Classification of environmental conditions. Environmental conditions appearing in nature - Earthquake vibration and shock Ingestion-build-65808 cooling towers1 Scope and object This part of IEC 721 deals with environmental conditions appearing in nature, and in particular related to earthquake vibration and shock. Its object is to define some fundamental properties and quantities for characterization of earthquakes as background material for the severities to which products are liable to be exposed during storage and use. Accelerations given are for ground surface conditions only. Conditions related to
