GB 4706.60-2002/1EC 60335-2-43:1995IEC Preface
1)[EC (International Electrotechnical Commission) is a worldwide standardization organization consisting of all national electrotechnical committees (IEC National Committees). Its purpose is to promote international cooperation on all issues related to standardization in the electronic and electrical fields. There are also some additional activities in this area, such as the issuance of EC International Standards. The preparations for the publication of international standards are entrusted to technical committees. In this preparation process, any 1EC National Committee can participate in issues of interest. International, governmental and non-governmental organizations also participate in this preparation. EC and the International Organization for Standardization (ISO) follow closely the cases determined by the cooperation between the two organizations. 1) IEC has a close cooperation with the IEC, 2) IEC's formal technical resolutions or agreements are made by technical committees in which all national committees interested in these issues participate, and therefore, they represent and explain the international consensus on the issues involved as faithfully as possible. 3) [FC published standards, technical reports or guidelines for international use in a recommended manner and are accepted by national committees. 4) In order to promote international coordination, it is hoped that national committees will adopt this IEC standard in their own standards or regional standards when conditions permit. Any differences between national or regional standards corresponding to EC standards and this standard should be clearly pointed out in the latter.
5) IEC No procedure for the application of the approval mark has been established. IEC assumes no responsibility for the claim that certain equipment complies with an IEC standard. This standard has been prepared by IEC Technical Committee 61: "Safety of Household and Similar Electrical Appliances". IEC 60335-2-43, second edition, supersedes the first edition and amendments. This standard is based on the following documents:
61/865/D1S
Preliminary report
61/902/RVD
Full material on the adoption of this standard can be found in the voting report shown above. This standard is used in conjunction with the latest edition of IEC 60335-1 and its amendments. This standard is based on the third edition of IEC 60335-1 (1991).
This standard supplements and amends the corresponding provisions of IEC 60335-1, thus transforming it into an IEC standard: Safety requirements for clothes dryers and towel racks.
Clause of IEC 60335-1 not mentioned in this standard may be used as long as it is reasonable. Where "addition", "modification" or "replacement" is marked in this standard, the relevant clauses in this standard shall be modified accordingly. Note 1: The following fonts are used:
Requirements, printed.
Test procedures, italic.
Notes, lowercase printed.
Boldface words in the clauses are definitions given in Chapter 2. When the definition of IEC 60335-1 affects this standard, this standard and related words are in boldface. Note 2: The numbering of the clauses and figures added to this standard on the basis of IEC 60335-1 starts from 101. The following differences exist in some countries:
--Chapter 3: DC components are not allowed to be installed on the neutral conductor of the appliance (similar to Australia). — 11.101: If the warning is marked on the appliance, it may not be required for lower temperature rise limits (USA). — 19.13: The temperature rise of textiles shall not be measured (USA). — 24.101: Self-resetting thermal cut-outs are permitted if they have been demonstrated to be reliable (USA). 1 Scope
GB 4706. 602002/IEC 60335-2-43:1995 Safety of household and similar electrical appliances
Particular requirements for clothes dryers and towel racks This clause in GB 4706.1-1998 is replaced by the following: This standard applies to the safety of electric clothes dryers (which dry textiles by placing them on a rack and blowing air through them) and electric towel racks for household and similar purposes, with a rated voltage not exceeding 250 V. NOTE 1: Clothes racks may be fixedly mounted or free-standing in a cupboard. Appliances not intended for ordinary household use, where air circulation may be natural or forced, are included within the scope of this standard, provided that they are likely to present a danger to the public, for example appliances used by infirm persons in shops or used in light industry or on farms. As far as practicable, this standard deals with the common hazards presented by appliances which are encountered by the general public in and around the home. This standard does not normally take into account:
- appliances intended for use by children or unsupervised infirm persons; - appliances intended for children to play with.
NOTE 2 Attention should be drawn to the following facts:
- appliances intended for use in vehicles, ships or aircraft - additional requirements may apply where necessary; - appliances intended for use in tropical areas - special requirements may apply where necessary. In many countries additional requirements are laid down by national health authorities, national labour protection authorities, national water authorities and similar authorities. 3: This part does not apply to:
Appliances for industrial purposes
Appliances for use in special environments, such as those in which corrosive or explosive gases (dust, steam or gas) are present, - Drum dryers (GB 4706.20-2000). 2 Definitions
This clause in GB 4706.1-1998 is applicable except for the following. 2.2.9 This clause is replaced by the following:
Normal operation
The textile is placed on the rack or shelf and the appliance is operated according to the instructions in the instruction manual. The textile used is a double-layered, hemmed, unwashed cotton piece with a size of 70 cm × 70 cm and a mass of 140 B/m2 to 175 g/m2 in the dry state. Unless otherwise specified, the appliance has four layers of textile to support the heating surface of the textile. For appliances that rely on warm air to dry textiles, use a layer of textiles.
Note: In case of doubt, place the cotton piece at a temperature of (20 ± 5) °C and relative humidity of (60 ± 5)% for at least 24 hours. 3 General requirements

Note: The following dimensions are used to calculate the usable volume: - Height, the maximum distance between the topmost rack and the heating tray. Width, the length of the rack. Depth, the total horizontal distance between the outer racks. Then, the appliance should be subjected to the electrical strength test of 16.3 and inspected to see that there is no trace of water on the insulation that could reduce the creepage distance and electrical clearance to below the values specified in 29.1.

+B 4706.60--2002/1Et 60335-2-43:199519.2 This clause adds the following:
If the appliance has a heated surface that supports the fabric, use eight layers of fabric. For appliances that dry the fabric by blowing in warm air, place two layers of fabric on the protective grille of the heating element. If the heating element is located on the fabric, place it on top of the air inlet. Test with the grille or air inlet completely covered by the fabric, then test with 80% of the area of the grille or air inlet covered by the fabric.
Performance, or take into account the different positions of the fabric.
Appliances with vents are also tested with the motor stopped and the grille or air inlet uncovered. Appliances with heating means located above fabric are also tested with two layers of fabric placed on a shelf. The shelf is raised 50 mm above the normal position or the maximum distance allowed by the structure, whichever is the less. Appliances mounted in walls that can be folded for storage are also tested, but the shelf is folded and without fabric. 19.13 This clause adds the following:
The temperature rise of the fabric shall not exceed 150 K.
The fabric shall not show obvious scorching.
