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 materials
used in the manufacture of dental prosthesis do not fall into the scope of this standard.
Resources for visualizing the colours of ceramic and other masses, e.g. mass shade guides and colour
patterns for certain ceramic and other masses, do not fall into the scope of this International Standard.
They can be manufactured from any materials and serve solely to illustrate the colour effect; they do not
serve colour determination inside the mouth.

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 gamut for which the content was created. It can be used by the display for controlled colour reproduction even if the display’s colour gamut is different from that of the content. When associated with a display, the colour gamut metadata defines the display colour gamut. It can be used during content creation to enable improved colour reproduction. The colour gamut metadata can cover associated colour encoding information, which includes all information required for a controlled colour reproduction, when such information is not provided by the colour encoding specification. The colour gamut metadata scheme provides scalable solutions. For example, more flexible solutions will be used for the professional use, while much simpler solutions will be used for consumer use with easier product implementation. This part of IEC 61966 only defines the colour gamut metadata scheme. Vendor-specific solutions for creation and end-use of this metadata are allowed. IEC 61966-12-1:2020 cancels and replaces the first edition published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) ITU-R BT.2020 colour spaces added in Clause 6;
b) ITU-R BT.2100 colour spaces added in Clause 6.

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.

This document specifies a detailed method, based on the spectral transmission data of the materials, comprising the solar protection devices and the glazing, to determine the total solar energy transmittance and other relevant solar-optical data of the combination. If spectral data are not available the methodology can be adapted to use in-tegrated data.
The method is valid for all types of solar protection devices parallel to the glazing such as louvres, or venetian, or roller blinds. The blind may be located internally, externally, or enclosed between the panes of the glazing. Ventilation of the blind is allowed for in each of these positions in determining the solar energy absorbed by the glazing or blind components, for vertical orientation of the glazing.
The blind component materials may be transparent, translucent or opaque, combined with glazing components with known solar transmittance and reflectance and with known emissivity for thermal radiation.
The method is based on a normal incidence of radiation and does not take into account an angular dependence of transmittance or reflectance of the materials. Diffuse irradiation or radiation diffused by solar protection devices is treated as if it were direct. Louvres or venetian blinds are treated as homogenous materials by equivalent solar optical characteristics, which may depend on the angle of the incidence radiation. For situations outside the scope of this document; ISO 15099 covers a wider range of situations.
The document also gives certain normalised situations, additional assumptions and necessary boundary conditions.
No change to the scope is expected. There will be editorial revision (new structure) in the context of Mandate M/480 and maybe minor technical changes due to inconsistency to other standards under Mandate M/480

This European Standard specifies a simplified method based on the thermal transmittance and total solar energy transmittance of the glazing and on the light transmittance and reflectance of the solar protection device to estimate the total solar energy transmittance of a solar protection device combined with glazing.
The method applies to all types of solar protection devices parallel to the glazing such as louvre, venetian or roller blinds. The position of the solar protection device can be interior, exterior or between single panes in a dual glazing system. It is applicable when the total solar energy transmittance of the glazing is between 0,15 and 0,85. Venetian or louvre blinds are assumed to be adjusted so that there is no direct solar penetration. It is assumed that for external solar protection devices and for integrated solar protection devices, the space between the solar protection devices and the glazing is unventilated and for internal solar protection devices this space is ventilated.
The resulting g-values of the simplified method given here are approximate and their deviation from the exact values lie within the range between +0,10 and -0,02. The results generally tend to lie on the safe side for cooling load estimations. The results are not intended to be used for calculating beneficial solar gains or thermal comfort criteria. The simplified method is based on the normal incidence of radiation and does not take into account either the angular dependence of transmittance and the reflectance or the differences of spectral distribution.
This standard can be applied when the solar transmittance and solar reflectance of the solar protection devices are within the following ranges:
0  e,B  0,5 and 0,1  e,B  0,8
For reflectance and transmittance values outside these ranges EN 13363-2 [1] applies.
An allowance can be made for this fact when applying the method. For cases not covered by the method given in this standard more exact calculations based on the optical properties (in general the spectral data) of glass and solar protection device can be carried out in accordance with EN 13363-2 [1].
No change to the scope is expected. There will be editorial revision (new structure) in the context of Mandate M/480 and maybe minor technical changes due to inconsistency to other standards under Mandate M/480

This part of EN 13523 specifies the procedure for determining the difference in the colour of an organic coating on a metallic substrate by visual comparison against a standard using either diffuse natural daylight or artificial daylight in a standard booth.
NOTE 1   Results might differ between natural and artificial daylight.
It might be that two colour specimens will match in daylight but not under another light source. This phenomenon is known as metamerism (see EN 13523-15).
NOTE 2   If metameric match is to be reported in objective terms, spectrophotometric measurements (using CIE Standard Illuminants D65 and A) should be made, in accordance with EN 13523-15.
No statement is made about either the precision or the accuracy of this procedure since the results derived are neither in numerical form nor do they provide a pass/fail evaluation in objective terms. Therefore, this procedure should only be used where the use of colour measuring instruments is not recommendable (evaluation of colour matches, inspection of metallic colours, etc.).
The standardization of such visual comparisons, by light sources, illuminating and viewing geometry and specimen size, provides for improved uniformity of results. This practice is essential for critical colour matching and is highly recommended for colour inspections.

