IEC 60335-2-104:2021 RLV包含官方IEC国际标准及其红线版本。Redline版本仅提供英文版本，为您提供了一种快速简单的方法来比较IEC官方标准与其以前版本之间的所有变化。 IEC 60335-2-104:2021涉及从空调和制冷设备中回收和/或再循环制冷剂的电气回收和/或再循环设备的安全性。这适用于空调、热泵和制冷设备，包括开式驱动或电机压缩机，其最大额定电压对于单相电器不超过300 V，对于所有其他设备不超过600 V。 不打算用于正常家庭使用但可能对公众造成危险的电器，如打算供商店、轻工业和农场的服务人员使用的电器，属于本标准的范围。上面提到的器具可以由一个或多个工厂制造的组件组成。如果在多于一个组件中提供，则单独的组件将一起使用，并且要求基于匹配组件的使用。 这第二版取消并取代了2003年出版的第一版。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: a)第1条-对范围进行了编辑，以反映本文件中的“设备”是指从空调和制冷设备中回收和/或再循环制冷剂的回收和/或再循环设备。 b)第2条-增加了规范性参考文献。 c)第3条-删除了一些定义，增加了一些定义。 (d)第7款。1-一些标记被删除，一些被添加。 e)子条款7.6-增加了“阅读操作手册”的符号，“操作手册；操作说明”包括着色放置在可见位置；X MPa后的最大允许压力标记。 f)修改了第19.11.4款。 g)修改了第21.1款。 h)修改了第21.2款。 i)修改子条款22.102。 j)修改了子条款22.104.1.1。 k)修改了子条款22.104.5。 l）修改了子条款22.104.10。 m)修改子条款22.104.11。 n)修改子条款22.105.1。 o)修改子条款22.107。 p)将第30.2款移至第29款。 q）删除附件AA，代之以附件AA。 r)在添加到附件BB后，删除了附件BB，并替换为以前的IEC 60335-2-104附件CC（规范性）兼容性要求。s)删除附件DD，代之以附件CC。 t)增加了新的附件DD。 u)增加了新的附件EE。 本第2部分应与IEC 60335-1:20 10第五版及其修正案一起使用。

IEC 60335-2-104:2021 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 60335-2-104:2021 deals with the safety of electrical recovery and/or recycle equipment to recover and/or recycle refrigerant from air conditioning and refrigeration equipment. This applies to air-conditioning, heat-pumps and refrigeration equipment incorporating open drive or motor-compressors, their maximum rated voltages being not more than 300 V for single phase appliances and 600 V for all other equipment.
Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as appliances intended to be used by service personnel in shops, in light industry and on farms, are within the scope of this standard.
The appliances referenced above may consist of one or more factory made assemblies. If provided in more than one assembly, the separate assemblies are to be used together, and the requirements are based on the use of matched assemblies.
This second edition cancels and replaces the first edition published in 2003. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) Clause 1 - The scope has been edited to reflect that "appliance" in this document means recovery and/or recycle equipment to recover and/or recycle refrigerant from air-conditioning and refrigeration equipment.
b) Clause 2 - Normative references were added.
c) Clause 3 - Some definitions were deleted, some were added.
d) Subclause 7.1 - Some markings were deleted, some were added.
e) Subclause 7.6 - Symbols were added for “read operator’s manual”, “operator’s manual; operating instructions” including coloring are placed in visible location; maximum allowable pressure markings following X MPa.
f) Subclause 19.11.4 was modified.
g) Subclause 21.1 was modified.
h) Subclause 21.2 was modified.
i) Subclause 22.102 was modified.
j) Subclause 22.104.1.1 was modified.

p) Subclause 30.2 was moved to Clause 29.
q) Annex AA was deleted and replaced with Annex AA.
r) Annex BB was deleted and replaced with former IEC 60335-2-104 Annex CC (normative) Compatibility requirements following addition to Annex BB.
s) Annex DD was deleted and replaced with Annex CC.
t) New Annex DD was added.
u) New Annex EE was added.
This part 2 is to be used in conjunction with the fifth edition of IEC 60335-1:2010 and its amendments.
