Foreword
With the rapid development of modern industrial technology, the application fields of electrical and electronic products are becoming increasingly broad, and the environmental conditions they are subjected to are becoming more and more severe. Complex and diverse. Only by reasonably stipulating the environmental conditions of the product and correctly selecting the environmental protection measures for the product can we ensure that the product is protected from damage during storage and transportation and is safe and reliable during use. Therefore, artificial simulated environment testing of electrical and electronic products is an indispensable and important link to ensure their high quality. Artificial simulated environment tests are scientific summaries of actual environmental impacts and are typical, standardized, easy to use, and easy to compare. The diversification of environmental conditions and the importance of environmental testing also put forward more stringent requirements for environmental testing equipment.
Thermal aging test chamber is suitable for adaptability testing of electrical, electronic, instrumentation and other products, parts and materials when stored, transported and used in high temperature environments. It is suitable for all types of electronics, electricians, electrical appliances, plastics, etc. Reliability testing equipment for heat resistance testing and quality control engineering of raw materials and devices. This equipment is especially suitable for high temperature resistance testing of plastics, optical fibers, and other products.
Reference standards
Meet the requirements of test standards such as B/"Air Thermal Aging Test Chamber" and B/3-"Hot Air Accelerated Aging and Heat Resistance Test of Vulcanized Rubber or Thermoplastic Rubber".
