1.1本欧洲标准规定了冷藏散装牛奶冷却器的设计，性能，安全和卫生要求以及相关的测试方法。 本标准涉及到农场散装牛奶冷却器的所有重大危害，危险情况和事件，按照预期使用和在制造商合理预见的误用条件下（见第4条）。 适用于具有空冷冷凝机组的冷藏散装奶罐和用于安装在农场或牛奶收集点的自动控制。它适用于两个挤奶（24小时），四个挤奶（48小时）和六个挤奶（72小时）的罐，其中完全冷却（非预冷奶）或部分冷却（在预冷的情况下牛奶）在罐内。 5.5.1.2.1和5.5.1.2.2中的性能要求不适用于与即时冷却或连续挤奶系统（例如与机器人挤奶）相结合的罐体。 1.2本欧洲标准不包括: - 移动坦克 - 倾倒排水的坦克; - 将奶送到罐中的设备; - 预冷或即时冷却牛奶的设备; - 使用其他能源而不是电能的危害; - 真空罐的压力方面

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.
