Plastics - Determination of temperature of deflection under load - Part 1: General test method
The principle of the method specified is subjecting a standard test specimen to a bending stress under three-point loading to produce one of the nominal surface stresses in the relevant part of this standard, raising the temperature at a uniform rate, measuring the temperature, at which a specified deflection occurs. The results obtained do not necessarily represent maximum use temperatures.
