Designation:D1599141Standard Test Method forResistance to Short-Time Hydraulic Pressure of PlasticPipe,Tubing,and Fittings1This standard is issued under the fixed designation D1599;the number immediately following the designation indicates the year oforiginal adoption or,in the 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.1NOTE8.1 was editorially corrected in April 2015.1.Scope*1.1 This test method covers the determination of the resis-tance of either thermoplastic or reinforced thermosetting resinpipe,tubing,or fittings to hydraulic pressure in a short timeperiod.Procedure A is used to determine burst pressure of aspecimen if the mode of failure is to be determined.ProcedureB is used to determine that a specimen complies with aminimum burst requirement.1.2 This test method is suitable for establishing laboratorytesting requirements for quality control purposes or for pro-curement specifications.1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of whoever uses this standard to consult andestablish appropriate safety and health practices and deter-mine the applicability of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2D2122 Test Method for Determining Dimensions of Ther-moplastic Pipe and FittingsD3517 Specificationfor“Fiberglass”(Glass-Fiber-Reinforced Thermosetting-Resin)Pressure PipeD3567 Practice for Determining Dimensions of“Fiberglass”(Glass-Fiber-Reinforced Thermosetting Resin)Pipe andFittings3.Summary of Test Method3.1 This test method consists of loading a specimen tofailure,or a predetermined minimum level,in short-timeinterval by means of continuously increasing internalhydraulic-pressure while immersed in a controlled-temperatureenvironment.4.Significance and Use4.1 This test method establishes the short-time hydraulicfailure pressure of thermoplastic or reinforced thermosettingresin pipe,tubing,or fittings.Data obtained by this test methodare of use only in predicting the behavior of pipe,tubing,andfittings under conditions of temperature,time,method ofloading,and hoop stress similar to those used in the actual test.They are generally not indicative of the long-term strength ofthermoplastic or reinforced thermosetting resin pipe,tubing,and fittings.4.2 Procurement specifications utilizing this test methodmay stipulate a minimum and maximum time for failure otherthan the 60 to 70 s listed in 9.1.3.Either the internal hydraulicpressure or the hoop stress may be listed in the requirements.NOTE1Many thermoplastics give significantly different burststrengths depending on the time to failure.For instance,significantdifferences have been observed between failure times of 65 and 85 s.4.3 This test method is also used as a short-term pressur-ization validation procedure,where the specimens are pressur-ized to a predetermined minimum pressure requirement.5.Failure5.1 Any instantaneous or rapid loss of pressure shall con-stitute failure.5.2 Any visible passage of fluid through the wall of thespecimen shall constitute failure.5.3 Any loss of pressure that interrupts the continuous anduniform pressure increase,described in 9.1.3,shall constitutefailure.1This test method is under the jurisdiction of ASTM Committee F17 on PlasticPiping Systems and is the direct responsibility of Subcommittee F17.40 on TestMethods.Current edition approved April 15,2014.Published November 2014.Originallyapproved in 1962.Last previous edition approved in 2011 as D1599 99(2011).DOI:10.1520/D1599-14E01.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.*A Summary of Changes section appears at the end of this standardCopyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 5.4 Leakage at the end closure or fracture of the specimen inthe immediate vicinity of the end closure shall be considered asan invalid test item,not a failure.6.Apparatus6.1 Constant-Temperature BathAwater bath or other fluidbath equipped so that uniform temperature is maintainedthroughout the bath.This may require agitation.If an air orother gaseous environment is used,provisions shall be madefor adequate circulation.Unless otherwise stated,the tests shallbe conducted at 736 3.6F(23 6 2C).The tolerance on othertest temperatures shall be 3.6F(6 2C).Fluid environmentsthat chemically at
