IEC 60335-2-71:2018涉及用于家畜饲养和繁殖的各种电加热设备的安全性，例如:散热设备、电坐母鸡、孵化器、养鸡装置和动物加热板，设备的额定电压对于单相设备不超过250 V，对于其他设备不超过480 V。 本标准适用于家畜饲养和养殖用的包括电动机的加热器具。 本标准不适用于: -专为工业用途而设计的器具； -拟在有特殊条件的地方使用的器具，例如存在腐蚀性或爆炸性气氛（灰尘、蒸汽或气体）； -嵌入地板中的加热单元； -用于房间加热的柔性片状加热元件（IEC 60335-2-96); -房间加热器（IEC 60335-2-30）。 这第三版取消并取代了2002年出版的第二版及其修正案1（2007年）和修正案2（2012年）。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: -删除两段（导言）； -更新了规范性参考文献（第2条）； -符号(7.6)所需的颜色； -一些注释转换为规范性文本（19.2、21.101、22.104）。

IEC 60335-2-71:2018 deals with the safety of all kinds of electrical heating appliances used for livestock rearing and breeding, such as: heat-radiating appliances, electrical sitting-hens, incubators, chicken breeding units and heating plates for animals, the rated voltage of the appliances being not more than 250 V for single-phase appliances and 480 V for other appliances.
This standard applies to heating appliances used for livestock rearing and breeding that include an electrical motor.
This standard does not apply to:
- appliances designed exclusively for industrial purposes;
- 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);
- heating units embedded in the floor;
- flexible sheet heating elements for room heating (IEC 60335-2-96);
- room heaters (IEC 60335-2-30).
This third edition cancels and replaces the second edition published in 2002, its Amendment 1 (2007) and its Amendment 2 (2012). This edition constitutes a technical revision.
