Introduction of GB/T 4706.37-2024

GB/T 4706.37-2024 Safety of household and similar electrical appl liances - Part 37: Particular requirements for commercial electric griddles and griddle grills 1 Scope This clause of Part 1 is replaced by the following. This document deals with the safety of electrically operated commercial griddles and griddle grills not intended for household use and similar use. This document applies to electrically operated commercial griddles and griddle grills not intended for household use and similar 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. Note 101: These appliances are used for the commercial processing of food, for example in kitchens of restaurants, canteens, hospitals and in commercial enterprises such as bakeries, butcheries, etc. 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. 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 may be necessary; ——in many countries additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour, the national water supply authorities and similar authorities. 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); ——appliances for continuous process appliances for the mass production of food; ——grillers and toasters (GB/T 4706.39); ——appliances incorporating induction heating sources. 2 Normative references This clause of Part 1 is applicable except as follows.

Stepped controls are set to the first position that gives a temperature equal to or greater than 275 °C. Cycling controls are set so that the mean value of the temperature over the cycle is 275 °C ± 5 °C. If this temperature cannot be reached, the control is set at the maximum. Griddle grills are operated open or closed whichever is the more unfavourable. When in the closed position, the plates are separated by a heat-resistant low-conductivity spacer panel 10 mm thick and having an area equal to the smaller of the cooking areas of the two heating plates. For griddle grills where both plates are not separately controlled, the control is adjusted so that the conditions set out above are achieved on the directly controlled plate. Where both plates are separately controlled, the conditions set out apply to both plates. Motors incorporated in the appliance are operated in the intended manner under the most severe conditions that can be expected in normal use taking into account the manufacturer's instructions. 3.101 griddle an appliance intended to cook by direct contact between one side of the food and a heated surface 3.102 griddle grill an appliance intended to cook by direct simultaneous contact of both sides of the food with two heated surfaces 3.103 installation wall a special fixed construction containing supply facilities for appliances installed in conjunction with it 3.104 heating unit any part of the appliance that fulfils an independent cooking or heating function 3.105 functional surface surface that is intentionally heated by an internal heat source and has to be hot to carry out the function for which the appliance is intended Note: An example is the heated sheath of a tubular heating element. 3.106 adjacent surface surface adjacent to a functional surface and which can become hot through conduction 4 General requirement This clause of Part 1 is applicable.
