The cold and hot impact testing machine is a commonly used material testing equipment used to evaluate the durability performance of materials under temperature changes. This article will provide a detailed introduction around this issue, exploring the technical parameters and testing standards of cold and hot impact testing machines.

The technical parameters of the cold and hot impact testing machine include the following aspects:

(1) Temperature range: The cold and hot impact testing machine should be able to provide a wide temperature range to meet the testing needs of different materials. Generally speaking, the temperature range should be between -70 ℃ and+150 ℃.

(2) Temperature control accuracy: The temperature control accuracy of the cold and hot impact testing machine should reach a high level to ensure the accuracy of the test results. Generally speaking, the temperature control accuracy should be within ± 1 ℃.

(3) Sample size: The cold and hot impact testing machine should be able to accommodate samples of different sizes to meet the testing needs of different materials.

(4) Test method: The test methods of the cold and hot impact testing machine include unidirectional impact, bidirectional impact, and circular impact, etc. The appropriate test method should be selected based on the testing needs of different materials.

(5) Test time: The test time of the cold and hot impact testing machine should be determined based on the testing needs of different materials. Generally speaking, the test time should be between tens of minutes and several hours.

The following are some common test standards for cold and hot impact testing machines:
