GB4706 This part deals with the safety of electric clocks with a rated voltage not exceeding 250V, and also deals with the common dangers encountered by all people in the room or around the house caused by electrical appliances. It does not apply to battery-driven clocks, clocks for "automatic timing" purposes, clocks equipped with only electronic circuits, etc. GB 4706.70-2003 Safety of household and similar electrical appliances Particular requirements for clocks GB4706.70-2003 standard download decompression password: www.bzxz.net

G4706 This part of the technical content is mandatory, GR 4705.70-2003/IEC: 60335-2-26: 1994 This part also adopts IEC63335-2-26, 1994 Safety requirements for household and similar electrical appliances. This part should be combined with GF47: Fi.-1998 Safety requirements for household and similar electrical appliances (rr: TF: f133j-11991 and its first supplement). Part of this part is the National Standardization Technical Committee for Household Electrical Appliances. This part is drafted by: National Electrical Appliance Research Institute, and some participants: China Certification Center Jinan New Era Electronics Co., Ltd. This part mainly includes the following sections: 4706, 70-2003/[E: 60535-2-26:1994 IEC Foreword
) International Standardization Organization (International Standardization Organization) is composed of all national committees (national committees). The purpose of IEC is to promote the full cooperation of all countries in the field of electrical and electronic standardization. In view of the above and taking into account the needs of their activities, this International Standard has been published. The work of formulating is completed by the Technical Committee. Any IEC National Committee that is willing to take a special interest in this topic can participate in the formulation work. According to the agreement between IEC and IS, they have a separate cooperative relationship in the three-way cooperation.
21 IEC technical decisions or preliminary proposals are made by the National Committees that have a particular interest in the subject and, as far as possible, express international consensus on the subject. 3) These decisions or preliminary proposals are made in the form of international standards, which are made available for international use in the form of reports or observations and are recognized by the National Committees in this document.
4) IEC helps National Committees to adopt standards within the scope of their national conditions. If there are differences in national standards or regional standards, they should indicate this clearly in their national standards as far as possible. 5) The marking sequence indicates that they have recognized the equipment, but it does not mean that the equipment is not in compliance with a certain standard. [Chapter 6] [Electrical equipment for household and similar use] This standard consists of: 1F0335 The first edition of F60335-:1991 replaced the second edition. This standard is based on the following documents: 1991-2-751-1991. The first edition of F60335-:1991 was revised and replaced by the second edition of F60335-:1991. The content of this standard is supplemented and prohibited by the corresponding clauses of F60335-:1991.
If there are special terms in the "material" part that are not mentioned in the "second part", the "first part" clauses can be used reasonably: if the "addition", "modification" or "replacement" in this standard is used, the corresponding force penetration in the first part must be modified accordingly. Note: The following is printed in the standard:
