BS EN IEC 63350:2026
This standard BS EN IEC 63350:2026 Household electric appliances — Specification of the properties of a digital system for measuring the performance is classified in these ICS categories:
- 97.040.20 Cooking ranges, working tables, ovens and similar appliances
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).
