705.20 Terms and definitions
For the purposes of this document, the following terms and definitions apply:
705.20.1
agricultural and horticultural premises
rooms, locations or areas where
– livestock are kept;
– feed, fertilizers, vegetable and animal products are produced, stored, prepared or processed;
– plants are grown, such as greenhouses.
NOTE In agricultural and horticultural premises special requirements for the selection and erection of electrical equipment
apply due to special external influences, e.g. influence of moisture, dust, aggressive chemical vapours, acids or salts on
electrical equipment. In addition an increased fire risk may exist due to the presence of highly flammable substances.
Agricultural and horticultural premises include, for example:
– housing for animals such as cattle, pigs, horses, sheep, goats and chicken-houses including adjacent rooms (e.g. feed
processing locations, milking-machine locations, milk-storage rooms);
– barns, stores and storerooms for hay, straw, feed, fertilizers, grain, potatoes, beets, veg
...
