(Test Method)Standard Test Method for Adequacy of Fusion of Extruded Poly(Vinyl Chloride) (PVC) Pipe and Molded Fittings by Acetone Immersion
Standard Test Method for Adequacy of Fusion of Extruded Poly(Vinyl Chloride) (PVC) Pipe and Molded Fittings by Acetone Immersion
SIGNIFICANCE AND USE
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 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 only detects inadequate fusion and does not determine the over-all quality of the PVC pipe or fittings.
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.
This test method is useful in evaluating the adequacy of PVC fusion obtained in process or materials trials.
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 and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Annex A1.

D2152–95 (2010)
5.2 Prior to conducting the test, check the density of the acetone with a precision hydrometer to determine its dryness. If the
density of the acetone is greater than 0.7890 g/mLat 23°C, (corresponding to approximately 1% water by mass (see Fig. X1.1)),
use fresh acetone or dry the wet acetone with a drying agent. Recheck the density of the fresh or dried acetone before using.
NOTE 2—Wet acetone can be dried by thoroughly agitating it with at least 15 g of anhydrous calcium sulfate (CaSO ) for each gram of water present.
NOTE 3—The presence of water in the acetone reduces its sensitivity to differences in the degree of fusion of rigid poly(vinyl chloride) (PVC). It is
important to dry the acetone properly and conduct the test in a sealed container, because acetone rapidly absorbs moisture from the atmosphere.
NOTE 4—Round-robin testing between four laboratories showed that test results are not significantly altered with up to 2% water by weight in the
acetone.
6. Sampling
6.1 Specimens shall be taken from individual pipe sections, fittings, or remnant portions of pipe or fittings. Specimens shall be
taken from locations which are to be evaluated for adequacy of fusion, or immediately adjacent to them.
6.2 The number of individual specimens to be tested and their locations shall be chosen to be representative of the pipe or
fittings being evaluated for adequacy of fusion.
