GB/T 4857.2-2005 is part of the basic test standard for transported Encasement parts, focusing on temperature and Humidity adjustment treatment. The standard clarifies the importance of temperature and Humidity adjustment for the performance test of transported Encasement parts, specifies a variety of standard temperature and Humidity conditions and corresponding applicable scenarios. Describe the adjustment process in detail, including the placement of Encasement parts, processing time, etc. Through standardized temperature and Humidity adjustment, simulate the temperature and Humidity conditions of the product in different transportation environments, and provide a unified and practical pretreatment for subsequent Encasement performance tests, making the test results more Reliability and helping to improve the protection effect of Encasement in complex environments.
