Scope

This section of IEC 60721-3 classifies groups of environmental parameters and their severities to which products are subjected when mounted for stationary use at weatherprotected locations under use conditions@ including periods of erection work@ down time@ maintenance and repair. Weatherprotected locations@ where products may be mounted for stationary use permanently or temporarily@ include land-based and offshore enclosed and sheltered locations. Use in and on vehicles is excepted. Environmental conditions directly related to explosion hazards@ fire extinction and ionizing radiation are excluded. Only environmental conditions as such are considered. No special description of the effects of these conditions on the products is given. Environmental conditions directly related to explosion hazards@ fire extinction and ionizing radiation are excluded. Any other unforeseen incidents are also excluded. The possibility of their occurrence should be taken into account in special cases. Microclimate within a product is not included. Conditions of stationary use at non-weatherprotected locations@ portable and non-stationary use@ use in vehicles and ships@ conditions of storage and transportation@ and microclimates inside products are given in other sections of IEC 60721-3. A limited number of classes of environmental conditions is given@ covering a broad field of application. The user of this standard should select the lowest classification necessary for covering the conditions of the intended use.
