Safety of household and similar electrical appliances - Part 47 : Particular requirements for electrical heating appliances for breeding and rearing animals
1 Scope
This clause of GB/T 4706.1-2024 is replaced by the following.
This standard deals with the safety 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.
This standard applies to the appliances with the rated voltage not more than 250 V for single-phase appliances and 480 V for other appliances.
Note 101: This standard applies to heating appliances used for livestock rearing and breeding that include an electrical motor.
Note 102: Attention is drawn to the fact that:
– for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;
– additional requirements may be specified by the national health authorities concerned.
Note 103: 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 (GB/T 4706.82);
– room heaters (GB/T 4706.23).

3 Terms and definitions
This clause of GB/T 4706.1-2024 is applicable except as follows.
3.1 Definitions relating to physical characteristics
3.1.9 Replacement:
normal operation
operation of the appliance as in normal use, in still air
3.5 Definitions relating to types of appliances
3.5.101
heat-radiating appliance
electrical heating appliance that conveys the effective heat mainly by radiation
Note: Appliances of this type that when operated under conditions of normal operation, have a temperature rise not exceeding 95 K, measured at the hottest point on the radiator, are considered to be heating plates for animals and not heat-radiating appliances.
3.5.102
heating plate for animals
appliance mainly intended to be fixed in stables or in chicken breeding units or intended to be laid on the floor
3.5.103
electrical sitting-hen
appliance placed on the floor that has feet or hiding-holes enabling chickens to hide under it, the chickens being warmed by an overhead heating plate
3.5.104
chicken breeding units
appliance for the breeding of chickens on several superposed levels
Note: It is usually equipped with heating plates above the chickens.
3.5.105
incubator
appliance designed for egg hatching
Note: It is usually equipped with heating elements for air warming and water evaporation, ventilators for air circulation and motors for agitating the eggs on the shelves.
