T4‑03 BALL PRESSURE TEST APPARATUS is designed and manufactured in compliance with IEC 60695-10-2, 60335-1, 60950-1, 60884-1, 60320-1, 60598-1, 61010, 61032, 60439-5, IEC 60601-1, BS 1363-1, IRAM 2073, 4220-1 NM, BIS, UL 2601-1, CSA 60745, VDE, BSI, DIN, EN.
T4-03 BALL PRESSURE TEST APPARATUS is intended for testing parts of non-metallic materials for resistance to heat. It is applicable to electrotechnical equipment, its subassemblies and components, and solid electrical insulating materials except for ceramics. It is a 5 mm hardened steel ball with weights that exert a force of 20 N on the surface of a tested sample. Suitable support for the tested sample is also enclosed. The test sample shall be positioned on the support, heated up in an oven and then loaded with a ball pressure test apparatus. After the required period, the sample is taken out of the 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.
The ball part is engraved with catalog number and serial number, to enable its traceability and certification
