scope:

Commented versions are a valuable improvement upon the conventional IEC Redline Version (RLV). These versions are designed to facilitate a clearer understanding of the revisions made between the prior and current editions of a publication. This enhanced product package incorporates both the most recent edition of the document and the annotated redline version. This combined offering provides users with an easily accessible means to track and comprehend the alterations and additions that have been made, thereby enhancing the utility and effectiveness of the publication for its intended audience. 

This part of IEC 60335 deals with the safety of electric blankets, pads, clothing and other flexible appliances that heat the bed or human body, for household and similar purposes, their rated voltage being not more than 250 V including direct current (DC) supplied appliances and battery-operated appliances.

This standard also applies to control units supplied with the appliance.

Appliances not intended for normal household use but which nevertheless possibly pose a source of danger to the public, such as appliances intended to be used in beauty parlours or by persons in cold ambient temperatures, are within the scope of this standard.

Requirements and tests for clothing are given in normative Annex CC.

As far as is practicable, this standard deals with the common hazards presented by appliances that are encountered by all persons in and around the home. However, in general, it does not take into account

- persons (including children) whose

• physical, sensory or mental capabilities; or

• lack of experience and knowledge prevents them from using the appliance safely without supervision or instruction;

- children playing with the appliance.

Children are considered to be old enough to use an appliance without supervision when they have been adequately instructed by a parent or guardian and are deemed competent to use the appliance safely.

Attention is drawn to the fact that

- for appliances intended to be used in vehicles or on board ships or aircraft, additional requirements can be necessary;

- in many countries, additional requirements are specified by the national health authorities, the national authorities responsible for the protection of labour and similar authorities.

This standard does not apply to

- appliances intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas);

- rigid bed warmers, such as those of metal or ceramic material;

- water bed heaters (IEC 60335-2-66);

- heating appliances for breeding and rearing animals (IEC 60335-2-71);

- foot warmers and heating mats (IEC 60335-2-81);

- appliances specifically intended for use under medical supervision (IEC 60601-2-35);

- heated carpets (IEC 60335-2-106).
