Introduction
The requirements of this part of HD 60364 supplement, modify or replace certain of the general
requirements contained in Parts 1 to 6 of HD 60364.
The clause numbering appearing after 705 refers to the corresponding parts or clauses of HD 60364,
Parts 1 to 6. Numbering of clauses does not, therefore, necessarily follow sequentially. Numbering of
figures and tables takes the number of this part followed by a sequential number.
The absence of reference to a part or a clause means that the general requirements contained in
Parts 1 to 6 of HD 60364 are applicable.
For products used in agricultural and horticultural premises presenting risk of hazardous atmospheres
due to combustible gas and/or dust, the EN 60079 series and the EN 61241 series apply.

The requirements of this part of HD 60364 apply to fixed electrical installations inside and outdoors of
agricultural and horticultural premises. Some of the requirements are also applicable to other locations
that are in common buildings belonging to the agricultural and horticultural premises.
Rooms, locations and areas for household applications and similar are not covered by this standard.
If some of the special requirements of Part 7-705 are also applicable for residences and other locations
in such common buildings this is stated in the normative text.

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
