Preparation of samples for plastic heat aging test method

The heat aging test box is used for heat aging test of plastic materials (rubber, plastic) electrical insulation and other materials in scientific research units and factories. The GB/T7141-2008 standard is directed to the plastic heat aging test method, in which detailed requirements are made for the preparation of the sample.

1. The quantity and type of samples required shall be in accordance with the relevant national standards for the detection of specific properties, and shall be met at each selected cycle and temperature. At least three parallel samples of each material are exposed at each selected cycle and temperature, unless otherwise specified or agreed upon by all parties.

2. The thickness of the heat aging test chamber sample should be equivalent to, but not greater than, the minimum thickness in the intended application.

3. The sample should be prepared in the same way as in the intended application.

4. All test samples of a series of temperatures should be the same batch.
