GB/T 19608.2-2022 "Classification of Special Environmental Conditions - Part 2: Dry and Hot Desert" was released in July 2022 and implemented in February 2023, replacing the 2004 edition. This standard addresses the unique environmental conditions of dry and hot deserts, specifying relevant environmental parameters and classification of severity levels. It is applicable to products stored, transported, handled, and used in such environments. The standard covers various conditions, including climate, chemically active substances, mechanically active substances, and wind-sand landforms. It introduces new parameters such as annual maximum relative humidity, chlorine, and hydrogen fluoride, and refines classification standards for environments like wind-sand and vibration. It provides technical support for equipment development, protective design, and quality testing in desert regions and is also applicable to related products in certain dry and hot desert areas of Central Asia.
