3、1. Scope*1.1 This specification covers chlorinated poly(vinyl chloride) (CPVC) pipe made in standard thermoplastic pipe dimensionratios and pressure rated for water (see Appendix). Included are criteria for classifying CPVC plastic pipe materials and CPVCplastic pipe, and requirements and test metho
4、ds for materials, workmanship, dimensions, sustained pressure, burst pressure,flattening, and extrusion quality. Methods of marking are also given.NOTE 1The CPVC pipe covered by this specification was covered previously in Specification D2241.NOTE 2The sustained and burst pressure test requirements
5、and the pressure ratings in the Appendix are calculated from stress values obtained fromtests made on pipe 2 in. (50 mm) and smaller. However, tests on larger pipe have shown these stress values to be valid.1.2 The products covered by this specification are intended for use with the distribution of
6、pressurized liquids only, which arechemically compatible with the piping materials. Due to inherent hazards associated with testing components and systems withcompressed air or other compressed gases some manufacturers do not allow pneumatic testing of their products. Consult withspecific product/co
7、mponent manufacturers for their specific testing procedures prior to pneumatic testing.NOTE 3Pressurized (compressed) air or other compressed gases contain large amounts of stored energy which present serious saftey hazards shoulda system fail for any reason.1.3 The text of this specification refere
8、nces notes, footnotes, and appendixes which provide explanatory material. These notesand footnotes (excluding those in tables and figures) shall not be considered as requirements of the specification.1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standa
9、rd. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.Within the text, the SI units are shown in brackets.1.5 The following safety hazards

This stress is c
21、ircumferential when internal hydrostatic waterpressure is applied.3.2.2 pressure rating (PR)the estimated maximum water pressure the pipe is capable of withstanding continuously with ahigh degree of certainty that failure of the pipe will not occur.3.2.3 relation between standard dimension ratio, hy
22、drostatic design stress, and pressure ratingthe following expression,commonly known as the ISO equation,5 is used in this specification to relate standard dimension ratio, hydrostatic design stress,and pressure rating:2 S/P 5 R 21or 2 S/P 5 D o /t! 21where:S = hydrostatic design stress, psi MPa,P =
23、pressure rating, psi kPa,D o = average outside diameter, in. mmt = minimum wall thickness, in. mm, andR = standard thermoplastic pipe dimension ratio (Do /t for CPVC pipe), also known as SDR.3.2.4 standard thermoplastic pipe dimension ratio (SDR)the standard thermoplastic pipe dimension ratio (SDR)
24、is the ratioof pipe diameter to wall thickness. For CPVC pipe it is calculated by dividing the average outside diameter of the pipe inmillimetres or in inches by the minimum wall thickness in millimetres or in inches. If the wall thickness calculated by this formulais less than 0.060 in. 1.52 mm, it
25、 shall be arbitrarily increased to 0.060 in. 1.52 mm. The SDR values shall be rounded to thenearest 0.5.3.2.5 standard thermoplastic pipe materials designation codethe pipe materials designation code shall consist of theabbreviation CPVC for the type of plastic, followed by the ASTM type and grade i
26、n Arabic numerals and the design stress in unitsof 100 psi 690 kPa with any decimal figures dropped. When the design stress code contains less than two figures, a cipher shallbe used before the number. Thus a complete material code shall consist of four letters and four figures for CPVC plastic pipe
