1.1 This specification covers the performance requirements of CPVC pipe, fittings and solvent cements used in chemical waste drainage systems.

1.2 A system is made up of pipe, fittings and solvent cement that meet the requirements of this standard.

Note 1: Consult the manufacturer’s chemical resistance recommendations for chemical waste drainage applications prior to use.

1.3 The text of this specification references notes, footnotes and appendices that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.

1.4 The pressure tests described in this standard are laboratory hydrostatic tests that are intended to verify joint/system integrity. They are not intended for use as field tests of installed systems.

1.5 Due to inherent hazards associated with testing components and systems with compressed air or other compressed gases, no such testing shall be done unless the component manufacturer gives approval in writing.

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.

1.6 Mechanical joints used for joining pipe and fittings of different materials are provided for in this specification. They include common flanges, couplings, and unions.

1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Note 3: This specification specifies dimensional, performance, and test requirements for fluid handling applications but does not address venting of combustion gases.

1.9 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
