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.
