C Bibliography

Describes the preparation of test specimens and provides test methods to define characteristics of thermoplastic fluoropolymer resins. Describes the conditions of test for determining both designatory and other properties of the homopolymers and various copolymers of fluoromonomers, as dispersions or powders for moulding, extrusion, and other uses.
