家用和类似用途电器设备. 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]： 第 1 部分的本条款由以下内容取代。 IEC 60335 的这一部分涉及不带牵引驱动装置的高压清洁器的安全性，适用于家庭和商业室内或室外使用，额定压力不低于 2.5 MPa 且不超过 35 MPa。 [外文原描述]： 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.
