Classification of environmental conditions - Part 3: Classification of groups of environmental parameters and their severities - Section 9: Microclimates inside products (IEC 721-3-9:1993, AMD. 1:1994 and CORR. 1:1994, IDT)
This Malaysian Standard defines the classes of microclimate conditions, to which components (basic parts, assemblies, built-in units) may be subjected inside the products, which are used under the climate conditions as classified in IEC 60721 Part 3 Sections 3 and 4. The characteristic parameters for microclimates are high air temperature and high relative air humidity. Further parameters of the climate classes e.g. low temperature may affect the components additionally.
