During the development phase, it is used to expose defects in all aspects of the trial product and evaluate the reliability of the product to meet predetermined indicators;
2. Provide information for monitoring the production process during the production phase;
3. Conduct reliability assessment or acceptance of standardized products;
4. Exposure and analysis of product failure patterns and related failure modes and mechanisms under different environmental and stress conditions. Reliability refers to the ability or possibility of components, products, and systems to perform their functions within a certain period of time and under certain conditions. The reliability, failure rate, and average * interval product reliability environmental reliability test is an activity carried out to ensure that the product maintains functional reliability in all expected environments of use, transportation, and storage during its specified lifespan. It is the process of exposing a product to natural or artificial environmental conditions to evaluate its performance under actual use, transportation, and storage conditions, and analyzing the degree of influence and mechanism of environmental factors. By using various environmental testing equipment to simulate high temperature, low temperature, high temperature water humidity, and sudden changes in humidity in the climate environment, the reaction of the product in the usage environment is accelerated to verify whether it meets the expected quality goals in research and development, design, and manufacturing, and to evaluate the overall product to determine its reliability life.
5. The significance of reliability testing in evaluating products should not only be based on their functionality and performance, but also take into account their various conditions, such as the reliability of their functionality and performance in harsh environments, as well as maintenance and high costs. Environmental testing plays an important role in improving product reliability. In other words, without environmental testing, it is impossible to correctly identify product quality and ensure product quality. Environmental testing runs through the development, production, and use of products, usually involving design, improvement, and production testing. The more authentic and accurate the environmental test, the better the reliability of the product. It is applied to product research testing, type testing, inspection testing, acceptance testing, and safety testing.
6. To improve product reliability, develop and improve reliability testing plans, and provide a basis for users to choose products. Climate and environmental reliability test items: high temperature, low temperature, temperature shock (gas and liquid), immersion, temperature cycling, low pressure, high and low temperature, constant humidity, high pressure cooking, sand and dust, salt spray corrosion, rain exposure, solar radiation, photoaging, etc.
