ÖNORM EN 13732

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. 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. 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. Noise is not considered to be a significant hazard, but a relevant one for bulk milk coolers. This standard does not cover the calibration requirements for the tank to be used as a system for payment purpose. This standard is not applicable to bulk milk coolers on farms which are manufactured before the date of its publication as an EN.
