Hot Set Tester - For Testing Lab
Many important properties of polyethylene insulation of cables depend
on the degree to which the material is cross-linked. Determination of
whether or not the dependent properties are fully realized after
cross-linking can be carried out with the help of a hot set test.
In
this test the elongation of the insulating material at an elevated
temperature under the action of a specified tensile load and its
recovery after removal of the load are determined to evaluate the
efficiency of the cross-linking. A dumbbell of specified shape and size
is suspended from a vertical frame inside a hot air oven with a
specified load suspended from its lower end. The elongation of the test
specimen after fifteen minutes under the above conditions and its
subsequent recovery after removal of the load are then evaluated.
