IEC TR 62629-1-3:2026, which is Technical Report, is intended to gather technical information of depth perception by human and determination of the position of 3D object on the non-physical screen.
Clause 4 and Clause 5 describe the human depth perception and its threshold. This information will be helpful in designing 3D displays of the non-physical screen type such as the possible depth difference of 3D objects. In the measurement of the display, understanding the response and limitation of the user is useful. Clause 4 and 5 provide such information in determining the 3D object on the non-physical screen.
It is not the intention of this document to set the requirement of the measurement system in determining the position of 3D object on the non-physical screen.

IEC TS 60825-13:2026 provides manufacturers, test houses, safety personnel, and others with practical guidance on methods to perform radiometric measurements or analyses to establish the emission level of laser energy or power in accordance with IEC 60825-1:2014. The measurement procedures described in this document are guidance for classification of laser products in accordance with IEC 60825‑1:2014. It is possible that other procedures are better or more appropriate.
Information is provided for calculating accessible emission limits (AELs) and maximum permissible exposures (MPEs), since some parameters used in calculating the limits are dependent upon other measured quantities.
This document applies to lasers, including extended sources and laser arrays. The procedures described in this document for extended source viewing conditions can yield more conservative results than when using more rigorous methods.

IEC 61496-3:2025 specifies additional requirements for the design, construction and testing of non‑contact electro-sensitive protective equipment (ESPE) designed specifically to detect persons or parts of persons as part of a safety-related system, employing active opto-electronic protective devices responsive to diffuse reflection (AOPDDRs) for the sensing function. Special attention is directed to requirements which ensure that an appropriate safety-related performance is achieved. An ESPE can include optional safety-related functions, the requirements for which are given both in Annex A of this document and in Annex A of IEC 61496‑1:2020.
NOTE "Non-contact" means that physical contact is not required for sensing.
This document does not specify the dimensions or configurations of the detection zone and its disposition in relation to hazardous parts for any particular application, nor what constitutes a hazardous state of any machine. It is restricted to the functioning of the ESPE and how it interfaces with the machine.
AOPDDRs are devices that have either
- one or more detection zone(s) specified in two dimensions (AOPDDR-2D), or
- one or more detection zone(s) specified in three dimensions (AOPDDR-3D)
wherein radiation in the near infrared range is emitted by an emitting element(s). When the emitted radiation impinges on an object (for example, a person or part of a person), a portion of the emitted radiation is reflected to a receiving element(s) by diffuse reflection. This reflection is used to determine the position of the object.
Opto-electronic devices that perform only a single one-dimensional spot-like distance measurement, for example, optical proximity switches, are not covered by this document.
This document is limited to ESPE that do not require human intervention for detection. It is limited to ESPE that detect objects entering into or being present in a detection zone(s).
This document does not address those aspects required for complex classification or differentiation of the object detected.
This document does not address requirements and tests for outdoor application.
Excluded from this document are AOPDDRs employing radiation with the peak of wavelength outside the range 820 nm to 1 100 nm, and those employing radiation other than that generated by the AOPDDR itself. For sensing devices that employ radiation of wavelengths outside this range, this document can be used as a guide. This document is relevant for AOPDDRs having a minimum detectable object size in the range from 30 mm to 200 mm.
This document can be relevant to applications other than those for the protection of persons, for example, for the protection of machinery or products from mechanical damage. In those applications, different requirements can be appropriate, for example when the materials that are recognized by the sensing function have different properties from those of persons and their clothing.
This document does not deal with electromagnetic compatibility (EMC) emission requirements.
This fourth edition cancels and replaces the third edition published in 2018. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) some requirement clauses and test procedures have been adapted or removed because they have been consolidated in IEC 61496-1:2020 (e.g. 5.4.6.2 Light sources and Clause A.9);
b) change of the minimum probability of detection and fault detection requirements for Type 2 AOPDDR;

IEC 62341-6-7:2024 specifies the standard measuring conditions and measuring methods for determining the optical characteristics of an OLED display with under-screen camera; other under-screen features, such as under-screen fingerprint or under-screen time of flight (TOF) can also be applied. This document applies to OLED displays such as mobile phone, monitor and TV with under-screen features.
NOTE Under-screen feature will want the display to be partially transparent and partially non-transparent, and this can be achieved only by certain types of display technology, for example OLED. This document mainly focuses on OLED display with under-screen feature.
