家用和类似用途电器的安全第2-58部分:商用电动洗碗机的特殊要求

[中文适用范围]： 本国际标准涉及电动洗碗机的安全性，用于清洗盘子、餐具、玻璃器皿、刀具和类似物品，带有或不带有水加热或干燥装置，不适用于家用，其额定电压不超过单相电器在一相和中性线之间连接时为250V，其他电器为480V。 [外文原描述]： IEC 60335-2-58:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60335-2-58:2017 deals with the safety of electrically operated dishwashing machines for washing plates, dishes, glassware, cutlery and similar articles, with or without means for water heating or drying, not intended for household use, their rated voltage being not more than 250 V for single-phase appliances connected between one phase and neutral and 480 V for other appliances. These appliances are used for example in restaurants, canteens, hospitals, and commercial enterprises such as bakeries, butcheries, etc. Examples of such appliances are conveyor dishwashers; batch dishwashers and brush machines. Requirements to avoid backsiphonage of non-potable water into the water mains are specified in Annex BB. The electrical part of appliances making use of other forms of energy is also within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by these types of appliances. Attention is drawn to the fact that for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary. This standard does not apply to the following: appliances designed exclusively for industrial purposes, for example machines used in the food industry for cleaning receptacles that serve as packaging for final products (e.g. bottle-cleaning machines), and machines used in manufacturing processes; sterilizers and washer-disinfectors used to treat medical materials (IEC 61010-2-040); dishwashers that do not form one functional unit, for example where a transportation device transfers the load from one separate unit to another; separately driven transport devices not confined in the appliance; appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas). This fourth edition cancels and replaces the third edition published in 2002 including its Amendment 1 (2008) and its Amendment 2 (2015). This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: The text has been aligned with Edition 5.2 of Part 1; Requirements and tests for vertical-lift doors with and without a counterbalance system are clarified (20.103, 20.104); Some notes have been converted to normative text or deleted (7.15, 9, 10.1, 11.7, 15.3, 19.4, 20.1, 20.102, 22.106, 22.107, 23.3). This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the fifth edition (2010) of that standard 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 themselves 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 its publication.
