Purpose of this section is a predetermined constant for determining the temperature within the time, the influence of non-condensing humidity environment test sample. This section applies to small devices or elements, are also suitable for larger devices, apply to both heat and non-heat test sample. 2 Normative references
The following documents for the application of this document is essential. For dated references, only applies to the version dated paper Pieces. For undated references, the latest edition (including any amendments) applies to this document. IEC 60068-1 Environmental testing - Part 1. Overview and guidance (Environmental testing-Part 1. General and guidance) 3 Terms and Definitions
4 Test Overview
4.1 chamber and measurement systems
Temperature/humidity chamber should be required to be installed to confirm IEC 60068-3-6. Chamber and measurement systems shall be as follows.
--- sensors should be mounted in the working space of the chamber to monitor the temperature/humidity; NOTE. For heat test sample, the test sample affects the cooling temperature and humidity near the test sample position. --- chamber condensate discharge chamber should be continuous, if not discharged condensate purification can not be reused; Condensate --- the inner wall of the chamber and the top should not drip on the test sample; --- water conductivity humidity in the test chamber should be kept not more than 20μS/cm; --- Test of the test sample should not be subject to direct heat radiation of the air conditioner; --- The spray system of the test chamber, the test sample should be away from the injection port, and the moisture is not directly projected onto the sample; --- volume of the chamber is at least five times the volume of the test sample; Unless otherwise specified in the relevant specification --- When using mounting bracket, with minimal impact to deal with temperature and humidity exchange between the test sample and the surrounding environment. 4.2 severities
The severity of the test temperature, relative humidity, together determine the duration of the test. Unless the relevant specification, and the temperature of the test phase Humidity should be selected in Table 1.
Table 1 Temperature and relative humidity
temperature
Relative humidity RH
30 ± 2 93 ± 3
30 ± 2 85 ± 3
40 ± 2 93 ± 3
40 ± 2 85 ± 3
Recommended duration. 12h, 16h, 24h and 2d, 4d, 10d, 21d or 56d.
The total temperature tolerance of ± 2K absolute error is taken into account, the temperature gradient and the temperature in the working space during testing. In order to maintain The relative humidity of the test chamber within a predetermined tolerance range must be maintained between any two points in the test chamber to make the temperature difference at any time As small as possible. If the temperature difference over 1K, then can not achieve the desired humidity. Short-term temperature fluctuations must be maintained in the range ± 0.5K In order to maintain the desired humidity conditions.
4.3 Pretreatment
Related specifications may require pretreatment.
4.4 Test Conditions
Test samples should be placed in the relevant norms required chamber. Unless otherwise specified, it should be no packaging, no power, "ready to use" shape State test sample was placed in a test chamber.
In particular, when the relevant specifications may allow test sample was placed in the test chamber reached test conditions, and should be avoided samples produced condensate Lu, for small samples can be achieved by preheating the request.
Adjusting the temperature of the test chamber and arriving at the desired severity. In order to avoid condensation generated test sample, the test sample should be temperature controlled Or the test sample reaches the test temperature was adjusted to a relative humidity chamber reaches a predetermined value. Within 2h, the tank by adjusting the humidity reaches the predetermined test severity. The relevant specification shall specify the duration of the test conditions and test. To start the test duration should test conditions reaches a predetermined value Calculation.
Related specifications should provide test samples taken during the test chamber conditions and duration. After the test conditions, before the last test, the test procedures shall provide for the recovery. 4.5 recovery
The relevant specification shall specify the methods and recovery time. Restore the conditions as specified in IEC 60068-1 requirements. 5 Detection
5.1 Initial Detection
According to the specification, visual inspection of the test sample, detecting its electrical and mechanical properties. 5.2 intermediate detector
The relevant specification can be made at the end of the period or conditions for testing test samples remain in the test chamber for testing, if the need for this When the species is detected, the relevant specification shall prescribe testing and project completion time of these tests. When this detection is performed, the test sample should be taken Outside the box.
5.3 final inspection
According to the specification, the appearance of the test sample was examined to detect its electrical and mechanical properties. 6 specifications related information should be given
