The aging test mainly refers to the thermal oxygen aging test for rubber, plastic products, electrical insulation materials and other materials; or the ventilation aging test for electronic parts and plastic products. The aging test is divided into temperature aging, sunlight aging, loading aging and so on.
High-temperature aging is generally carried out in several grades. In industry, it is generally used at 70 degrees, 4 hours, and 15 degrees. Generally there are 40 degrees, 55 degrees, 70 degrees, and 85 degrees. The time is generally 4 hours. According to the number of aging test products, it is divided into two methods to test
1. Aging box; mainly for plastic products, and products with a small quantity and volume are more practical
2. Aging cabinet or aging room; mainly for high-performance electronic products (such as: computer complete machines, monitors, terminals, automotive electronic products, power supplies, motherboards, monitors, switching chargers, etc.) A high-temperature, harsh-environment test equipment is an important experimental equipment to improve product stability and reliability, and an important production process for various manufacturers to improve product quality and competitiveness. This equipment is widely used in power electronics, computers , Communications, biological domination
The main aging test items are:
1. Thermal aging
Main reference standards: GB/T 7141, ASTM D3045, JIS K 6257, etc. The heat aging box has a program function, which can set the temperature change through the program, which is suitable for the needs of heat aging of various products.
Main application scope: heat aging test of various products, such as PCB boards, insulating rubber in electrical appliances, products with long-life requirements (such as the jacket material for cable-stayed bridges, the service life should be more than 20 years), etc. The progress of the product, the change of product performance, and the reliability of product use.
2. Humidity and heat aging
Main reference standards: general standards include GB/T 15905, GB/T 2573, etc. In addition, the change curve of humidity and temperature can be set according to different product standards and corporate standards, which is suitable for various complicated damp and heat aging tests. During the use of the product, it is susceptible to the dual effects of temperature and humidity. For some water-sensitive materials, such as PET, PBT, etc., a damp heat aging test is required to assess whether it is suitable for long-term use in a humid environment.
3. High and low temperature cycle
Main reference standards: GB/T 2423, JG/T 25 Architectural Coatings Freeze-Thaw Cycle Resistance Test Method and other standards, can be tested in accordance with the relevant test methods of high and low temperature cycles and freeze-thaw cycles in different product standards. Mainly used for testing of architectural coatings and equipment used in special environments.
