GB/T 20969.1-2007
AbolishedSpecial environmental condition - Machinery for plateau - Part 1: Requirements for internal combustion engines on plateau
特殊环境条件 高原机械 第1部分：高原对内燃动力机械的要求
Application Summary AI generated
This standard specifies technical requirements for internal combustion engines used in machinery operating at high altitudes (above 1,000 meters), addressing power derating, starting performance, and cooling system adjustments due to low air density and oxygen levels. It is applied in the design, manufacturing, and testing of construction, mining, and material handling equipment intended for plateau regions, such as the Qinghai-Tibet Plateau. The standard ensures reliable engine operation and compliance with safety and performance criteria under hypoxic and low-pressure conditions.
