3. Test conditions
3.1 Requirements for test equipment
3.1.1 The test box (room) should be able to provide the temperature specified in Chapter 2 of this standard in its working space, with an allowable error of ±2°C. The instrument should not be directly radiated by any heating and cooling elements. 3.1.2 The volume of the test box (room) should be greater than 3 times the volume of the instrument. 4 Test method
4.1 Pretreatment
Put the instrument in normal (or reference) environmental conditions to achieve temperature equilibrium. 4.2 Test
Put the instrument in the test box (room), then lower the temperature of the test box (room) to the specified value at an average temperature change rate of less than 1℃/min, and keep it for 8h.
4.3 Recovery
After the test, the instrument remains in the test box (room), and the temperature of the test box (room) is raised to normal (or reference) environmental conditions at an average temperature change rate of less than 1℃/min, and the recovery time is 8h. 4.4 Final inspection
Inspect the instrument according to relevant standards.
