Ball Pressure Test for Heat Resistance of Non-Metallic Parts

Determines the dimensional stability of non-metallic materials under stress at elevated temperature. A 5 mm hardened steel ball loaded to a constant 20 N is pressed onto the heated test sample, and the resulting indentation is measured to assess how the material deforms under combined heat and load.

Enquiring? Share the material type, test temperature and applicable standard, and we will configure the apparatus accordingly.

Frequently Asked Questions

It checks whether a non-metallic material stays dimensionally stable under a fixed mechanical load at elevated temperature, by measuring how deeply a heated steel ball indents the sample.

The apparatus is built to the ball pressure test requirements of IEC 60335-1 and IEC 60695-10-2, the standards most commonly referenced for heat resistance testing of insulating and polymer parts.

A 5 mm diameter hardened steel ball is pressed onto the sample under a constant force of 20 N.

The sample is positioned on the support, heated in an oven, then loaded with the ball pressure apparatus for the required period. It is then removed, immersed in cold water, and the resulting indentation is measured.

It is widely used on non-metallic parts of plugs, sockets, switches and other electrical accessories, as well as insulating and polymer components used in household appliances.
