Locations with significant vibration and shock, such as those transmitted from machines or passing vehicles in the vicinity. 1K4 Locations which may have openings directly to the open air, that is they may be only partially weatherprotected. Heating may be used to raise low temperatures, especially where there is a large difference between the conditions of this class and the open- air climate. Stored products may be sub-jected to condensed water, to water from sources other than rain, and to formation of ice .Stored products may be subjected to limited wind-driven precipitation. With and without additional protective coating “W” 2K3 Transportation in unventilated enclosures and in non-weatherprotected conditions with restrictions to the “general open-air climates”, excluding “cold” and “cold tem- perature climates”. Transportation by air only in heated, pressurized holds is included. The product may be moved between cold outdoor and warm indoor conditions. It may be exposed to direct solar radiation, precipitation and splashing water. Transportation in all kinds of lorries and trailers in areas with well-developed road systems. It also includes transportation in aircraft, by ships and by trains with specially designed shock reducing buffers. With and without additional protective coating “W” 1M3 3M7 Locations where the level of vibration is very high, e.g. for products mounted directly on machines. 3K5 may be sub-jected to formation of ice Classification of climatic and mechanical environmental conditions additional protective coating for 420/460/490 series Enclosed locations having neither tempe- rature nor humidity control. Heating may be used to raise low temperatures where there is a large difference between the conditions of this class and the open-air climate. Installed products .The conditions of this class may be found in some entrances and industrial staircases of buil- dings, in garages, cellars, certain work- shops, buildings in factories and industrial process plants, ordinary storage rooms for frost-resistant products, farm buildings, etc. With additional protective coating “W” 2M2 Description of classification acc. to IEC 60721-3-x and examples of application Stationary use acc. to IEC 60721-3-3 Transportation acc. to IEC-60721-3-2 Storage acc. to IEC 60721-3-13M4 Locations with significant vibration and shock, e.g. transmitted from machines or passing vehicles in the vicinity. 3K5 not be sub-jected to formation of ice Enclosed locations having neither tempe-rature nor humidity control. Heating may be used to raise low temperatures, especially where there is a large difference between the conditions of this class and the open-air climate.
