Classification of environmental conditions. Guidance for the correlation and transformation of environmental condition classes of IEC 60721-3 to the environmental tests of IEC 60068 - Stationary use at weatherprotected locations Ingestion-build-224916 ISO 9974 and ISO 11926

ISO 9974 and ISO 11926 are not to be used for new designs in hydraulic fluid power applications

1st (excluding coal-based) and 2nd family gases up to a working pressure of 7 bar (gauge) and a working temperature of up to 150 °C

to be installed vertically (within 15°) into the external face of buildings

This has the benefit of giving the organization a better understanding of the types of energy they use and consume

The glass transition temperature is defined to be 100 °C minimum

Classification of environmental conditions. Guidance for the correlation and transformation of environmental condition classes of IEC 60721-3 to the environmental tests of IEC 60068 - Stationary use at weatherprotected locations Ingestion-build-224916 ISO 9974 and ISO 119261 Scope and object This part of IEC 60721 is a technical report dealing with the correlation and transformation of the conditions given in IEC 6072133 to the environmental tests defined in IEC 600682. An environment may consist of a number of environmental conditions such as dynamic, climatic and biological, and other effects due to chemically and mechanically active sub stances. In this report, only dynamic and climatic conditions have been
