In order to ensure the stability of product performance in high temperature and high humidity and other harsh environments, Sanwood Technology has introduced a Walk-in Environmental Test Chamber that strictly follows the IEC68-2-30 Test Db (Alternating Humidity and Heat Test Methods) standard to provide companies in the fields of industrial manufacturing, electrical and electronic appliances, automotive parts and components, aerospace and other fields with accurate and efficient testing solutions to help improve product quality.
Standard interpretation
IEC68-2-30 is an environmental test standard formulated by the International Electrotechnical Commission (IEC), in which Test Db (alternating humidity and heat test) is mainly used to assess the ability of products to withstand temperature cycling and high humidity environments. The test by simulating high temperature and high humidity → low temperature and high humidity → return to normal cyclic changes in product quality, performance of each temperature, humidity section of the endurance test, such as: insulation of electronic components, corrosion of metal materials, product sealing and structural stability.
The test is widely used in electronic equipment, automotive parts, military products, photovoltaic components and other industries, to ensure the long-term reliability of products in the tropics, coastal and other high humidity environment.
