[中文适用范围]： IEC 60884-2-7:2025 RLV 包含官方 IEC 国际标准及其 Redline 版本。Redline 版本仅提供英文版，可让您快速轻松地比较官方 IEC 标准与其先前版本之间的所有更改。IEC 60884-2-7:2025 适用于可重新接线和不可重新接线的电线延长线组，带或不带接地触点，额定电压大于 50 V 但不超过 440 V，额定电流不超过 16 A，用于家庭和类似用途，室内或室外。本文件不适用于带有卷绕装置的电线延长线组。IEC 60884-2-8 还涵盖了用作家具插座的电线延长线组。本文件还适用于用于电缆卷筒的电线延长线组，因此它们成为带有可拆卸柔性电缆的电缆卷筒。对于电源线延长装置的组合，IEC 61242 的卷轴要求和测试也适用。电源线延长装置适合在环境温度通常不超过 +40 °C 的情况下使用，但其 24 小时平均温度不超过 +35 °C，环境空气温度下限为 −5 °C。第二版取消并取代了 2011 年发布的第一版和修订 1:2013。此版本构成技术修订。此版本与上一版相比包括以下重大技术变化：a) 与 IEC 60884-1 第四版保持一致。 [外文原描述]： IEC 60884-2-7:2025 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 60884-2-7:2025 applies to cord extension sets, rewirable and non-rewirable, with or without earthing contact, with a rated voltage greater than 50 V but not exceeding 440 V and a rated current not exceeding 16 A, intended for household and similar purposes, either indoors or outdoors. This document does not apply to cord extension sets with means for reeling. Cord extension sets intended to be used as socket-outlets for furniture are additionally covered by IEC 60884‑2‑8. This document also applies to cord extension sets which are intended to be used in a cable reel, and which therefore become cable reels with a detachable flexible cable. For the combination of the cord extension set, the reel requirements and tests of IEC 61242 apply in addition. Cord extension sets are suitable for use at ambient temperatures not normally exceeding +40 °C, but their average temperature over a period of 24 h does not exceed +35 °C, with a lower limit of the ambient air temperature of −5 °C. This second edition cancels and replaces the first edition published in 2011, and Amendment 1:2013. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) alignment to IEC 60884-1, fourth edition.
