1) The International Electrotechnical Commission (TEC) is a global standardization organization composed of the member countries' electrotechnical committees (TBCs: national committees). Its main mission is to promote international cooperation on issues related to standardization in the electrical and electronic fields. For this purpose, in addition to other activities, EC also publishes international standards. The formulation of international standards is entrusted to technical committees: any IEC national committee that is interested in the issues involved can participate in this work, and international organizations, government agencies and non-governmental organizations that are affiliated with the TFC can also participate. The IEC and the International Organization for Standardization (ISC) are closely linked under conditions determined by agreement between the two organizations. 2) The formal decisions or motions of the Technical Committee on the technical issues concerned shall be taken by representatives of all the National Committees concerned, in order to achieve as close as possible to international consensus on the issues involved. 3) The standards and technical reports produced shall be submitted for international use in the form of recommendations and accepted by the National Committees concerned.
4) In order to promote international uniformity, the IEC National Committees shall, as far as possible, submit IFC International Standards to the relevant national and regional standards. Any inconsistency between the standard and the corresponding national or regional standards shall be clearly indicated in the national or regional standard.
5) IEC does not provide for the endorsement of any standard and shall not be liable for any equipment claiming to conform to one of its standards. 6) Noting that some components of this International Standard may be the subject of patent rights, IEC shall not be responsible for identifying any or all such patents.

Accidental tilting from any position shall be prevented, even in the event of power failure. There shall be no joint area between inclined parts and the appliance, except at the screw end when the part is fully inclined.
GB 4706.38—2003/IEC 60335-2-64;1997 Compliance is determined by inspection, manual test and disconnection of the appliance at any time during the tilting movement. Any of the following methods may meet this requirement: The switch to be supplied must be kept connected; - Limit () m/
- Protect the danger zone with appropriate guards! - Keep the moving parts in the correct position, that is, in the absence of a mountain. If artificial objects or equipment are used for tilting, except for intentional use of the section In addition, there is the possibility of adverse effects of unpaired oblique movements. Whether it is qualified can be determined by inspection and connection. A force of 34° can be applied to any point on the belt to determine whether it is qualified. 20.1 The moving parts should be adequately protected by safety partitions or non-driven protective parts and/or barriers in the moving parts area, unless these moving parts are fully spring-loaded. The maximum manpower is 50°, and an emergency switch device is provided. The upper two spokes are at least 0 mm apart.
