IEC 60335-2-34:2021作为IEC 60335-2-34:2021 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 60335-2-34:2021涉及密封（密封和半密封型）电动压缩机及其保护和控制系统（如有）的安全性，这些压缩机旨在用于家用和类似用途的设备，并符合适用于此类设备的标准。它适用于在正常使用中可能出现的最恶劣条件下单独测试的电机压缩机，其额定电压对于单相电机压缩机不超过250 V，对于其他电机压缩机不超过600 V。 本标准还涵盖: -多速电机-压缩机，即电机-压缩机，其速度可以设置为不同的值； -可变容量电动压缩机，其是其中压缩机的容量以固定速度控制的电动压缩机。 包含电机压缩机的设备的示例有: -滚筒干燥机(IEC 60335-2-11)； -制冷设备、冰淇淋设备和制冰机（IEC 60335-2-24）； -电热泵、空调和除湿机（IEC 60335-2-40）； -商业分配器具和自动售货机(IEC 60335-2-75)； -带有内置或远程制冷剂单元或压缩机的商用制冷器具和制冰机(IEC 60335-2-89)； -测量、控制和实验室用电气设备（IEC 61010-2-011）； -专业冰淇淋制造商(IEC 60335-2-118)； -制冷系统和热泵-设计、建造、测试、标记和文件（ISO 5149-2). 本标准不取代与使用电动压缩机的特定设备相关的标准要求。然而，如果所使用的电机-压缩机类型符合本标准，则特定设备标准中规定的电机-压缩机的测试可能不需要在特定设备或组件中进行。如果电机-压缩机控制系统与特定电器控制系统相关联，则可能需要对最终电器进行额外测试。 就实际而言，本标准涉及家用电器中使用的电机压缩机带来的常见危害，这些危害是家中和周围所有人都会遇到的。然而，它通常没有考虑到: -幼儿或体弱者在无人看管的情况下使用器具；-幼儿玩电器。 提请注意以下事实: -对于拟用于车辆或船上电器的电动压缩机，是否有其他要求？ments可能是必要的； -在许多国家，国家卫生当局、负责保护劳工的国家当局和类似当局规定了额外的要求。 本标准不适用于: -专为工业用途设计的电机压缩机； -用于打算在特殊条件占优势的地方使用的电器的电机压缩机，例如存在腐蚀性或爆炸性气氛（灰尘、蒸汽或气体）。 如果在具有跨临界制冷系统的设备中使用的制冷剂R-744的电机压缩机配备了泄压装置，则在对最终设备进行测试期间检查是否符合这些装置的要求。本第六版取消并取代2012年发布的第五版、修正案1:20 15和修正案2:20 16。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: -它使文本与IEC 60335-1，第5.2版一致； -扩大了应用类别和测试（3.1.102，附件AA）； -引入使用电动机进行绕组相容性测试（3.8.102，附录BB）； -三角形的高度，已引入符号ISO 7010 W021(7.14)； -一些注释被转换为规范性文本（1、15.3、22.21、23.8、29.3.4，图AA.1）； -第6.101条中的注释在第11条中变为规范； -引入了可选的耐压试验（18.101，附录EE）； -澄清外壳内部绝缘的兼容性测试（22.9); -澄清适用于海拔超过2 000米（29.1）的电机压缩机外壳内的间隙； -更新了规范性参考文献和相关文本（24.101，附件DD）； -温度加热循环后系绳的断裂强度已更新（附录CC）。 本第2部分应与最新版本的IEC 60335-1及其修正案一起使用。它是在该标准第五版（2010年）的基础上建立的。

IEC 60335-2-34:2021 is available as IEC 60335-2-34:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 60335-2-34:2021 deals with the safety of sealed (hermetic and semi-hermetic type) motor-compressors, their protection and control systems, if any, which are intended for use in equipment for household and similar purposes and which conform with the standards applicable to such equipment. It applies to motor-compressors tested separately, under the most severe conditions that may be expected to occur in normal use, their rated voltage being not more than 250 V for single-phase motor-compressors and 600 V for other motor-compressors.
This standard also covers:
- multi-speed motor-compressors, that are motor-compressors, the speed of which can be set to different values;
- variable capacity motor-compressors that are motor-compressors where the capacity of the compressor is controlled at fixed speeds.
Examples of equipment which contain motor-compressors are:
- tumble dryers (IEC 60335-2-11);
- refrigerating appliances, ice-cream appliances and ice-makers (IEC 60335-2-24);
- electrical heat pumps, air-conditioners and dehumidifiers (IEC 60335-2-40);
- commercial dispensing appliances and vending machines (IEC 60335-2-75);
- commercial refrigerating appliances and ice-makers with an incorporated or remote refrigerant unit or compressor (IEC 60335-2-89);
- electrical equipment for measurement, control, and laboratory use (IEC 61010-2-011);
- professional ice-cream makers (IEC 60335-2-118);
- refrigerating systems and heat pumps – Design, construction, testing, marking and documentation (ISO 5149-2).
This standard does not supersede the requirements of standards relevant to the particular appliance in which the motor-compressor is used. However, if the motor-compressor type used complies with this standard, the tests for the motor-compressor specified in the particular appliance standard may not need to be made in the particular appliance or assembly. If the motor-compressor control system is associated with the particular appliance control system, additional tests could be necessary on the final appliance.
So far as is practical, this standard deals with the common hazards presented by motor-compressors used in appliances which are encountered by all persons in and around the home. However, it does not in general take into account:
- the use of appliances by young children or infirm persons without supervision;
- playing with the appliances by young children.
Attention is drawn to the fact that:
- for motor-compressors intended to be used in appliances in vehicles or on board ships, additional require？ments could be necessary;
- in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.
This standard does not apply to:
- motor-compressors designed exclusively for industrial purposes;
- motor-compressors used in 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).
If motor-compressors for refrigerant R-744 used in appliances with a transcritical refrigeration system are equipped with pressure relief devices, compliance with the requirements for these devices is checked during the tests on the final appliance.
This sixth edition cancels and replaces the fifth edition published in 2012, Amendment 1:2015 and Amendment 2:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
- it aligns the text with IEC 60335-1, Ed 5.2;
- application categories and tests have been extended (3.1.102, Annex AA);
- use of a motorette for winding wire compatibility tests introduced (3.8.102, Annex BB);
- height of the triangle, symbol ISO 7010 W021 has been introduced (7.14);
- some notes are converted to normative text (1, 15.3, 22.21, 23.8, 29.3.4, Figure AA.1);
- note in Subclause 6.101 becomes normative in Clause 11;
- optional pressure endurance test introduced (18.101, Annex EE);
- compatibility test for insulation inside the housing clarified (22.9);
- clarification of clearances inside the housing for motor-compressors suitable for use at altitudes exceeding 2 000 m (29.1);
- normative references and associated text have been updated (24.101, Annex DD);
- breaking strength of tie cord after temperature heating cycle has been updated (Annex CC).
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.
