests made on pipe 50 mm (2 inch) and smaller. However, tests on larger pipe have shown these stress values to be valid.
The products covered by this standard are intended for use with the distribution of pressurised liquids only, which are chemically compatible with the piping materials.
NOTES:
1. Due to inherent hazards associated with testing components and systems with compressed air
