    Abstract - (Show below) - (Hide below)

    Establishes groups of environmental parameters and their severities to which products together with their packaging are subjected when stored. Limited to those which may directly affect the products of their ultimate performance. Only environmental conditions as such are considered. No special description of the effects of these conditions on the products is given. Transfer during storage is not included. Environmental conditions directly related to fire or explosion and conditions related to ionizing radiation are excluded. Any unforeseen incidents are also excluded.
