家用电磁烹饪器具 第2部分：灶台 性能测量方法

[中文适用范围]： IEC 60350-2:2025 RLV包含了官方的IEC国际标准及其修订版（Redline版本）。Redline版本仅以英文提供，便于用户快速比较当前IEC标准与前一版之间的所有变更。IEC 60350-2:2025规定了测量家用灶具性能的方法。本文件所涵盖的灶具可以是嵌入式或设计为放置在工作台面上的类型。灶具可以是烹饪炉的一部分，并可以配备集成式油烟抽取装置（即下抽式系统）。本文件定义了用户关心的灶具主要性能特性，并规定了测量这些特性的方法。本文件未对性能进行分类或评级。本文件中规定的一些测试由于在不同实验室之间的结果可能不同，因此不被视为可重复的测试，仅用于比较测试。本文件不涉及安全要求（IEC 60335-2-6和IEC 60335-2-9）。本文件也适用于具有类似功能的便携式电器。本版第三版取消并替代了2017年发布的第二版及2021年的修正案1。本版为技术修订版。与前一版相比，本版包括以下重大技术变更：a) 第3章对便携式灶具、下抽式系统灶具和低功率模式的新定义进行了修订；b) 第5章进行了修订，增加了对添加水量的公差要求和尺寸测量的要求；c) 删除第6.4条“加热板的固体等级”；d) 修订第7章，以改进平滑平均值的应用；e) 修订表1和表3，以修正遗漏的公差；f) 第9章中将Ry替换为L*，并引用IEC TS 63350；g) 由于IEC TS 63350已涵盖相关内容，删除第9.1.6条中关于数字评估的要求；h) 修订第12章关于低功率模式的功率测量；i) 删除第13章“灶具的溢出容量”；j) 增加附录G“低功率模式测量”；k) 删除附录D“色阶图”，因为色阶图在IEC TS 63350中已规定；l) 删除附录E“数据和计算表”，因为计算表已被网站上的支持文件替代；m) 更新了附录F“供应商地址”，删除原第F.6、F.7和F.8条，并在D.4中新增了一个可能的供应商。 [外文原描述]： IEC 60350-2:2025 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 60350-2:2025 defines methods for measuring the performance of electric hobs for household use. Appliances covered by this document can be built-in or designed to be placed on a work surface. The hob can be part of a cooking range and it can have an integrated cooking fume extractor, i.e. a hob with down-draft system . This document defines the main performance characteristics of hobs which are of interest to the user and specifies methods for measuring these characteristics. This document does not specify a classification or ranking for performance. Some of the tests which are specified in this document are not considered to be reproducible since the results can vary between laboratories. They are therefore intended for comparative testing purposes only. This document does not deal with safety requirements (IEC 60335-2-6 and IEC 60335-2-9). This document is also applicable for portable appliances with similar functionality. This third edition cancels and replaces the second edition published in 2017 and Amendment 1:2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) new definitions for portable hob, hob with down-draft system and low power modes are amended in Clause 3; b) revision of Clause 5: Tolerance for water amount added, requirements for dimension measurement added; c) removal of 6.4 Level of solid hotplates; d) revision of Clause 7 in order to improve the application of the smoothing average; e) revision of Table 1 and Table 3 in order to amend missing tolerances: f) Ry replaced by L* in Clause 9 and reference to IEC TS 63350; g) requirements for digital assessment in 9.1.6 removed as they are covered in IEC TS 63350; h) revision of Clause 12 Power measurement of low power modes; i) removal of Clause 13 Spillage capacity of hobs; j) Annex G Low-power mode measurements added; k) removal of Annex D 'Shade chart' as the shade charts are specified in IEC TS 63350; l) removal of Annex E 'Data and calculation sheet' as the calculation sheet is substituted by a supporting document located on the IEC web site; m) update of former Annex F 'Addresses of suppliers' by removal of former Clause F.6, F.7 and F.8 and by adding a further possible supplier in new D.4
