Determination of the temperature at which a standard indenter penetrates 1mm into the surface of a plastics test specimen under one of the loads specified under uniform rate of heating.
Rate of rise of temp. 50 + 50C / per hr. 120 + 120C
Determination of temp. at which an arbitrary deformation occurs when plastics are subjected to arbitrary bending loads and conditions of continually rising temperature Rate of rise of temp. 2 + 0.20C / per min
