IEC 62977-2-7:2024 specifies standard measuring conditions and measurement methods for determining the optical characteristics of tiled displays which consist of multiple display modules in order to form one screen. These methods apply to emissive and transmissive direct view flat displays that render real 2D images with all modules lying in the same plane. The methods are applicable in environments where the measuring conditions can be controlled, such as laboratory and production testing.
NOTE The measurement results are not specific values for the products. They can vary according to the measurement method and light measuring device (LMD) used in the calibration.

IEC TS 60825-19:2024 specifies the velocity-dependent closest points of human access (VCPHA) for the classification of moving platform laser products when considering the movement of the platform with respect to a stationary frame of reference. This presupposes that the inherent kinetic hazard of the moving platform creates a zone in which persons would not be reasonably expected to be located. Additionally, it takes neighbouring moving platforms into account by defining stationary and moving apertures. This document is applicable to all laser products whose laser apertures are on a moving platform.
Laser products are sometimes used on moving platforms. Currently the standard IEC 60825-1:2014 considers only a stationary aperture; it does not address the situations where the emitting aperture is mounted on a platform, such as a vehicle, that can be in motion. Failure to consider the effects of the motion of the platform can result in overly restrictive assessment of the hazard.
Although accounting for a platform’s movement during the assessment of a laser product’s classification can lead to less restrictive measurement conditions, it is important not to overlook that there can be apertures, even on other moving platforms, moving at a relative speed of zero or close to zero with respect to the moving platform laser product being classified.

This Standard provides the optical radiation safety requirements for ultraviolet lamp products, including UV LED products. This standard provides requirements for: - optical radiation safety assessment and ultraviolet-product risk groups; - user information for safety measures; - appropriate labelling of ultraviolet lamp products This standard addresses those lamps and lamp products where the ultraviolet emission serves the primary purpose of the product and where more than half of the optical radiation emitted between 180 nm - 3 000 nm is in the spectral region 180 nm - 400 nm. If more than half of the optical radiation emitted between 180 nm - 3 000 nm is outside of the spectral region 180 nm - 400 nm, then the base standard IEC 62471-1 should be used. This standard covers medical diagnostic devices/products that emit primarily UV radiation. Because photobiological effects from UV radiation are based on the total accumulated exposure (dose) received, this standard relies on the concept of ‘Time-weighted Average’ exposures where the assessment distance for determining the RG is chosen based on realistic exposure distances and exposure durations. In other words, it is not expected that people will be exposed at very close distances, e.g. 20 - 30 cm, for extended periods of time. This standard is needed to provide assessment distances and specific guidance that are application-specific and realistic rather than the more general values in IEC 62471 where the specific application is unknown and time-weighted average exposures are not application-specific. This Standard does not provide requirements for: - lamps which primarily emit visible and/or infrared radiant energy - lamp products used for general lighting or infrared illumination or heating, which are treated in separate standards. - fluorescent ultraviolet lamps for tanning (covered by IEC 60335-2-27 and IEC 61228). - medical treatment devices/products (see IEC 60601-2-57), but covers UV medical diagnostic products.

IEC 62977-3-5:2023 specifies standard evaluation methods for determining the colour capabilities of electronic display modules and systems with respect to colour accuracy, colour gamut volume, and their intersection with a reference colour space. Also included is evaluation with respect to the chromaticity gamut area. These methods apply to emissive and transmissive direct view displays that render real 2D images on a flat panel or on a curved panel with a local radius of curvature larger than 1 500 mm. This document evaluates the optical characteristics of these displays under darkroom conditions. This document applies to the testing of display performance in response to standard analogue or digital input signals that are not absolute luminance encoded. The input signal is relative RGB without metadata information that codes for real luminance, colour space or colour coordinates. These methods are limited to input signals with typical opto-electronic transfer functions (OETFs) such as defined in IEC 61966‑2‑1, Recommendation ITU-R BT.601 [18][1], Recommendation ITU-R BT.709, and Recommendation ITU-R BT.2020. The tests in this document are not suitable for use with HDR input signals.
This document contains attached files in the form of Microsoft Excel spreadsheet and App installer. These files are intended to be used as a complement and do not form an integral part of the standard.

This document specifies a method, which is a relatively quick and simple method with minimum equipment, for determining the polarization status and, whenever possible, the degree of polarization of the beam from a continuous wave (cw) laser. It can also be applied to repetitively pulsed lasers, if their electric field vector orientation does not change from pulse to pulse.
This document also specifies the method for determining the direction of the electric-field vector oscillation in the case of (completely or partially) linearly polarized laser beams. It is assumed that the laser radiation is quasimonochromatic and sufficiently stable for the purpose of the measurement. This document is applicable to radiation that has uniform polarization over its cross-sectional area.
The knowledge of the polarization status can be very important for some applications of lasers with a high divergence angle, for instance when the beam of such a laser shall be coupled with polarization dependent devices (e.g. polarization maintaining fibres). This document is applicable not only for a narrow and almost collimated laser beam but also for highly divergent beams as well as for beams with large apertures.

IEC 62629-62-11:2022 specifies the standard measuring conditions and measurement methods for determining the optical properties of the image created by 3D display devices and virtual-image optics such as head-up displays. The virtual image refers to an image in which the 3D visual information is superimposed with the outside world. Eye-wear type displays are however beyond the scope of this document.
NOTE The meaning of a virtual image in optics is in general an image formed when the outgoing rays from a point on an object always diverge. With regard to display application, a virtual image can be interpreted according to a real viewing case. When an image is viewed, even though there is no physical display (monitor, TV, screen), in front of a person's eyes, it is called virtual image.

IEC TR 60825-3:2022 gives guidance on the planning and design, set-up and conduct of laser displays and shows that make use of high power lasers emitting output between 380 nm and 780 nm.
This document is a code of practice for the design, installation, operation and evaluation of the safety of laser light shows and displays, and the equipment employed in their production. This document is also intended for persons who modify laser display installations or equipment.
The laser power needed to produce visually effective theatrical or artistic displays in large spaces such as theatres, arenas, or architectural sites is great enough to pose a severe accidental exposure hazard, even when personal exposure is very brief. For this reason, IEC TR 60825-14 states that only laser products that are Class 1, Class 2 or visible-beam Class 3R should be used for demonstration, display or entertainment purposes in unsupervised areas. Only under carefully controlled conditions and under the control of a trained experienced operator can laser products of higher classes be used for visual entertainment.
This document expands upon the principles considered in IEC TR 60825-14, providing specific technical guidance appropriate for the safe use of laser products used for the purposes of visual entertainment.
