APPENDIX This section N is normative.

This section was proposed by China Light Industry Federation.

This part of the jurisdiction of the National Standardization Technical Committee appliances (SAC/TC46).

This part was drafted. Beijing Institute of mechanical services, Yu Fu-kitchen equipment (Shenzhen) Co., Ltd., Beijing Huamei cooking Machinery Co., Ltd., Guangzhou City, Guangdong Huadu District, Western Kitchen Equipment Factory, Beijing Silver Valley Electrical Co., Ltd., on the Hai Haike Hotel Equipment Manufacturing Co., Ltd., Beijing Industry and Trade Co., Ltd. with a new, Foshan Electrical Factory Conway.

Introduction

It has been assumed in the drafting of this section, a person appropriately qualified and experienced to implement the provisions of this section.

This portion is recognized that the use of household electrical appliances and the like under normal conditions noted when the manufacturer's instructions for the appliance an acceptable level of risk international protection of electrical, mechanical, thermal, radiation and fire, it also includes the use may be expected to occur Abnormal circumstances, and in view of electromagnetic interference affects the way for the safe operation of the appliance.

In developing this part has been as much as possible into account the requirements of GB 16895 in order to make electrical appliances when connecting to the grid Gas wiring rules requires coordinated.

If a number of functions GB 4706 appliance involves special requirements in different part of the special requirements, as far as is reasonable in the circumstances Under the special requirements of the relevant standards should be applied to each function separately. If applicable, taking into account the influence of one function to other functions.

When the special requirements not included in Part 1 of the appended claims when hazardous, Part 1 applies.

Note 1.The meaning of the special requirements of the Technical Committee has decided there is no need to redefine the general requirements for special requirements.

This part is a matter of security appliance product family standards, and standards covering the same subject at the same level in the same category in priority.

Note 2.When the application GB 4706 series of standards on general requirements and specific requirements covering the risk of the same level and the same standard does not apply to categories already General Requirements section has been taken into account. For example, in regard to many of the requirements for the surface temperature of the appliance, similar standards, such as ISO 13732-1 on heat Surface requirements, except for the part not applicable to the standard 1 or special requirements.

An appliance that complies text of this section, when examined and tested, found to have other features that will be covered by the requirements of this damage and when the level of security, it will not be considered to comply with the safety guidelines in this section.

Product use various materials or various forms of structures other than specified in this part, this may be the product according to the present section the intent of these requirements for inspection and testing. If found to be substantially equivalent, it can be determined which comply with this part.

GB 4706.37-2008/IEC 60335-2-38:2002 Household and similar electrical appliances - Safety Particular requirements for commercial electric griddles of Range 1 GB 4706.1-2005 in this chapter replaced by the following.
