This Introduction is a guide for the use of all parts of IEC Publication 721-3. It contains background information including information on application and limitation of the classes given in various parts of IEC Publication 721-3. It describes the difference between the environmental conditions the product wil meet during its life, described by the classes in IEC Publications 721-3, and conditions of test used to assure that the product will work satisfactorily under such environmental conditions. The use of IEC Publication 721-3 in the design limitation of conditions and protection is also included. The differences are explained between extreme environmental conditions with a small probability of being exceeded, normally approached only for short periods, and more long-lasting normal environmental conditions.
