1) The IEC International Committee (IEC International Committee) is an international standardization organization composed of all national electrotechnical committees (IEC and national committees). Its purpose is to promote international cooperation on standardization issues related to electricity and electronics. To this end, IEC conducts international standardization activities and publishes international standards. The preparation of these standards is entrusted to various technical committees, and any TF national committee interested in the work can participate in the preparation work. International, governmental and non-governmental organizations related to IEC can participate in this work. IEC and the International Organization for Standardization (IS 1) The two sides will work closely together on a regular basis. 2) All national committees with special interests in the issue will issue formal resolutions or agreements on IEC technical issues formulated by the technical committees in spring, which will represent the most sensitive opinions on the relevant issues in practice. 3) These formal resolutions and agreements are published in the form of standards, technical reports or public procurement, recommended for international adoption, and accepted by all user committees.
》 In order to obtain international consensus, the national committees are responsible for making the greatest possible use of IEC international standards in their national and regional standards. The differences shall be clearly indicated in the latter. 1. 5) IEC has not established a procedure for the recognition of the marking. When a device claims that it complies with a certain frequency standard of IEC, it shall be subject to the same responsibility.
This standard was prepared by IEC Technical Committee No. 61 (Safety of Household and Similar Electrical Appliances): This standard is the first edition of IEC 60335-2-73. This standard is based on the following documents:
