3.12 Operation Mast-Mounted Equipment -40 C – +55 C
In addition to the “Basic class” this class is aimed for even more exposed
situation such as: areas with expected higher temperature, ice falling from
structures above, mast and poles structure which will expose the equipment to
higher vibration probability, drifting snow and hail.
3.12.1 Climatic Conditions
This environmental class corresponds in full to “Operation Mast-mounted
Equipment -33 - +45 C” with the exception for requirement stated below.
