Scope

This part of GB/T 4798 specifies the various microscopic conditions that may be encountered by internal components (basic parts, components and built-in equipment) when the product is used under the climatic conditions of IEC 60721-3-3 or IEC 60721-3-4. Class of weather conditions. The characteristic parameters of the microclimate are high air temperature and high relative air humidity. Some other climate level parameters such as low temperature may also have additional effects on components, but are not considered in this section. Considering the representative extreme high temperature, a limited number of microclimate grades are stipulated. Users of this standard should select the lowest grade that meets the intended use.
