GB ​​4706. 59-2002/IEC 60335-2-52:1994IEC Foreword
1) IEC (International Electrotechnical Commission) is a worldwide standardization organization consisting of all national electrotechnical committees (IEC National Committees). Its goal is to promote cooperation between national standards on all issues related to standardization in the electronic and electrical fields. There are also some other additional activities, such as issuing EC international standards. The preparation for publishing international standards is entrusted to technical committees. In this preparation process, any IEC National Committee can be interested in the issue, and international, governmental and non-governmental organizations also participate in this preparation. 1) IEC and the International Organization for Standardization (ISO) work closely together under the terms of the agreement between the two organizations. 2) IEC's formal technical resolutions or agreements are made by technical committees in which all national committees interested in these issues participate. Therefore, they can represent and explain the international consensus on the issues involved as much as possible. 3) The standards and technical reports published by IEC are adopted in the form of guidelines and recommendations for international application and are accepted by national committees. 4) In order to promote international coordination, IEC hopes that national committees, when conditions permit, should adopt the international standards or regional standards. This IEC standard is used. Any differences between the national or regional standards corresponding to the IEC standard and this standard should be clearly indicated in the latter.
5) IEC does not provide an approval process for marking its standards, nor is it responsible for proposing that any equipment complies with the standard. This standard was prepared by 1EC Technical Committee 61 (Safety of Household and Similar Electrical Appliances). IEC60335-2-52, second edition, replaces the first edition. This standard is based on the following documents:
61(CO)783
Voting Report
61(CO)797
Regarding the standard promotion method All the materials can be found in the voting report in the table above. This standard is used in conjunction with the latest version of IEC60335-1 and its amendments. This standard is based on the third edition of IEC60335-1 (1991).
This standard supplements and modifies the corresponding clauses of IEC60335-1, thereby transforming it into an IEC standard: Safety requirements for electric oral hygiene appliances.
The clauses of TEC60335-1 not mentioned in this standard may be used as long as it is reasonable. Where the clauses in this standard are marked with "addition", "modification" or "replacement", the relevant clauses in this standard are modified accordingly. Note 1, the following fonts are used:
-Requirements: print,
Test procedures: italics;
Explanations: lowercase print.
The boldface in the text is the definition given in Chapter 2. When the definition of TEC60335-1 affects this standard, this standard and the associated words are in boldface.
NOTE 2 The clauses and figures added to this standard on the basis of IEC 60335-1 are numbered starting from 101. The following differences exist in some countries:
Chapter 3: Restricted DC components in the neutral conductor of appliances (Australia). -6.1: Class 0 appliances and hand-held Class 0 parts are allowed (Japan). -6.1 replaces this clause which is not applicable (USA). -7.1.12.1: Additional instructions are required (USA). -19.101: The test is different (USA). 1 Scope

Particular requirements for oral hygiene appliances
This chapter in GB4706.1-1998 is replaced by the following: This standard applies to the safety of electric oral hygiene appliances for household and similar purposes, with a rated voltage not exceeding 250 V. NOTE 1 Examples of appliances covered by this standard are: - toothbrushes - oral irrigators. As far as is practical, this standard addresses common hazards presented by appliances that people encounter in and around the home. This standard does not normally consider: - appliances used by children or unsupervised infirm persons; - appliances intended for children to play with. NOTE 2 Attention should be drawn to the following facts: - appliances used in vehicles, ships or aircraft may require additional requirements, and - appliances used in tropical areas may require special requirements. - in many countries, additional requirements are prescribed by national health authorities, national labour protection authorities, national water and energy authorities and materials authorities. NOTE 3 This standard does not apply to appliances for medical purposes (IEC 60601). 2 Definitions This clause of GB 4706.1-1998 applies except as follows. 2.2.9 The system is operated under the following conditions:
Normal operation
The device is operated under the following conditions:
The oral irrigator is a container filled with water at a temperature of about 45°C, and operates at the water level specified in the instruction manual. If there is no specification in the instruction manual, the container is filled at the highest water level. The other devices operate under no load.

A small hole of 0.8 mm in diameter is punctured in a rubber hose with a needle. A small hole of 0.5 mm in diameter is punctured in a thermoplastic hose with a heated needle. Care is taken not to enlarge the hole. Note: When reassembling the appliance, silicone rubber may be used as a sealant to ensure that the joint is watertight. The appliance is filled with a 1% aqueous solution of NaCl and operated in accordance with clause 11. During the last cycle, the water pressure in the hose is increased to maximum by locking the outlet or by adjusting the control device to increase the pressure. The water pressure is reduced to normal.
