17、mps, undissolved resin, or any foreign matter that will adverselyaffect the ultimate joint strength or chemical resistance of the cement.4.4 The cement shall show no gelation or stratification that cannot be removed by stirring.4.5 When inert fillers and colorants are added, the resulting cement sha
18、ll meet all requirements of this specification.NOTE 1It is recommended that CPVC solvent cement be orange in color to facilitate identification and minimize unintentional use of other cementsthat may fail at elevated service temperatures.4.6 The particular solvent system to be used in the formulatio
19、n of this solvent cement is not specified, since it is recognized thata number of adequate solvent systems for CPVC exist. Solvent systems consisting of blends of tetrahydrofuran and cyclohexanonehave been found to make cements that meet the requirements of this specification.5. Detail Requirements5
20、.1 Resin ContentThe CPVC resin content shall be 10 % minimum when tested in accordance with 6.1.5.2 DissolutionThe cement shall be capable of dissolving an additional 3 % by weight of CPVC 41 compound (either powderor granular) or equivalent CPVC resin at 73 6 3.6F (23 6 2C) without evidence of gela
21、tion.5.3 ViscosityCements are classified as regular-, medium-, or heavy-bodied types, based on their minimum viscosity whentested in accordance with 6.2.5.3.1 Regular-bodied cements shall have a minimum viscosity of 90 cP (90 MPas).5.3.2 Medium-bodied cements shall have a minimum viscosity of 500 cP
22、 (500 MPas).5.3.3 Heavy-bodied cements shall have a minimum viscosity of 1600 cP (1600 MPas).NOTE 2Refer to Appendix X2 for guidelines in selecting CPVC solvent cements for joining different pipe sizes.5.4 Shelf StabilityThe cement, in the container in which it is supplied, shall show no gelation or
