家用及类似用途电器.安全性.第2-89部分:带插入式或间接冷冻装置或压缩机的商用制冷设备的的特殊要求

[中文适用范围]： 第 1 部分的本条款由以下内容取代。本国际标准规定了电动商用制冷设备的安全要求，这些制冷设备具有内置压缩机或按照制造商的说明（分体系统）以两个单元组装为单个设备。注 101：本标准范围内的器具示例包括 C 冷藏展示柜和储藏柜； ?C冷藏推车柜； ?C服务柜台和自助服务柜台； ?C 急速冷冻机和急速冷冻机。在可行的情况下，本标准涉及这些类型的设备所带来的常见危险。它不涵盖 ISO 标准中涉及的制冷器具的构造和操作特征。注 102 请注意，对于用于车辆、船舶或飞机的器具，可能需要附加要求； ?C 在许多国家@国家当局规定了附加要求。注103 本标准不适用于 ?C 家用制冷器具(IEC 60335-2-24) ?C 工业制冷系统； ?C 电机压缩机 (IEC 60335-2-34)； ?C 商业分配器具和自动售货机（IEC 60335-2-75）； ?C 商用冰淇淋器具； ?C 商用制冰机； ?C冷温室； ?C 多个冷藏室，配有远程压缩机。注 104：本标准不包括在每个单独的制冷剂回路中充注超过 150 g 易燃制冷剂的器具。对于每个制冷剂回路中可燃制冷剂充注量超过 150 克的设备以及安装，可采用 ISO 5149。因此，不能使用本第 2 部分评估此类设备的安全性。 [外文原描述]： IEC 60335-2-89:2010 specifies safety requirements for electrically operated commercial refrigerating appliances that have an incorporated compressor or that are supplied in two units for assembly as a single appliance in accordance with the manufacturer's instructions (split system). Appliances that are within the scope of this standard are: - refrigerated display and storage cabinets; - refrigerated trolley cabinets; - service counters and self-service counters; - blast chillers and blast freezers. The principal changes in the edition with respect to the first edition are as follows: - aligns the text with IEC 60335-1 and its Amendments 1 and 2; - introduces requirements for appliances using transcritical refrigerant systems; - introduces an enhanced flexing test. The attention of National Committees is drawn to the fact that equipment manufacturers and testing organizations may need a transitional period following publication of a new, amended or revised IEC publication in which to make products in accordance with the new requirements and to equip themselfs for conducting new or revised tests. It is the recommendation of the committee that the content of this publication be adopted for implementation nationally not earlier than 12 months or later than 36 months from the date of publication. The contents of the interpretation sheet of July 2014 have been included in this copy. This publication is to be read in conjunction with IEC 60335-1:2010 .
