家用和类似用途电器.安全.第2-106部分:安装在可拆卸地板覆盖物下的加热地毯和房间加热装置的特殊要求

[中文适用范围]： 本部分IEC 60335处理的是以下设备的安全：便携式加热地毯；加热地毯及类似设备；用于加热所在房间的加热单元，其设计安装于可移除地板覆盖物（如地毯、缓冲乙烯基或松散铺设的层压板）正下方。其额定电压对于单相安装不超过250 V，对于其他安装（包括直流供电设备）不超过480 V。 [外文原描述]： IEC 60335-2-106:2021 deals with the safety of - portable heated carpets; - heated carpets and similar appliances; - heating units to heat the room in which they are located and that are intended to be installed directly under materials used as a removable floor covering such as carpet, cushion vinyl, or loose laid laminate, their rated voltage being not more than 250 V for single-phase installations and 480 V for other installations, including direct current (DC) supplied appliances. Attention is drawn to the fact that - in many countries different wiring rules apply; - 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 authorities for fire protection, the national authorities for building regulations, the national health authorities, the national authorities responsible for the protection of labour 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); - blankets, pads and similar flexible heating appliances (IEC 60335-2-17); - heated mats and foot warmers with an area not exceeding 0,5 m2 (IEC 60335-2-81); - flexible sheet heating systems permanently incorporated in the floor of the building structure (IEC 60335-2-96); - flexible heating elements incorporated in other appliances; - battery-operated appliances. This second edition cancels and replaces the first edition published in 2007. 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) some notes have been converted to normative text (Clause 1, 5.2, 5.3, 5.6, 7.12.1, 7.101, 10.1, 18.101.1, 18.101.2, 18.102.5, 19.1, 19.103, 21.1, 21.104, 21.105, 30.102); c) requirements for portable heated carpets have been added (Clause 1, 5.2, 5.5, 6.1, 6.2, 7.1, 7.6, 7.12, 7.14, 7.101, 11.8, 15.1, 15.101, 16.1, 16.2, 16.3, 19.101, 19.102. 19.103, 21.105, 21.106, 24.1.5, 24.2, 29.3); d) requirements for washable portable heated carpets have been added (5.3, 7.1, 7.6, 7.12, 7.14); e) the test of 30.102 has been updated. 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.
