2、 case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S. Department of Defense.1NOTE10.2.1.4
3、 was editorially corrected in March 2018.1. Scope*1.1 This specification covers poly(vinyl chloride) (PVC)pipe made in Schedule 40, 80, and 120 sizes and pressure-ratedfor water (see Appendix X1). Included are criteria for classi-fying PVC plastic pipe materials and PVC plastic pipe, asystem of nome
4、nclature for PVC plastic pipe, and requirementsand test methods for materials, workmanship, dimensions,sustained pressure, burst pressure, flattening, and extrusionquality. Methods of marking are also given.1.2 The products covered by this specification are intendedfor use with the distribution of p
5、ressurized liquids only, whichare chemically compatible with the piping materials. Due toinherent hazards associated with testing components and sys-tems with compressed air or other compressed gases somemanufacturers do not allow pneumatic testing of their products.Consult with specific product/com
6、ponent manufacturers fortheir specific testing procedures prior to pneumatic testing.NOTE 1Pressurized (compressed) air or other compressed gasescontain large amounts of stored energy which present serious safteyhazards should a system fail for any reason.NOTE 2This standard specifies dimensional, p
7、erformance and testrequirements for plumbing and fluid handling applications only. It doesnot include provisions for the use of these products for venting ofcombustion gases. UL 1738 is a standard that does include specific testingand marking requirements for flue gas venting products, including PVC
8、.1.3 The text of this specification references notes, footnotes,and appendixes which provide explanatory material. Thesenotes and footnotes (excluding those in tables and figures) shallnot be considered as requirements of the specification.1.4 The values stated in inch-pound units are to be regarded
9、as standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.5 The following safety hazards caveat pertains only to thetest methods portion, Section 8, of this specification: Thisstandard does not purport
10、 to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety, health, andenvironmental practices and determine the applicability ofregulatory limitations prior to use.A specific precautionarystatement is
11、given in Note 9.NOTE 3CPVC plastic pipes, Schedules 40 and 80, which wereformerly included in this specification, are now covered by SpecificationF441/F441M.NOTE 4The sustained and burst pressure test requirements, and thepressure ratings in the Appendix X1, are calculated from stress valuesobtained
12、 from tests made on pipe 4 in. (100 mm) and smaller. However,tests conducted on pipe as large as 24-in. (600-mm) diameter have shownthese stress values to be valid for larger diameter PVC pipe.NOTE 5PVC pipe made to this specification is often belled for use asline pipe. For details of the solvent c
