家用和类似用途电器的安全第2-79部分:高压清洁器和蒸汽清洁器的特殊要求

[中文适用范围]： 本部分涉及无牵引驱动的高压清洁器的安全性，适用于家用和商业室内或室外使用，额定压力不小于2.5 MPa且不超过35 MPa。 它也适用于蒸汽清洁器和热水高压清洁器的部分，这些部分具有不超过100升的容量，额定压力不超过2.5 MPa，且容量与额定压力的乘积不超过5 MPa·升。 它们不配备牵引驱动。以下驱动系统的动力系统包括： - 电源供电的电机，额定电压不超过250V（单相机器）或480V（其他机器）； - 电池供电的电机； - 内燃机； - 液压或气动电机。 本标准不适用于： - 额定压力超过35 MPa的高压水射流机器； - 家用液体或蒸汽清洁器（IEC 60335-2-54）； - 手持式和便携式电动工具（IEC 60745系列、IEC 61029系列、IEC 62841系列）； - 医疗用途的电器（IEC 60601）； - 农业喷雾器（ISO 4254-6）； - 非液体固体磨料清洁器； - 设计为生产流程一部分的机器； - 设计用于腐蚀性或爆炸性环境（粉尘、蒸汽或气体）的机器； - 设计用于车辆、船舶或飞机上的机器。 [外文原描述]： IEC 60335-2-79:2021 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60335-2-79:2021 deals with the safety of high-pressure cleaners without traction drive, intended for household and commercial indoor or outdoor use, having a rated pressure not less than 2,5 MPa and not exceeding 35 MPa. It also applies to steam cleaners and those parts of hot water high pressure cleaners incorporating a steam stage which have a capacity not exceeding 100 l, a rated pressure not exceeding 2,5 MPa and a product of capacity and rated pressure not exceeding 5 MPa·l. They are not equipped with a traction drive. The following power systems of the drive for the high pressure pump are covered: - mains powered motors up to a rated voltage of 250 V for single-phase machines and 480 V for other machines, - battery-operated motors, - internal combustion engines, - hydraulic or pneumatic motors. This standard does not apply to: - high pressure water jet machines having a rated pressure exceeding 35 MPa; - liquid or steam cleaners intended for domestic use (IEC 60335-2-54); - hand-held and transportable motor-operated electric tools (IEC 60745 series, IEC 61029 series, IEC 62841 series); - appliances for medical purposes (IEC 60601); - agricultural sprayers (ISO 4254-6); - non-liquid, solid abrasive cleaners; - machines designed to be part of a production process; - machines designed for use in corrosive or explosive environments (dust, vapour or gas); - machines designed for use in vehicles or on board of ships or aircraft. This fifth edition cancels and replaces the fourth edition published in 2016. It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition (minor changes are not listed): - editorial and technical alignment with IEC 60335-1:2020; - clarification on hand-held and battery-operated high pressure cleaners; - general editorial improvements. This part 2 is to be used in conjunction with the latest edition of IEC 60335-1 and its amendments. It was established on the basis of the sixth edition (2020) of that standard.
