Classification of environmental conditions. Classification of groups of environmental parameters and their severities - Microclimates inside products1 Scope This section of IEC 7213 defines classes of microclimatic conditions, to which components (basic parts, assemblies, built in units) may be subjected inside products, which are used under the climatic conditions as classified in sections IEC 72133 and IEC 72134. Characteristic parameters for the microclimates are high air temperature and high relative air humidity. Further parameters of the climatic classes e. g. low temperature may affect the
