家用和类似电器 - 安全 - 第2-4部分:旋转提取器的特殊要求

IEC 60335-2-4:2021 deals with the safety of stand-alone electric spin extractors and spin extractors incorporated in washing machines that have separate containers for washing and spin extraction for household and similar purposes that have a capacity not exceeding 10 kg of dry cloth and a drum peripheral speed not exceeding 50 m/s, their rated voltages being not more than 250 V for single-phase appliances and 480 V for other appliances. Appliances not intended for normal household use but which nevertheless may be a source of danger to the public, such as spin extractors intended to be used by laymen in shops, in light industry and on farms, and spin extractors for communal use in blocks of flats or in launderettes, are within the scope of this standard. As far as is practicable, this standard deals with the common hazards presented by appliances which are encountered by all persons in and around the home. 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, the national water supply authorities and similar authorities. This standard does not apply to: - appliances intended exclusively for industrial purposes; - 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). This seventh edition cancels and replaces the sixth edition published in 2008, Amendment 1:2012 and Amendment 2:2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - aligns the text with IEC 60335-1, Ed 5, and its Amendments 1 and 2; - replacement of the term definition of accessible part to include test probe 18; - addition of test probe 18 for accessibility of live parts. This part 2 is to be used in conjunction with the fifth edition of IEC 60335-1:2010 and its amendments.
