Heat Distortion Temperatures of Plastic Compositions bg Means of a Torsional Test

Using Small Quantities of Material

The standard A.S.T.M. method of test for heat distortion temperature (HDT) of plastics1 requires a relatively large size specimen, 5 X 0.5 X 0.125 to 0.5 in., approximately 15 g. It is common that during the initial stages of a re-' Vinyl chloride compositions stabilized with 1 part basic lead carbonate except where noted.

' Vinyl chloride compositions are given in molar quantities.
