CEN/TC 153/WG 8 - Bulk milk coolers

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 K 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 installed, used and maintained as intended by the manufacturer (see informative Annex A).
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 (tank of which the inner vessel is designed to operate at a pressure below atmospheric pressure);
-   calibration requirements for the measurement of the milk volume.
1.3   This document is not applicable to bulk milk coolers on farms which are manufactured before the date of its publication as EN.

1.1   This European Standard specifies requirements for design, performance, safety and hygiene of refrigerated bulk milk coolers and the related methods of test.
This standard deals with all significant hazards, hazardous situations and events relevant to bulk milk coolers on farms, 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 collecting 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.
Performance requirements in 5.5.1.2.1 and 5.5.1.2.2 do not apply to tanks in combination with instant cooling or in association with a continuous system of milking (e.g. milking with robot).
1.2   This European Standard does not cover:
-   mobile tanks;
-   tanks intended to be tilted for drainage;
-   equipment for delivering the milk to the tank;
-   equipment for pre-cooling or instant cooling of the milk;
-   the hazards due to the use of other energy than electrical energy;
-   pression aspect of vacuum tanks.
1.3   Noise is not considered to be a significant hazard, but a relevant one for bulk milk coolers. This standard 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 standard does not cover the calibration requirements for the tank to be used as a system for payment purpose.
1.5   This standard is not applicable to bulk milk coolers on farms which are manufactured before the date of its publication as an EN.

1.1   This European Standard specifies requirements for design, construction, performance, suitability for use, safety and hygiene of refrigerated bulk bovine milk coolers and the related methods of test.
It applies to refrigerated bulk milk tanks with air cooled condensing units and automatic control intended for installation on farms or at milk collecting 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 or partially within the tank.
Performance requirements in 5.4.1.2.1 and 5.4.1.2.2 do not apply to tanks where cooling does not take place totally within the tank nor where the tank is associated with a continuous system of milking (e.g. milking with robot).
1.2   This European Standard does not cover:
-   mobile tanks;
-   tanks intended to be tilted for drainage;
-   equipment for delivering the milk to the tank;
-   equipment for pre-cooling or instant cooling of the milk.
1.3   This standard covers significant hazards at machines falling within this scope when used as intended by the manufacturer and as identified by risk assessment (see EN 1050:1997).
Noise is not considered to be a significant hazard for bulk milk coolers. This standard 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 standard does not cover the calibration requirements for the tank to be used as a system for payment purpose.
1.5   This standard applies primarily to the machines which are manufactured after its date of issue.
