38、2.NOTE 7Before installing a CPVC chemical waste piping system,chemical resistance data for the piping in question should be evaluated.Caution should be taken when mixing chemicals as properties can change.If there is a chemical resistance question, consult the manufacturer(s).8. Test Methods8.1 Cond
39、itioning:8.1.1 For routine quality control testing, condition the speci-mens at the room temperature and humidity of the manufac-turers testing facilities for not less than one hour or until thespecimens reach room temperature.8.1.2 For referee purposes, condition and test the specimensbefore testin
40、g, in a standard laboratory atmosphere of 73.4 63.6F (23 6 2C) and 50 6 5% relative humidity for not lessthan 40 hours prior to testing in accordance with Procedure Aof Practice D 618.8.2 CPVC Compound Chemical ResistancePipe and fit-ting materials shall be evaluated in accordance with TestMethod D
41、543 practice A, procedures I and II, using thechemicals listed in Table 4. Weight change shall not exceed 2%nor shall apparent tensile strength change by more than 10 %.In cases where there is a change in the apparent tensile strengthgreater than 10%. In cases where there is a change in theapparent
42、tensile strength greater than 10%, a further evaluationshall be made after the test specimen is removed from thechemical and conditioned for 72 h. If after 72 h, there is aminimum of 50% recovery of tensile strength as compared tothe unexposed specimen, and that figure is within 610% of theoriginal
43、tensile strength of the unexposed specimen, the testshall be considered acceptable.8.3 Solvent Cement Joint Chemical Resistance IntegrityTestPrepare ten pipe test specimens, each having two sec-tions of pipe connected by a coupling using the manufacturersspecified solvent cement that is used to join
44、 the CPVCchemical waste drainage systems. The ten pipe test specimensshall be fitted with test caps on both ends with drain and ventconnections to enable the specimens to be filled with chemicalsand to subsequently be internally pressurized. Allow thematerials to be conditioned at 73.4 6 3.6F (23 6
45、2C) for 24h after the joints are completed. After the 24 h conditioningperiod, completely fill each of the ten specimens with thechemicals listed in Table 4. One chemical at the specifiedconcentrations within Table 4 shall be used per test specimen,making sure that the chemical media completely fill
46、s thespecimen prior to being capped off. The specimens shall bepre-labeled to identify with which of the chemicals it is filled.Expose each of the ten specimens to the chemicals for oneweek at 73.4 6 3.6F (23 6 2C) under an internal testpressure of 5 psig (34.5 kPa). After the holding period, remove
47、the specimens and drain the chemical reagents. The specimensshall be rinsed and dried to remove any traces of the chemicalsfrom the inside of the pipe. Each specimen shall then besubjected to a hydrostatic test pressure of a minimum of 50psig (345 kPa) at 73.4 6 3.6F (23 6 2C) for a minimumduration
48、of 5 min. The pressure test must be completed within24 h after the specimens have been drained and cleaned.8.4 Solvent Cemented Joint Hydrostatic Pressure TestSelect at random six specimens of pipe, each five times thenominal diameter or a maximum of 18 in. (450 mm) in length,for each size of piping
49、 and each type of system beingconsidered.
