Cold and hot impact tests are usually used to test the durability and stability of products or materials such as electronic equipment, automotive components, and building materials. Through this type of testing, the performance and reliability of products or materials can be evaluated to ensure that they can work properly in various environments and withstand long-term use and temperature changes. When conducting cold and hot impact testing, it is necessary to select appropriate testing parameters based on the testing purpose and sample characteristics.

The parameter standards for cold and hot impact tests are usually developed by the International Organization for Standardization (ISO) and other industry organizations. The following are some common cold and hot impact test parameter standards:

1. Temperature range: Cold and hot impact tests are usually conducted between -40 ° C and+150 ° C, but sometimes more extreme tests are conducted, such as -70 ° C to+200 ° C.

2. Exposure time: The tested product or material is usually exposed to high or low temperatures for several minutes or hours, and then quickly transferred to another extreme temperature for exposure. This process will be repeated multiple times until the required testing time is reached or until the product or material malfunctions.

3. Conversion time: Conversion time refers to the time from one extreme temperature to another extreme temperature. Usually, the conversion time should be as short as possible to ensure the accuracy of the test results.

4. Exposure frequency: Cold and hot impact tests usually need to be conducted multiple times to simulate temperature changes and impacts during long-term use. Usually, the number of tests should be sufficient to ensure the reliability and durability of the product or material.

5. Exposure temperature difference: Exposure temperature difference refers to the temperature difference between one extreme temperature and another extreme temperature. Usually, the temperature difference should be large enough to ensure the accuracy of the test results.

6. Test standards: The standards for cold and hot impact testing are usually formulated by the International Organization for Standardization (ISO) or other industry organizations, such as ASTM, IEC, JIS, etc. These standards specify the methods, parameters, and evaluation methods of testing results to ensure the reliability and accuracy of testing results.
