Classifies groups of environmental parameters and their severities to which products are subjected during portable and non-stationary use. These include: the environmental conditions at locations where the product may be placed or used temporarily, the change of environmental parameters due to change of location and conditions related to transfer of the product between different locations. The environmental conditions classified do not take into account the use profile of the product. Limited to those which may directly affect the performance of products. Environmental conditions directly related to fire or explosion hazards and conditions related to ionizing radiation are excluded. Microclimate within a product is not included.
