9、ion, Section 8, of this specification: Thisstandard does not purport 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 and healthpractices and determine the applicability of regulatory limita-ti

A specific precautionary statement is givenin Note 7.NOTE 3CPVC plastic pipe (SDR-PR), which was formerly includedin this specification, is now covered by Specification F442/F442M.NOTE 4The sustained and burst pressure test requirements, and thepressure ratings in the appendix, are

11、 calculated from stress values obtainedfrom tests made on pipe 4 in. (100 mm) and smaller. However, testsconducted on pipe as large as 24 in. (600 mm) in 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

Terminology

20、3.1 DefinitionsDefinitions are in accordance with Termi-nology F412, and abbreviations are in accordance with Termi-nology D1600, unless otherwise specified.The abbreviation forpoly(vinyl chloride) plastic is PVC.3.2 Definitions of Terms Specific to This Standard:3.2.1 hydrostatic design stressthe e

21、stimated maximumtensile stress the material is capable of withstanding continu-ously with a high degree of certainty that failure of the pipewill not occur. This stress is circumferential when internalhydrostatic water pressure is applied.3.2.2 pressure rating (PR)the estimated maximum waterpressure

22、 the pipe is capable of withstanding continuously witha high degree of certainty that failure of the pipe will not occur.3.2.3 relation between standard dimension ratio, hydro-static design stress, and pressure ratingThe following ex-pression, commonly known as the ISO equation,4is used inthis speci

23、fication to relate standard dimension ratio, hydrostaticdesign stress, and pressure rating:2S/P 5 R 2 1 or 2 S/P 5 D0/t! 2 1 (1)where:S = hydrostatic design stress, psi (or MPa),P = pressure rating, psi (or MPa),D0= average outside diameter, in. (or mm),t = minimum wall thickness, in. (or mm), andR

24、= standard thermoplastic pipe dimension ratio (D0/t forPVC pipe), also known as SDR.3.2.4 standard thermoplastic pipe dimension ratio (SDR)the ratio of pipe diameter to wall thickness. For PVC pipe it iscalculated by dividing the average outside diameter of the pipein inches or millimetres by the mi

25、nimum wall thickness ininches or millimetres. If the wall thickness calculated by thisformula is less than 0.060 in. (1.52 mm), it shall be arbitrarilyincreased to 0.060in. (1.52 mm). The SDR values shall berounded to the nearest 0.5.3.2.5 standard thermoplastic pipe materials designationcodeThe pip

26、e materials designation code shall consist of theabbreviation PVC for the type of plastic, followed by theASTM type and grade inArabic numerals and the design stressin units of 100 psi (0.7 MPa) with any decimal figures dropped.When the design stress code contains less than two figures, acipher shal

27、l be used before the number, thus a completematerial code shall consist of three letters and four figures forPVC plastic pipe materials.4.
