家用电气设备 测量性能的数字系统的特性规范（IEC 63350:2026; EN IEC 63350:2026）

[中文适用范围]： IEC 63350:2026 规定了用于创建数字系统的通用要求，该系统旨在测量人眼可察觉的性能特征（如褐变强度和亮度）。本标准明确了该数字系统的计量学要求，并展示了符合性验证程序。该数字系统包含实现测量过程所需的测量仪器、软件和参考材料。客户在指定数字系统时，或供应商在说明所供产品时，均可引用本标准。相关方可同意将本标准作为满足各类活动中计量管理体系要求的输入依据。第一版本文件作废并取代 2022 年发布的 IEC TS 63350。本版相较于 IEC TS 63350 包含以下主要技术变更：a）条款 4.2 修订：允许评估区域内存在可移动物品（例如容器、工装夹具、参考物体），但须采取缓解措施，并对与已知参考实物进行的定期校准进行记录；同时保留“评估区域应尽可能保持恒定”的要求。b）新增支持性文件：条款 5.1 中的注引入了 Fogra 52 色彩配置（收录于 IEC SC 59K 支持性文件网站提供的参考色彩支持文档中），该配置引用了 ISO 12647-7 和 ISO 12647-2 的条件。c）条款 5.3 新增四种色相角大于 130° 的参考色样，用于校准（以实现准确的逐像素色相角测量）；此举不产生新的色样类别。d）条款 6.2 修订：采样位置的计算方式保持不变，但执行流程已优化，以更真实地反映实际测试场景。e）新增输入图像色彩通道数据的报告（7.7）。 [外文原描述]： CORRECTED VERSION 2026-02 IEC 63350:2026 specifies generic requirements for creating a digital system that is used for measuring the characteristics of visually detectable performance, such as browning intensity and lightness. It defines the metrological requirements of this digital system and demonstrates the procedures for compliance. The digital system contains the measuring instrument, the software, and the reference materials necessary to realize the measurement process. References to this document can be made by a customer when specifying the digital system and by the suppliers when specifying products offered. Interested parties can agree to use this document as an input for satisfying measurement management system requirements in any activities. This first edition cancels and replaces IEC TS 63350, published in 2022. This edition includes the following significant technical changes with respect to IEC TS 63350: a) Revision of 4.2: movable items (e.g., containers, jigs, reference objects) can now be present in the assessment area provided that mitigation measures are applied and periodic verification against known reference artefacts is documented; the requirement to keep the assessment area as constant as possible is retained. b) Addition of new supporting document: Note in 5.1 introduces the Fogra 52 profile (included in the reference colour supporting documents from the IEC SC 59K supporting documents web site) which is referencing the conditions ISO 12647-7 and ISO 12647-2. c) Four additional reference shades with hue angles > 130° are introduced in 5.3 for calibration (to enable accurate pixel‑wise hue‑angle measurement). These do not create new shade classes. d) Revision of 6.2: Calculation of sampling positions remains unchanged, but the procedure changes to reflect better the actual test scenario. e) Added reporting of input image colour channel data (7.7). This corrected version of IEC 63350:2026 incorporates the following correction: – Addition of bibliographic reference numbers in the content
