In the late 1950s and early 1960s, inadequate fusion of PVC materials was a relatively frequent occurrence for North American PVC pipe manufacturers. As a result, an acetone-immersion test method was developed and published in 1963 as ASTM D2152 “Standard Test Method for Adequacy of Fusion of Extruded Poly(Vinyl Chlo-ride) (PVC) Pipe and Molded Fittings by Acetone Immersion.”
Over the years, PVC pipe extrusion machinery and materials became more sophisticated. As a result, inadequate fusion occurred infrequently and failure rates of acetone tests dropped to near zero. Manufacturers also realized that other quality tests (such as impact and flattening tests) were identifying the occasional fusion problem that did occur.
Another complication arose in the 1980s: acetone, once considered a relatively harmless chemical, was determined to be a health and safety hazard and a toxic waste. Strict government regulations were imposed on the storage, use, and disposal of ace-tone.
This paper will show that the acetone-immersion test is severely limited in its usefulness due to its application and to the properties of the substance itself.
