[中文适用范围]： IEC 60730-2-24:2026 EXV 包含国际标准及其扩展版本（EXV）。该官方 IEC 标准的扩展版本仅以英文提供，内容全面完整。IEC 60730-2-24:2026 EXV 纳入了对 IEC 60730-1:2022 的引用内容。 IEC 60730-2-24:2026 适用于家用及类似用途设备中所用、所配或与之一体使用的自动位移式电气控制装置。 注1：本文档中，“控制”一词特指“位移式电气控制”。 示例1：gross 体积不超过 25 升、工作压力在 4 kPa 至 150 kPa 之间的电压力 cooker 中所使用的位移式电气控制装置。 适用条件包括： - 采用交流或直流供电，额定电压不超过 690 V AC 或 600 V DC 的控制系统； - 用于、安装于或与使用电能的设备相连接的装置； - 通过机械或电气方式操作，并能对作用点位置变化作出响应的设备。 注2：不属于自动控制一部分的手动开关要求，见 IEC 61058-1-1。 本文档适用于： - 自动机电式位移电气控制装置的本体安全； - 自动机电式位移电气控制装置的功能安全； - 与控制装置安全相关的操作参数、操作时间及操作序列； - 具有温度敏感元件的位移式电气控制装置（此时可能需要额外要求）。 温度敏感控制装置的要求见 IEC 60730-2-9。 本文档规定了用于、安装于或与设备相连接的自动位移式电气控制装置的构造、操作及测试要求。 本文档不适用： - 自动电子控制装置； - 控制装置的自动响应值，若该响应值取决于控制装置在设备中的安装方式。 若响应值对保护用户或周围环境具有重要意义，则应采用相应设备标准中规定的值或由制造商确定的值。 注3：关于位移式电气控制装置应用指南的更多信息，见附录 AA。 本部分（2-24）应与 IEC 60730-1 配套使用，其制定基于该标准第六版（2022 年版）。未来可考虑对 IEC 60730-1 的后续版本或修订内容进行适用性评估。 本部分 2-24 对 IEC 60730-1 中相应条款进行补充或修改，使其转化为针对“位移式电气控制装置”的 IEC 标准专用要求。 当本部分 2-24 标明“添加”“修改”或“替换”时，应对 IEC 60730-1 第 1 部分中的相关技术要求、测试规范或说明内容作相应调整。若无需改动，则第 2-24 部分将明确指出相关条款或子条款直接适用。 [外文原描述]： IEC 60730-2-24:2026 EXV contains both the international standard and its extended version (EXV). This extended version of the official IEC Standard is available in English only and provides the user with a comprehensive content of the Standard. IEC 60730-2-24:2026 EXV includes the content of the references made to IEC 60730-1:2022. IEC 60730-2-24:2026 applies to automatic displacement electrical controls - for use in, on, or in association with appliances for household and similar use; NOTE 1 Through this document, the word "control" means "displacement electrical control". EXAMPLE 1 Displacement electrical controls used in electrical pressure cookers with gross volume up to 25 l, with working pressure over 4 kPa and less than 150 kPa. - that are AC or DC powered controls with a rated voltage not exceeding 690 V AC or 600 V DC; - used in, on, or in association with equipment that use electricity; - that are mechanically or electrically operated, responsive to change of position of point of action. NOTE 2 Requirements for manual switches not forming part of an automatic control are covered in IEC 61058‑1‑1. This document applies to - inherent safety of automatic electro-mechanical displacement electrical controls; - functional safety of automatic electro-mechanical displacement electrical controls; - the operating values, operating times, and operating sequences where such are associated with equipment safety; - displacement electrical controls having temperature sensing element(s), in which cases additional requirements can be considered to be necessary. Requirements for temperature sensing controls are included in IEC 60730-2-9. This document specifies the requirements for construction, operation and testing of automatic displacement electrical controls used in, on, or in association with equipment. This document does not - apply to automatic electronic controls; - take into account the response value of an automatic action of a control, if such a response value is dependent upon the method of mounting the control in the equipment. Where a response value is of significant purpose for the protection of the user, or surroundings, the value defined in the appropriate equipment standard or as determined by the manufacturer applies. NOTE 3 For more information about guidance to the application of displacement electrical controls, see Annex AA. This part 2-24 is intended to be used in conjunction with IEC 60730-1. It was established on the basis of the sixth edition of that standard (2022). Consideration may be given to future editions of, or amendments to, IEC 60730‑1. This part 2-24 supplements or modifies the corresponding clauses in IEC 60730-1, so as to convert that publication into the IEC standard: Particular requirements for displacement electrical controls. Where this part 2-24 states "addition", "modification" or "replacement", the relevant require­ment, test specification or explanatory matter in Part 1 should be adapted accordingly. Where no change is necessary, part 2-24 indicates that the relevant clause or subclause applies.
