A thermal shock test chamber is a piece of equipment designed to perform thermal shock tests. The typical thermal shock test chamber comprises three main components: the test chamber, the control system and the cooling/heating system. To guarantee the precision and dependability of the test outcomes, it is essential to perform periodic calibration of the thermal shock test chamber. Please find below a description of the calibration specifications for a thermal shock test chamber. 1. Calibration frequency The calibration frequency of the thermal shock test chamber should be determined according to its intended use and production process. It is recommended that the calibration frequency be not less than once a year, or before the equipment is used for important tests. 2. Calibration standards The calibration of the thermal shock test chamber should be carried out in accordance with the relevant standards, such as ISO 9001, ASTM D3580, GB/T 2423 and so on. Calibration standards must guarantee the accuracy and reliability of test results, as well as the stability and consistency of the equipment. 3. Calibration Procedure The calibration procedure for the thermal shock test chamber shall include the following steps: (1) Equipment inspection: It is important to ensure that the equipment is in good working order, with all its components, including the appearance, electrical and mechanical parts, functioning properly. (2) Temperature calibration: It is important to ensure that the equipment's temperature control system is functioning correctly. This can be done by calibrating thermocouples or temperature sensors. (3) Humidity calibration: It is important to check the accuracy of the equipment's humidity control system by calibrating the humidity sensor. (4) Test chamber uniformity calibration: This is to be carried out to ascertain whether the temperature and humidity distribution in the test chamber is uniform. This is to be done by placing temperature and humidity sensors

Main role of battery temperature cycling test chamber: (1) Evaluate the thermal stability of the battery: By simulating the working conditions of the battery in different temperature environments, the thermal stability of the battery can be evaluated at high, low or even extreme temperatures. This is crucial for the safety and reliability assessment of the battery. (2) Simulate the temperature cycle of the battery in actual use. The battery will experience temperature rise and fall in the course of use, which has a certain impact on the performance and life of the battery. The battery temperature cycling test chamber enables the temperature changes of the battery in actual use to be simulated, thus allow

Difference between salt spray test chamber and composite salt spray test chamber The composite salt spray test chamber is a widely used device for testing the corrosion resistance of materials and components. Its scope of application is very wide, including automotive, aviation, electronics, shipping, chemical industry, military industry and other fields. The power level of the salt spray test chamber is an important factor affecting its function, which depends on a variety of factors. What is the difference between a salt spray test chamber and a compound salt spray test chamber? The following ring instrument will be interpreted for you: the general salt spray box is said to carry out NSS neutralised salt spray test, ASS acetate spray test, CASS copper accelerated acetate spray test, while the composite salt spray test box is usually specified with the ambient humidity manipulation of the box. The key is to do corrosion resistance, cold and wet alternating changes in the experiments, dry and agitated, cold suspicion, self-spraying and other roles. The composite salt spray test box for artificial service climate natural environment "cold and humidity, anti-corrosion, anti-yellowing mould" experimental equipment is one of the scientific research machinery and equipment, national defence science and technology, light industry, electronic devices, instrument panels and other manufacturing industries. It is a key experimental equipment with a variety of natural environment adaptability and credibility. Please find below the specification for the composite salt spray test chamber. 1.

Vehicle Rain Test The field of water management is concerned with the direction of water, the sealing performance of water, the path of water in the whole vehicle, and the waterproof characteristics of the parts at the boundary of the water path. It is a key index of automotive performance development and a factor that customers can directly perceive. As a result, water management is becoming increasingly important to OEMs. The challenge of enhancing the development capability of automotive water management and circumventing quality issues in this domain is a significant hurdle for OEMs. Vehicle rainfall represents a crucial quality indicator. During the manufacturing process, automobiles may exhibit local rain leakage issues due to inadequate pre-design of parts, deficiencies in quality control of parts, and deviations in manufacturing process parameters, among other factors. Additionally, through rain leakage validation, automobiles can effectively avoid water leakage issues. Consequently, through rain leakage verification, it is possible to comprehensively examine the vehicle design, parts quality, manufacturing process and other modules with regard to their level and process consistency. The quality of the vehicle water leakage is not only related to customer experience, but also part of the problem may affect the life of the whole vehicle and customer safety. Consequently, the mastery of the detection method, analysis method, and causes of common problems of the whole vehicle water leakage can effectively avoid the risk of water leakage, improve product quality, and reduce customer complaints. 1. Vehicle rain test and detection 1.1. Classification of water leakage problems The severity of a water leakage problem can be classified into three categories: seepage, dripping, and flowing. The evaluation basis for these categories can generally be found in the following standards: Seepage: water appears slowly from the gaps and diffuses along the inner surface
