T4-03 BALL PRESSURE TEST APPARATUS

It is intended for testing parts of non-metallic materials for resistance to heat. It is applicable to electrotechnical equipment, its subassemblies and components, and to solid electrical insulating materials except ceramics. It is 5 mm hardened steel ball with weights that exert a force of 20 N on the surface of tested sample. A suitable support for tested sample is also enclosed. The test sample shall be positioned on the support, heated up in an oven and than loaded with ball pressure test apparatus. After required period, the sample is taken out of chamber, immersed in cold water and then indentation is measured. In some cases this test is long, or multiple samples shall be checked, therefore in such cases it is practical to test multiple samples at the same time – so more than one apparatus might be needed for parallel testing.
