Heat-resistant electrical insulating materials Part 6. Ageing ovens - Multi-chamber ovens

1 Scope

GB/T 11026 provisions of this section, including an electrically insulating material with a heat resistance of assessment or other appropriate thermal conditioning applications (NA Single Chamber oven aging) heat aging for evaluation of a multi-chamber of the basic requirements of ventilation and heating oven.

This section applies to the oven until the 20K increase in the ratio of 500 °C ambient temperature of the whole or part of the operating temperature range.

This section also presents the aging oven containing the sample under the conditions and do not install the sample for acceptance testing and performance monitoring tests.

3 Terms and Definitions

The following terms and definitions apply to this section.

Exhaust rate rateofventilation Oven temperature aging chamber hour exposure to air replacement amount under. Air flow rate calculations to work with the inner volume of intersecting planes exposure chamber the cross-sectional area of \u200b\u200bthe subject, and assuming a one-way air flow.

Exposure volume Aging inside the oven (when the cartridge using iso, iso box also refers) to the effective sample is placed in the space.

Exposure temperature (see "Integrated temperature exposure") exposuretemperature (seealsoglobalexposuretemperature) Effects obtained when determining the temperature of the sample and the standard aging test, a sample of the aging temperature selected.

Temperature fluctuations temperaturefluctuation the maximum exposure to changes in the volume of a point temperature occur within 3h time.

Temperature difference the maximum temperature difference between any two points at any time between the volume.
