Reliability Performance Testing

Early in the development phase of a product,design flaws areidentified and improved mainly through experimentation, and then new problems are identified through further testing. Experience shows that about 70% of the design defects can only be found by testing the prototype. The test is not only a powerful measure to improve the design of the product development and production process, but also an essential means to evaluate whether the product characteristics meet the requirements.

Products are subjected to various environmental factors (including natural environment and induced environment) in the whole life process of manufacturing, storage and transportation, and deployment and use, especially the environmental conditions in the use phase are usually harsh, through long-term practice, people realize that environment and product reliability are closely related and play a key role and influence, and environmental technology is the basis of product reliability test, and proper and Effective use of environmental technology is conducive to improving the reliability of products.

Environmental test is a test to assess the adaptability of the product to the expected working environment ; Reliability test is designed and improved according to the reliability Requirements, with reliability objectives and tests under typical environmental conditions.

Q&A

Question 1 : Which aspect of reliability testing can mainly solve the problem?

Answer 1 : Reliability testing has the following key roles : (1) to expose the defects in various aspects of the trial product in the development stage and evaluate the reliability of the product to achieve the predetermined index ; (2) to provide information for monitoring the production process in the production stage ; (3) to identify or accept the reliability of the final product ;

(4) to expose and analyze the failure law of the product under different environmental and stress conditions and the related (4) expose and analyze the failure mode and failure mechanism of the product under different environmental and stress conditions ; (5) develop and improve the reliability test program to improve the reliability of the product and provide the basis for the

user to select the product.

Question 2 : What is the salt spray test? Salt spray test 48 hours is the product needs to be tested for 48 hours?

Answer 2 : Salt spray test is a kind of environmental test mainly using salt spray test equipment created by the artificial simulation of salt spray environmental conditions to assess the

corrosion resistance of products or metal materials. Salt spray test 48 hours is not necessarilyrequired 48 hours, the use of work to accelerate the simulation of salt spray environmental test, in its volume space with artificial methods, resulting in salt spray environment to assess the quality of salt spray corrosion resistance of products, salt spray test on products, the time to produce results is also greatly reduced.

Question 3 : What is the IP rating standard?

Answer 3 : IP is the abbreviation of Ingress Protection, IP rating is for the protection level of electrical equipment casing against foreign body intrusion, the source is the International Electrotechnical Commission standard IEC 60529 ; IP rating format is IPXX, where XX is two Arabic numbers, the first number indicates dustproof ; the second number by indicating waterproof, the larger the number means its protection The larger the number, the better the protection.

Question 4 : How long does it take to issue a report for aging experiments?

Answer 4 : The aging test needs to consider the aging time of the sample itself, as well as the standard method on the care time of the specimen after aging. Combine this with the time needed to test other items before and after aging to calculate. In the case that the laboratory does not need to schedule, the time can be in accordance with the aging time plus 10 working days as the time of report issuance.
