GB/T 14092.2-2023 "Environmental Conditions for Machinery Products – Part 2: Cold" specifies the environmental parameters and severity grades for machinery products in cold environments, applicable to various types of machinery used in cold regions. It clearly defines and refines temperature ranges, including an extreme cold range of -50°C to -30°C, and distinguishes temperature requirements for different scenarios such as indoor and outdoor use, transportation, and storage. Additionally, it categorizes humidity into low, medium, and high levels, along with corresponding atmospheric pressure conditions. The standard sets requirements for product performance in low-temperature startup, operational stability, and sealing protection. It recommends the use of cold-resistant materials and optimizes structural and lubrication system designs, providing guidance for the design and manufacturing of products intended for use in cold environments.
