Foreword

All the contents of this part are mandatory. This part shall be used in conjunction with GB 4706.1-2005 "Household and similar electrical appliances - Safety - Part 1. General requirements" and its revisions. In this part, the part which is "applicable" indicates that the corresponding provisions in GB 4706.1-2005 apply to this part; the part which is "replaced" or "modified" shall be based on this part; the part which is "added" indicates that it shall, in addition to the corresponding provisions of GB 4706.1-2005, also comply with the provisions added in this part. This part replaces GB 4706.29-1992 "Safety of household and similar electrical appliances - Particular requirements for electromagnetic cookers". The main differences between this part and GB 4707.29-1992 are as follows: 1) The name of the part and the applicable product are different. This part is entitled "Particular requirements for portable induction cooker", which defines that the applicable products are applicable portable induction cooker, and the non-portable induction cooker shall be tested in accordance with the requirements of GB 4706.22; GB 4706.29-1992 also applies to non-portable induction cookers; 2) In this part, it adds the normative references in Clause 2; 3) In this part, it clearly defines the test container, load, test method, etc. (3.1.9); 4) In this part, it introduces relevant definitions in Clause 3 (3.101 ~ 3.104); 5) This part defines that portable induction cookers shall be tested in accordance with the requirements of motor-driven appliances (5.101). The provisions of GB 4706.29-1992 stipulate that Clause 10 shall be tested as the requirements of motor-driven appliances, and Clause 11 shall be tested as electric appliances. 6) Clause 13 requirements and test methods are different; 7) The requirements and test methods for Clause 15 overflow tests are different (15.2); 8) Clause 16 requirements and test methods are different; 9) In this part, it cancels the durability test (Clause 18 does not apply); Household and similar electrical appliances - Safety - Particular requirements for portable induction cooker

1 Scope

GB 4706.29-2008 is the Chinese national standard on household and similar electrical appliances-safety - particular requirements for portable induction cooker, in the field of domestic and commercial equipment, entertainment, sport. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 31 December 2008 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 February 2010. Classification: ICS 97.040.01, CCS Y63. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This clause of GB 4706.1-2005 is replaced by the following. This part is applicable to portable induction cookers for household and similar purposes the rated voltage of which does not exceed 250 V. The electromagnetic heating part in gas and electric combined household and similar cookers shall comply with this part. Practically speaking, this part deals with the usual dangers posed by appliances that are encountered by all persons in and around the residence. However, this part generally does not consider. - The use of appliances by unsupervised young children and disabled persons; - Children play with the appliance.

Note 1. Note the following. - Some additional requirements may be required for appliances intended for use on vehicles, ships or aircraft; - In many countries, the additional requirements are regulated by the national health care department, the department responsible for labor protection, the national water supply department and similar departments. - For measurements involving electromagnetic compatibility and electromagnetic radiation, it requires to refer to relevant standards.

Note 2. This part does not apply to. - Appliances used in special environments, such as corrosive or explosive environments (dust, vapor or gas); - Appliances intended for commercial use (but some of the requirements can be referred to by these devices); - Microwave oven (GB 4706.21); The hotplate which heats at least one metal container by eddy current.

Note 1. Eddy currents are induced at the bottom of the vessel by the electromagnetic field of a coil.

3.102 Induction cookers A portable appliance equipped with at least one induction hotplate.

3.103 Cooking zone The indicated area on the surface of the appliance where the container is placed when heating the food.

Note. When a hotplate projects from the induction hotplate, the surface is the cooking area.

3.104 Touch control A controller that is started by the contact or proximity of a finger while the contact surface moves little or not at all.

4 General requirements

This clause of GB 4706.1-2005 is applicable.

5 General conditions of test

This clause of GB 4706.1-2005 is applicable except as follows:

Note 101. If the test of

15.101 is required, it needs to add three samples.

5.3 ADD. If it is clear from the structure of the appliance that a functional test is not more severe than the test of another function, the test of this function does not need to be carried out.

5.6 ADD. For appliances with appliance receptacles and appliances partially or completely immersed in water during cleaning, the instructions shall state that the connector must be removed from the appliance before cleaning and the appliance receptacle must be wiped dry before the appliance is used again. For appliances that use connectors with temperature controls, the instructions shall state that they must be used with the mating connector. For appliances intended for outdoor use, the instructions shall include the following. - Appliances suitable for outdoor use; - It is necessary to check the power cord regularly for damage. Do not use the appliance if the power cord is damaged. - The appliance must be powered by a residual current breaker (RCD) rated at no more than 30 mA; - The appliance shall be connected to a socket with a grounding pin (for category I appliances). For appliances with non-working accessible metal surfaces that have a temperature rise of more than 90 K as mentioned in clause 11, the instructions shall include the following. During the operation of the appliance, certain surfaces are very hot. If the appliance is marked with the symbol of IEC 60417-5041 (DB. 2002-10), the instructions shall indicate that the surface will become hot during use.
