VICAT
SOFTENING TEMP. (ASTM D1525)
:
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
DEFLECTION TEMPERATURE OF PLASTIC UNDER
FLEXURAL LOAD ( As per ASTM D-648)
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.
