Apparatus for Checking Mechanical Withstanding of Insulating Materials in Thin Sheet Layers

Apparatus for checking mechanical withstanding of insulating materials in thin sheet layers

Product details: Model ZLT-BM1.

This test is conforms to IEC60558-1 Fig6 and IEC60065 Fig14--16.The test shall be performed by fixing the specimens of thin sheets on a mandrel made of nickel plated steel or brass with smooth surface finish.

A metal foil shall be placed closely to the surface of the specimen and subjected to a pull force of 1 N. The metal foil shall be so positioned that its borders are 20 mm away from the borders of the specimen, and when the mandrel is in its final position, it covers the edges upon which the specimen is lying by at least 10 mm.

the specimen is held in place at its free end by an appropriate clamping device and subjected to:

– a pull force of 150 N for a specimen consisting of several non separable layers;

– a pull force of 100 N for a specimen consisting of 2/3 the number of separated layers

(serrated or not);and 

–  a pull force of 50 N for a specimen consisting of a single layer (serrated or not).

Include:weight:100N*1 and 50N*1.
