This International Standard describes requirements for tooth-like colour representations made of
ceramic materials used to determine the tooth colour in the patient’s mouth or to check the colour of
dental prosthesis, which are referred to as shade guides (colour rings) in this standard.
The coordinates of tooth colours in the colour space (colour coordinates) the specification of which is left
to the manufacturers’ discretion as well as the colour deviations of ceramic and other masses or m...view more

IEC 61966-12-1:2020 is available as IEC 61966-12-1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61966-12-1:2020 defines the colour gamut metadata scheme for video systems and similar applications. The metadata can be associated with wide-gamut video colour content or to a piece of equipment to display the content. When associated with content, the colour gamut metadata defines the...view more

This document specifies the most important requirements of telescopic tripods for surveying instruments and the connection between instrument and tripod. The requirements in this document enable instruments and tripods of different manufacturers to be joined to one another, without prejudicing their performance and their usefulness. This document is applicable to tripods which are used for levels, theodolites, tacheometers, GPS equipment, EDM instruments and in combination with targets, reflecto...view more

ISO 18619 specifies a procedure, including computation, by which a transform between ICC profiles can be adjusted (compensated) to take into account differences between the dark end of the source colour space and the dark end of the destination colour space. This is referred to as black point compensation (BPC). The relative colorimetric encoding of ICC profile transforms already provides a mechanism for such adjustment of the light (white) end of the tone scale.

ISO/TS 23564 describes procedures for evaluating the accuracy of colorimetric rendering intents in ICC profiles.It applies to v4 ICC profiles made according to ISO 15076-1.It does not apply to subjective tests of ICC profiles, such as for perceptual or saturation rendering intents, and it does not apply to high dynamic range colour media or spaces.

ISO/TS 21830 specifies a procedure, including computation, for extending the method described in ISO 18619:2015 to n-colour ICC profiles specifically for the xCLR cases where the colourants are either CMYK plus combinations from the set of red, orange, green, blue and violet or where, for the 3CLR case, the colourants are CMY-like chromatic colourants with widely-spaced hue angles. Other types of colour spaces which are otherwise permitted by 15076-1, such as 2CLR (two-device colourants), are no...view more

IEC 63145-22-20:2020(E) specifies the standard measurement conditions and measuring methods for determining the see-through optical properties and imaging quality of augmented reality (AR) eyewear displays. This includes the transmission characteristics and ambient optical performance of the eyewear displays.
Contact lens type displays are out of the scope of this document.
NOTE The relationship between the scope and other documents (IEC 63145-20-10, IEC 63145-22-10) is shown in Annex A.

This European Standard specifies the requirements for measurement of electrical, photometric, and colorimetric quantities of LED lamps, modules, light engines and luminaires, for operation with AC or DC supply voltages, possibly with associated control gear. Photometric and colorimetric quantities covered in this standard include total luminous flux, luminous efficacy, partial luminous flux, luminous intensity distribution, centre-beam intensities, luminance and luminance distribution, chromatic...view more

IEC 63145-20-20:2019 (E) specifies the standard measurement conditions and measurement methods for determining the image quality of eyewear displays. This document is applicable to non-see-through type (virtual reality “VR” goggle) and see-through type (augmented reality “AR” glasses) eyewear displays using virtual image optics.
Contact-lens type displays and retina direct projection displays are out of the scope of this document.

This document specifies colour-matching functions for use in colorimetry. Two sets of colour-matching
functions are specified.
a) Colour-matching functions for the CIE 1931 standard colorimetric observer.
This set of colour-matching functions is representative of the colour-matching properties of
observers with normal colour vision for visual field sizes of angular subtense from about 1° to
about 4°, for vision at photopic levels of adaptation.
b) Colour-matching functions for the CIE 1964...view more

This document specifies a method of calculating the coordinates of the CIE 1976 L*a*b* colour space,
including correlates of lightness, chroma and hue. It includes two methods for calculating Euclidean
distances in this space to represent the perceived magnitude of colour differences.
This document is applicable to tristimulus values calculated using colour-matching functions of the
CIE 1931 standard colorimetric system or the CIE 1964 standard colorimetric system. This document
can be used...view more

This part of IEC 62129 describes the calibration of optical frequency meters using an optical
frequency comb as an internal reference. It is applicable to instruments measuring the optical
frequency emitted from sources that are typical for the fibre-optic communications industry. It
is assumed that the optical radiation will be coupled to the optical frequency meter by a singlemode
optical fibre. This document is part of the IEC 62129 series on the calibration of
wavelength/optical frequen...view more

This document specifies methods of calculating the tristimulus values of colour stimuli for which
the spectral distributions are provided. These colour stimuli can be produced by self-luminous light
sources or by reflecting or transmitting objects.
This document requires that the colour stimulus function be tabulated at measurement intervals of
5 nm or less in a wavelength range of at least 380 nm to 780 nm. Extrapolation methods are suggested
for cases where the measured wavelength range i...view more

This European Standard defines selection ranks for LED Luminaires, and LEDs including OLEDs for the use in aircraft lighting. The size of these ranks is defined by the use of grades. This European Standard is valid for photopic light levels only.
