Scientists atthat time found the new plastic material unusual in that it appeared nearly inert tomost chemicals.

In Europe and America, extended efforts eventually brought PVC plastics to themodern world. Technology, worldwide and particularly in Germany, slowly evolved forthe use of PVC in its unplasticized, rigid form, which today is used in the production ofa great many extruded and molded products.
AWWA’s PVC pipe and fittings standards define the basic properties of PVC com-pound, using the American Society for Testing and Materials (ASTM) Specification D1784, Standard Specification for Rigid Poly (Vinyl Chloride) (PVC) Compounds and Chlorinated Poly (Vinyl Chloride) (CPVC) Compounds. The specification includes a
