GB/T 32065.4-2015Environmental test methods for oceanographic instruments - Part 4: Dry heat (English PDF)

3.1 General requirements

Marine Instruments standard atmospheric conditions of high temperature test, the test sample installation, test temperature stability test should be separately according to the interrupt handling

The provisions of GB/T 32065.1-2015 in 4.2,6.1,6.2 and Chapter 7 will be.

3.2 Test equipment and test preparation

3.2.1

Test equipment shall comply with GB/T 32065.1-2015 in Chapter 5.

3.2.2

test, the test sample should be as close to the central chamber (chamber), which corresponds to any surface with the chamber (chamber) intramural

The minimum distance should be greater than 15cm, and the chamber (chamber) in the wind speed should not exceed 1.7m/s.

3.2.3

If the frame or the connecting member is installed along with the test sample test, the test sample volume should be included in the volume. When a plurality of test samples

When starting the test, ensure that the test sample does not interfere with each other.

3.2.4

Test sample chamber (chamber) should be free from any direct radiation heating and cooling elements.

Water vapor (chamber) inside the chamber 3.2.5 does not exceed 20g/m3 (equivalent to 35 °C, 50% relative humidity). When the test temperature is below

35 °C, relative humidity should not exceed 50%.

3.3 Test temperature

Unless otherwise specified, the ocean temperature heat test equipment should be selected with the following provisions.

a) (40 ± 2) °C;

b) (50 ± 2) °C;

c) (60 ± 2) °C;

d) marine instrumentation highest temperature environment.

3.4 Duration

After the temperature test sample to achieve sustained stable for at least 2h, or by the relevant specifications (for example. product standards, test program or test contracts, […]
