1.1 International Electrotechnical Commission: It is the international body for standardization composed of national electrotechnical committees (National Electrotechnical Committees). It is the body that cooperates with the international community in standardization on all matters relating to the electrical field. To this end, in addition to its own activities, it develops International Standards, the preparation of which is entrusted to technical committees. All national committees with an interest in the standards to be prepared may join in the preparation of the standards. In accordance with the principles of practicality, 1.1 International Electrotechnical Commission: It is the international body for standardization composed of national electrotechnical committees (National Electrotechnical Committees). It is the body that cooperates with the international electrotechnical committees in the preparation of standards. 1.1 The International Electrotechnical Commission ... The relevant national committees of the country concerned shall participate. 5. The above decisions or amendments shall be recommended for use in the form of standards, technical reports, technical specifications or guidelines and shall be accepted by the national committees in this regard. 4. In order to promote the unification of international standards, the national committees should clearly indicate the region and the maximum extent possible for the conversion of international standards into national standards. Special attention should be paid to any regional standards and any guidelines should be clearly stated in the national standards. When a device is claimed to comply with a certain standard, please be aware that some ingredients in this international standard may be the subject of patents. No patent is sought to confirm that any ingredient is covered by this standard.
IECS03 This part of IEC 61/2177/F1S "Safety of household and similar electrical appliances". This standard replaces the first edition published in 1991 and has been revised once since 1996. This part of IEC 61/2177/F1S has been revised once since 1996. The following document is the latest international standard. Detailed information on the voting process for this standard is available in the attached document. This standard is based on the fourth edition (20) of IEC 61/2177/F1S and its entirety. Note: The "first part" mentioned in this standard refers to the relevant part of IEC 61/2177/F1S. The clauses should be supplemented and modified to convert the safety requirements of the unmanned heater into an environmental standard: All the requirements in the first part that are not specifically mentioned in this standard should be reasonable, that is, they should be used. This standard specifies "single addition", "modification" or "replacement", and the relevant contents of the first part should be modified accordingly. Note 2: The following clauses are numbered from 10:
Except for the design in the new case or the first part of the dream and the design, the design starts from 0". The notes in the clauses or the series are as follows:
The following examples are recorded in the text of the requirements. The words in bold are printed in the text, and the definitions are given in the third special clause. When a definition involves a term, the term and the related terms are also included in this publication.

In the first section, it is indicated that no assumptions have been made and the implementation of the functions within this standard is entrusted to appropriately qualified and experienced persons: This standard recognizes that the hazards such as electrical, thermal, fire and radiation hazards caused by normal use of the equipment are only considered to be avoided under the conditions specified in the manufacturer's instructions. This standard covers all abnormal conditions that can be foreseen in reality. This standard gradually considers the requirements of TF1235-2 as possible, so that the wiring specifications are not the same when the equipment is connected to the power supply: However, the wiring specifications of various countries are different, and this standard contains other features than those required by the first part of C60335: All the requirements of the other standards are required by the relevant part of the standard as long as they are consistent or applicable to the respective functions. If the effect of one function on another is also considered, the standard shall prevail over the standards covering the same level and category. If the personnel who certify the product conformity with this standard find that there are no other characteristics that are not covered by the requirements during the inspection and testing, then the product conformity with this standard shall be based on the safety principle of this standard. If the materials and structural forms used in the product are different from those specified in this standard, then the product can be inspected and tested according to the intent of these requirements. If the changes are substantially equivalent, it can be considered to meet the standard. Scope
GD 47C6.77—2004/1RL 60335-2-74;2002 Safety of household and similar electrical appliances Particular requirements for portable immersion heaters 4 This standard consists of the following: The safety of portable immersion heaters of adequate rated capacity are not intended for use with similar household purposes. However, small appliances may still cause danger to the public, for example appliances used by non-professionals in shops, businesses and on farms are also within the scope of this standard. After practical improvement, the quality of this standard and the advice given by this standard are such that the ordinary hazards present are likely to be encountered by all persons in residential and fixed-use environments.