This part of EN 13523 specifies the basic principles and procedure for determining the resistance of an organic coating on a metallic substrate (coil coating) to a combination of fluorescent UV radiation, and water condensation and temperature under controlled conditions.
Due to varied conditions which occur during natural weathering and the extreme nature of accelerated testing, correlation between the two cannot be expected.
Not all organic coatings will perform on an equal basis but a degree of correlation between the same generic type might be observed.

appears to be emitting light as a primary light source or that appears to be specularly reflecting such
light. Only the u′,v′ uniform chromaticity scale diagram defined in 4.1 and the correlates of hue and

It also specifies the method of calculating the coordinates of the u′,v′ uniform chromaticity scale diagram.
ISO/CIE 11664-5:2016 is applicable to tristimulus values calculated using the colour-matching functions of the CIE 1931 standard colorimetric system or the CIE 1964 standard colorimetric system. This part of ISO/CIE 11664 may be used for the specification of colour stimuli perceived as belonging to a reflecting or transmitting object, where a three-dimensional space more uniform than tristimulus space is required. This includes self-luminous displays, like cathode ray tubes, if they are being used to simulate reflecting or transmitting objects and if the stimuli are appropriately normalized. This part of ISO/CIE 11664, as a whole, does not apply to colour stimuli perceived as belonging to an area that appears to be emitting light as a primary light source or that appears to be specularly reflecting such light. Only the u′,v′ uniform chromaticity scale diagram defined in 4.1 and the correlates of hue and saturation defined in 4.3 apply to such colour stimuli.

This International Standard specifies a method for estimating the colour of optically clear,
yellow/brownish coloured liquid products by means of the Gardner colour scale using colour-measuring
instruments. The method uses the Gardner colour scale described in Annex A.
It is applicable to drying oils, varnishes and solutions of fatty acids, polymerized fatty acids, resins, tall
oil, tall oil fatty acids, rosin and related products. The results might be invalid if other products are tested.
The method described provides a more precise way of measuring Gardner colour than a visual sample
comparison using human eyes. It is applicable to products having colours from Gardner 1 to Gardner 18.
The Gardner scale is not applicable to products with colours darker than 18. For products with colours
lighter than Gardner 1 the method specified in ISO 6271 applies.

This International Standard specifies a spectrophotometric method for estimating the colour of clear
liquids in terms of platinum-cobalt units (Pt-Co units). It is applicable to clear liquids having a colour
characteristic similar to those of the platinum-cobalt colour scale specified in Annex A. For products
with colours more intense than the Pt-Co stock solution the method specified in ISO 4630 applies.
The spectrophotometric method provides a more precise way of measuring Pt-Co colour than a visual
sample comparison by human eyes.
NOTE The term “Pt-Co colour” used here is preferred over the terms “Hazen colour” and “APHA colour”.

This Part of EN 13523 defines terms of the procedure for determining the metamerism of a colour match of an organic coating on a metallic substrate.
When two colour specimens have identical spectral reflection curves, they are matching under any illuminant irrespective of its spectral characteristics. This is termed a "spectral match". It is also possible for two colour specimens having different spectral reflection curves to match visually under a given light source but not to match under another light source with different spectral characteristics; such matches are termed "metameric".
One quantitative description of metamerism is the so-called "metamerism index".
The information of the metamerism index is of limited value where E (instrumental colour difference for a given illuminant, see EN 13523-3:2001) is > 0,5. The metamerism index is not suited for determining the absolute colour difference or colour constancy of a given specimen at change of illuminant.
The colour difference under the reference illuminant is to be measured in colour coordinates L*, a* and b* (see EN 13523-3:2001).
Excluded from this method are organic coatings producing fluorescence and/or which are multicoloured, pearlescent or metallic.

EN IEC 61966-12-2 specifies the colour gamut metadata format for video systems intended for use in CE (Consumer Electronics) devices. The metadata specified in this part of IEC 61966 is limited to the gamut description of additive three primary colours type displays whose white and black points have the same chromaticity. It is fundamentally based on the conventional VESA-EDID format. When associated with content, the simple metadata format defines the gamut for which the content was created. It can be used by the display for controlled colour reproduction even if the display’s colour gamut is different from that of the content. When associated with a display, the simple metadata format defines the display colour gamut. It can be used during content creation to enable improved colour reproduction. This standard provides the simplest, but unambiguous solution for typical CE devices that are based on colour gamut information communication.

EN 13523-2 specifies the procedure for determining the gloss of an organic coating on a metallic substrate. Gloss is a characteristic of fundamental importance to the appearance of the coil coated product. The apparatus requires a flat specimen of size greater than the aperture, thus, uneven surfaces cannot be measured. This method is applicable to all pigmented and unpigmented coatings including metallic/pearlescent coatings. However, for textured coatings it is only indicative.
