环境条件分类 环境参数组分类及其严酷程度分级 第4部分：无气候防护场所固定使用
Application Summary AI generated
This standard defines environmental parameters and severity levels for equipment used in stationary, non-weatherprotected locations, such as outdoor industrial sites, substations, or rooftop installations. It is applied by engineers to specify testing conditions for temperature, humidity, solar radiation, and wind exposure, ensuring product reliability in open-air environments without shelter. The standard is primarily used in product design and qualification testing for electrical, electronic, and mechanical systems exposed to natural climatic conditions.
