IEC 60721-2-9:2014 is intended to be used to define the strategy for arriving at an environmental description from measured data when related to a product’s life cycle. Its object is to define fundamental properties and quantities for characterization of storage, transportation and in-use shock and vibration data as background material for the severities to which products are liable to be exposed during those phases of their lifecycle.<\/p>\n
