Description

This standard specifies chlorinated poly (vinyl chloride) (CPVC) pipes made in Schedule 40 and Schedule 80 sizes and pressure-rated for water (see Annex).This standard includes criteria for classifying CPVC plastic pipe materials and CPVC plastic pipes, a system of nomenclature for CPVC plastic pipes, requirements and test methods for materials, workmanship, dimensions, sustained pressure, burst pressure, flattening and extrusion quality. Methods of marking are also given. NOTE 1 The sustained and burst pressure test requirements and the pressure ratings in the Annex are calculated from stress values obtained from tests made on pipe 50 mm (2 inch) and smaller sizes. However, tests on larger pipes have shown these stress values to be valid.The products covered by this standard are intended for use with the distribution of pressurized liquids only, which are chemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases, some manufacturers do not allow pneumatic testing of their products. Consultation should therefore be made with specific product/component manufacturers for their specific testing procedures prior to pneumatic testing. NOTE 2 Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious safety hazards should a system fail for any reason. This standard references notes and Annex which provide explanatory information. The notes (excluding those in tables and figures) shall not be considered as requirements of the standard.The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independent of the other. Combining values from the two systems may result in non-conformance with the standard. The following safety hazards warning pertains only to the test methods (Clause 9) of this standard: Retrieving data. Wait a few seconds and try to cut or copy again.

Demand Quality

When things don't work as they should, it often means that standards are absent.
