Ball Pressure Test Apparatus
|The ball pressure test apparatus is used to check the integrity of dielectric material with respect to resistance to elevated operating temperature. The ball pressure test is referred in IEC 60335, IEC 60695, IEC 60950, IEC 61010, is 302, is 1293, is 3854, is 2215, bs, ul, csa and European norms. The scr elektroniks make ball pressure test apparatus model bp 21 takes care of this testing useful for insulator manufacturers and other electro-technical manufacturers who use insulating material in their electrical appliances. The bp 21 is made of stainless steel for long life and exerts a force of 20 newton on the unit under test. |
As described by popular standards, the unit under test is placed on a platform and the ball pressure test apparatus is placed on top of it. The whole assembly is then placed inside an oven and the temperature inside the oven is maintained at certain temperature for certain time as specified by the applicable standard. After the test time, the ball pressure test apparatus along with the unit under test is removed from the oven and the unit under test is allowed to return to ambient temperature. The depression created by the ball pressure test apparatus in the unit under test (due to softening) is measured. If the diameter of the impression is not greater than certain value (specified by the relevant standard), the unit under test is said to comply with the standard.
1. All stainless steel construction.
2. Magnifier with built-in scale for measuring the depression created by the ball pressure test apparatus.
3. Supplied in a compact and neat carrying case.
4. Precision engineered and manufactured for ball pressure test covering all popular standards.
