High and low temperature test
In natural environment, temperature and humidity are two indivisible natural factors. Due to
different geographical locations in different regions, the temperature and humidity effects
generated are also different. This test is used to confirm the products’ adaptability during storage,
transportation and usage in the climate of some certain temperature and humidity. Severe levels
depend on the high / low temperature, humidity and the time of exposure.
Detailed description of High and low temperature test: this trail is used to confirm the products’
adaptability during storage, transportation and usage in the high temperature and humidity climate.
Severe levels depend on the high temperature, humidity and the time of exposure.
Reference standards: GB/T 2423.2, IEC60068-2-2, IEIA 364, MIL-STD-810F, etc..
Low Temperature Test: This test is used to confirm the products’ adaptability of storage,
transportation and usage in the climate of the low temperature and humidity. Severe levels
depend on the low temperature, humidity and the time of exposure.
Reference standards: GB/T 2423.1, IEC60068-2-1, EIA 364, MIL-STD-810F, etc..
Temperature shock test: This test is used to confirm the products’ adaptability during storage,
transportation and usage in the climate of abrupt temperature change. Severe levels depend on
the high/low temperature, dwell time and cycle number. Reference standard: IEC60068-2-14,
GB2423.22, GJB150.5, etc..
High and low temperature test chamber is mainly aimed at the electrical, electronic products,
components, and other materials’ adaptability during storage, transportation and usage in the
high/low temperature.
The test equipment is mainly used for the products in accordance with national standards or user
requirements, in low temperature, high temperature, conditions, the physical and other related
characteristics of the environment simulation testing, testing, to determine the performance of the
product, whether it is still able to meet the predetermined requirements, so as to provide product
design, improvement, identification and factory inspection.
High and low temperature test box to prohibit the test items: 1) Explosive; 2) Combustible;
3)Tinder.
