Terminology3.
24、1 Definitions:3.1.1 GeneralDefinitions used in this specification are inaccordance with Terminology F412, unless otherwise speci-fied. The abbreviation for chlorinated poly(vinyl chlo-ride) isCPVC. Plastic tubing denotes a particular diameter schedule ofplastic pipe in which the outside diameter of
25、the tubing is equalto the nominal size plus18 in. (3.18 mm).3.1.2 relation between standard dimension ratio, stress, andinternal pressurethe following expression is used to relatestandard dimension ratio, stress, and internal pressure for pipeand tubing:2S/P 5 R 2 1 (1)or2 S/P 5D0/t !21 (2)where:S =
26、 stress in circumferential or hoop direction, psi(MPa),P = internal pressure, psi (MPa),D0= average outside diameter, in. (mm),t = minimum wall thickness, in. (mm), andR = standard dimension ratio, SDR3.1.3 standard dimension ratio (SDR)a selected series ofnumbers in which the average outside diamet
27、er to minimumwall thickness dimension ratios are constant for all sizes ofpipe and tubing in each standard dimension ratio, and whichare the ANSI Z17.1 Preferred Number Series 10 modified by+1. SDR fittings shall by definition be equivalent in minimumsocket wall thickness to the minimum wall thickne
28、ss of thecorresponding SDR and size of pipe or tubing, and theminimum body wall thickness shall be 125 % of that value.3.1.4 standard material designation codethe chlorinatedpoly(vinyl chloride) material designation code shall consist ofthe abbreviation CPVC followed by two digits indicating theASTM
29、 type and grade in Arabic numerals. Where necessary, athird and fourth digit shall be added to indicate the hydrostaticdesign stress for water at 73F 23C in units of 100 psi 0.69MPa.4.

34、6M 09b12meeting the requirements of this specification are categorizedby two criteria; namely, basic short-term properties, andlong-term hydrostatic strength. Sections 5.1.1 and 5.1.2 respec-tively define these categories.5.1.1 Basic Short-Term PropertiesThis specification cov-ers CPVC 41 pipe, tubi
35、ng, and fittings made from plasticmaterials meeting the mechanical strength, heat resistance,flammability, and chemical resistance requirements for CPVC23447 in Specification D1784.NOTE 4CPVC 23447 was formerly designated as CPVC Type IVGrade 1, and is herein designated as CPVC 41. This is also used
36、 inmarking pipe, tubing, or fittings.5.1.2 Long-Term Hydrostatic Strength This specificationcovers CPVC 41 pipe, tubing, and fittings which are furtherdefined by hydrostatic design stress as CPVC 4120. Pipe andtubing are so defined on the basis of long-term hydrostaticstrength tests and are made fro
37、m compounds having anestablished 180F 82C hydrostatic design stress of 500 psi3.45 MPa or greater in accordance with Test Method D2837.Fittings are so defined by hydrostatic sustained pressure testson fitting assemblies, required by this specification (see 6.2),based on the hydrostatic strength of t
38、he corresponding pipe ortubing.NOTE 5No hydrostatic design stress, as such, exists for fittings untilsuch time as long-term hydrostatic strength test methods for fittings aredeveloped.5.2 The PEX fitting ends of CPVC to PEX transition fittingsshall meet the material and dimensional requirements of t
39、hecorresponding PEX fitting standard.5.3 The PERT fitting ends of CPVC to PERT transitionfittings shall meet the material and dimensional requirementsof the corresponding PERT fitting standard.5.4 Rework MaterialClean rework plastic material gener-ated from the manufacturers own plastic tube or fitt
