1.1 This document specifies requirements for design, performance, safety and hygiene of refrigerated bulk milk coolers and the related methods of test.

NOTE The informative Annex J gives some elements regarding the estimation and calculation of energy consumption.

This document deals with all significant hazards, hazardous situations and events relevant to bulk milk coolers on farm, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

It applies to refrigerated bulk milk tanks with air-cooled condensing units and automatic control intended for installation on farms or at milk collection points. It applies to tanks for two milkings (24 h), four milkings (48 h) and six milkings (72 h), in which the cooling takes place totally (non-pre-cooled milk) or partially (in case of pre-cooled milk) within the tank. It also applies to tanks in combination with a continuous system of milking (e.g. milking with robot).

1.2 This document does not cover:

— mobile tanks;

— tanks intended to be tilted for drainage;

— equipment for delivering the milk to the tank;

— equipment for pre-cooling of the milk;

— the hazards due to the use of other energy than electrical energy;

— pressure aspect of vacuum tanks (i.e. tanks where the inner part of the vessel is designed to operate at a pressure below atmospheric pressure).

1.3 Noise is not considered to be a significant hazard, but relevant for bulk milk coolers. This document therefore includes information in 7.1 and in Annex A concerning the manufacturer's declaration of the noise emission level of the cooler.

1.4 This document does not cover the calibration requirements for the tank to be used as a system for payment purpose.

1.5 This document is not applicable to bulk milk coolers on farm which are manufactured before the date of its publication as EN.
