GB/T 32065.4-2015 Marine instrument environmental test method Part 4.High temperature test
3 Test requirements
3.1 General requirements
The standard atmospheric conditions for the temperature change test of marine instruments are carried out in accordance with the provisions of 4.2 in GB/T 32065.1-2015; the test samples are safe
The installation is carried out in accordance with the provisions of 6.1 in GB/T 32065.1-2015; the test interruption processing is in accordance with the provisions of Chapter 7 in GB/T 32065.1-2015
Regulations proceed.
3.2 Test equipment
3.2.1 The test equipment should comply with the provisions in Chapter 5 of GB/T 32065.1-2015.
3.2.2 The test equipment can be two temperature test chambers (chambers) or a multi-chamber temperature shock test chamber (chamber) meeting the test conditions.
Unless otherwise specified, when the test sample is converted, the temperature in the test box (chamber) should be restored to within 10% of the exposure duration.
Set the temperature.
3.2.3 The relative humidity in the test box (chamber) should not exceed 50%.
3.2.4 During the test, the test sample should be close to the center of the test box (chamber), and the minimum distance between any surface and the wall of the corresponding test box (chamber)
Should be greater than 15cm.
3.2.5 If the mounting frame or connecting piece is tested together with the test sample, its volume should be included in the test sample volume. When multiple test samples
When starting the test, in addition to meeting the requirements of 3.2.4, it should also ensure that the test samples will not interfere with each other.
3.2.6 The test sample should not be directly radiated by any heating and cooling components in the test box (chamber).
3.3 Test severity level
3.3.1 Test temperature
Unless otherwise specified, the temperature change test temperature of marine instruments shall be selected from the following requirements.
