IEC 60335-2-103:2023 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60335-2-103:2023 EXV includes the content of the references made to IEC 60335-1:2020. IEC 60335-2-103:2023 deals with the safety of electric drives for horizontally and vertically moving gates, doors, garage doors and windows for household and similar purposes, their rated voltage being not more than 250 V for single-phase drives and 600 V for other drives including direct current (DC) supplied appliances and battery-operated appliances. It also covers the hazards associated with the movement of the driven part. Drives not intended for normal household use but which nevertheless can be a source of danger to the public, such as drives intended to be used by laymen in shops, offices, hotels, restaurants, hospitals, in industry and on farms, are within the scope of this standard. Requirements for drives for doors that can be used in emergency routes and exits are given in normative Annex AA. Examples of drives within the scope of this standard are drives for – folding doors; – revolving doors; – rolling doors; – roof windows; – sectional overhead doors; – swinging and sliding gates or doors. Drives can be supplied with a driven part. As far as is practicable, this standard deals with the common hazards presented by drives 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 drive safely without supervision or instruction; – children playing with the drive. 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, the national water supply authorities and similar authorities. This standard does not apply to drives – for vertically moving garage doors for residential use (60335-2-95); – for shutters covering doors and windows (including locations where the door is set back from the shutter), awnings, blinds and similar equipment (60335-2-97); – intended exclusively to be used by trained persons in commercial and industrial premises; – for specific purposes, such as fire doors; – for natural smoke exhaust ventilators not used as windows (ISO 21927-2); – intended to be used in locations where special conditions prevail, such as the presence of a corrosive or explosive atmosphere (dust, vapour or gas). This standard does not apply to movement of a pedestrian door where such movement is based solely on stored energy. This fourth edition cancels and replaces the third edition published in 2015, Amendment 1:2017 and Amendment 2:2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the text has been aligned with IEC 60335-1:2020; b) scope includes DC-supplied appliances and battery-operated appliances (Clause 1); c) some notes have been converted to normative text (Clause 1); d) additional requirements for installation instructions have been incorporated (7.12); e) application of test probe 18 and test probe 19 have been introduced (8.1.1, 20.2, Annexes BB, CC and DD); f) addition of surface temperatures for external accessible surfaces (11.3, 11.8); g) requirements for loading accessible appliance outlets and socket outlets have been added (11.7); h) requirements for appliances incorporating integral batteries or separable batteries have been added (11.7); i) requirements have been added for drives intended for permanent connection delivered with a connector to ease the installation (22.108, 24.101, 25.3). This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments unless that edition precludes it; in that case, the latest edition that does not preclude it is used. It was established on the basis of the sixth edition (2020) of that standard.
