) The International Electrotechnical Commission (IEC) is a global standardization organization composed of the member countries' National Committees: IEC's mission is to promote international cooperation on all matters relating to standardization in the electronic field. For this purpose, IEC, in addition to other activities, also publishes International Standards. The preparation of these standards is entrusted to technical committees. Any National Committee interested in any point of question may participate in this work. International organizations with which it has a connection, governmental agencies and non-governmental organizations may also participate. ISO cooperates with the International Electrotechnical Commission on the terms and conditions of the agreement between the two organizations. 2) All technical correspondence concerning the work of the National Committees shall be addressed as close to the surface as possible. 3) All decisions or agreements on technical issues concerning the work of the National Committees shall be taken. To achieve a general view on the international effectiveness of the issues involved. 3) The standards, technical reports or registrations issued by other departments are made available to the international working group in the form of recommendations and are accepted by the national committees in this sense. 4) In order to promote international uniformity, the responsible national committees of IEC countries shall, as far as possible, incorporate the IEC international standards into national and regional standards. There should be no discrepancy between the IEC international standards and the corresponding national and regional standards. This should be clearly stated in the national and regional standards. 5) IEC does not provide recognition marks nor does it make any claims for equipment that conforms to its standards. This part of the standard is related to IEC Part 61E "Safety of electrical appliances for household and similar purposes" and Part 61E "Commercial electrical appliances for food processing!"
