IEC Foreword
1) IEC (International Electrotechnical Commission) is a worldwide standardization organization composed of all national electrotechnical committees (IEC National Committees). The purpose of IEC is to promote comprehensive cooperation among countries in the field of electrical and electronic standardization. In view of the above purposes and taking into account the needs of other activities, IEC also publishes international standards. The entire formulation work is completed by the committee. Any IEC National Committee that is particularly interested in this technical issue can participate in the standard formulation work. According to the agreement reached between the IEC and ISO organizations, they have a close cooperative relationship in their work.
2) IEC resolutions or agreements on technical issues are formulated by technical committees participated by all particularly interested national committees, and try to express the international consensus on the issues involved. 3) These resolutions or agreements are for international use in the form of standards, technical reports or rules, and are recognized by national committees in this sense.
4) In order to promote international unification, IEC National committees are encouraged to adopt the contents of IEC standards as their national standards to the extent that national conditions permit. Differences between IEC and corresponding national or regional standards should be clearly indicated in the national standards as far as possible. 5) IEC has established a procedure for its recognition without marking, but does not assume any responsibility for the claim that a device conforms to a standard. 6) As far as possible, attention should be paid to the fact that some elements of this standard may be subject to patent rights. IEC does not take any position on any patent rights. This standard was prepared by Technical Committee 61 "Safety of Household and Similar Electrical Appliances" and is the first edition of IEC 60335-2-84.

The steel needle is applied in this way: a force of (10±0.5)N is applied along its axial direction, and the scratch is formed by dragging the steel needle along the coating surface at a speed of about 20mm/s. Make 5 scratches with a spacing of at least 5mm and the scratches at least 5mm from the edge. After the test, the appliance should not have damage that does not meet the requirements of this standard, especially Chapter 8 and Chapter 27 should meet the requirements of the standard.
