ASTM D2152-23(Test Method)
Standard Test Method for Adequacy of Fusion of Extruded Poly(Vinyl Chloride) (PVC) Pipe and Molded Fittings by Acetone Immersion

SIGNIFICANCE AND USE
3.1 This test method is applicable only for distinguishing between inadequately fused and adequately fused PVC. The difference between thermally degraded and adequately fused PVC cannot be detected by this test method. Acetone immersion testing is not a substitute for burst, impact, or other physical or chemical tests on PVC pipe or fittings and it, therefore, shall not be used as the only test specification for purchasing of PVC pipe and fittings. This test method only detects inadequate fusion and does not determine the over-all quality of the PVC pipe or fittings.  
3.2 This test method is useful in determining whether inadequate fusion contributed to failure of PVC pipe or fittings in other physical or chemical tests, or in service.  
3.3 This test method is useful in evaluating the adequacy of PVC fusion obtained in process or materials trials.  
3.4 This test method determines adequacy of fusion on a single, relatively small specimen. This test method requires the use of a hazardous reagent which must be properly handled and disposed. Therefore, this test method may not be cost-effective to employ as a routine quality control test.
SCOPE
1.1 This test method covers the determination of the adequacy of fusion of extruded rigid poly(vinyl chloride) (PVC) pipe and molded fittings as indicated by reaction to immersion in anhydrous acetone.  
1.2 The values stated in inch-pound units are to be regarded as the standard except where instruments are calibrated in SI units.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.Specific hazards statements are given in Annex A1.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
