家用和类似用途电器的安全第2-66部分:水床加热器的特殊要求

This pack contains IEC 60335-2-66:2025 EXV and IEC 60335-2-66:2025 RLV. IEC 60335-2-66:2025 deals with the safety of electric water-bed heaters and their associated control units, for household and similar purposes, their rated voltage being not more than 250 V, including direct current (DC) supplied appliances. Appliances not intended for normal household use, but that nevertheless can be a source of danger to the public, such as appliances intended to be used in hotels, are within the scope of this standard. 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. Attention is drawn to the fact that – for appliances intended to be used in vehicles or on board ships or in 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 – for medical purposes (IEC 60601 series); – intended for immersion in water during use. This third edition cancels and replaces the second edition published in 2002, Amendment 1: 2008 and Amendment 2:2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment with IEC 60335-1:2020; b) conversion of some notes to normative text (Clause 1, 19.4, 22.101); c) clarification of requirements for remote operation (22.40, 22.49, 22.51). 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.
