EN ISO 18314-1:2018

Analytical colorimetry - Part 1: Practical colour measurement (ISO 18314-1:2015)

ISO 18314-1:2015 specifies the method for determining the colour coordinates of a paint film. This method is only applicable to paint films that appear to be uniformly of one colour, i.e. monochromatic, when examined with normal vision. Paint films that do not completely hide a non-transparent substrate represent an opaque system and can be measured by using the procedure in this part of ISO 18314.
Luminescent paint films, transparent paint films, and translucent paint films (for example for display or lamp glass), retroreflecting paint films (for example for traffic signs), and metallic paint films are outside the scope of this part of ISO 18314.

Analyse colorimétrique - Partie 1: Mesurage pratique de la couleur (ISO 18314-1:2015)

La présente partie de l'ISO 18314 spécifie la méthode de détermination des coordonnées colorimétriques d'un feuil de peinture. Cette méthode n'est applicable qu'aux feuils de peinture dont la couleur semble uniforme à l'œil nu, c'est-à-dire aux feuils de peinture monochromatiques. Les feuils de peinture dont le pouvoir couvrant n'est pas suffisant pour masquer complètement un subjectile non transparent constituent un système opaque et peuvent être analysés en utilisant la méthode spécifiée dans la présente partie de l'ISO 18314.
Les feuils de peinture luminescents, transparents et translucides (par exemple, ceux sur un écran ou un verre d'ampoule), les feuils de peinture rétroréfléchissants (par exemple, ceux sur les panneaux de signalisation routière), ainsi que les feuils de peinture métalliques ne sont pas couverts par le domaine d'application de la présente partie de l'ISO 18314.

Analizna kolorometrija - 1. del: Praktično merjenje barve (ISO 18314-1:2015)

ISO 18314-1:2015 določa metodo za določanje barvnih koordinat barvne plasti. Ta metoda se uporablja samo za barvne plasti, ki se zdijo enotno enobarvne, tj. monokromatske, kadar se preučujejo z običajnim vidom. Barvne plasti, ki neprosojne podlage ne prikrivajo povsem, predstavljajo prosojen sistem in jih je mogoče izmeriti z uporabo postopka v tem delu standarda ISO 18314.
Luminescenčne, prosojne in prozorne barvne plasti (na primer za steklo za zaslone ali sijalke), retroreflekcijske barvne plasti (na primer za prometne znake) ter kovinske barvne plasti so zunaj področja uporabe tega dela standarda ISO 18314.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers

Analytical colorimetry —
Part 1:
Practical colour measurement
1 Scope
This part of ISO 18314 specifies the method for determining the colour coordinates of a paint film. This
method is only applicable to paint films that appear to be uniformly of one colour, i.e. monochromatic,
when examined with normal vision. Paint films that do not completely hide a non-transparent substrate
represent an opaque system and can be measured by using the procedure in this part of ISO 18314.
Luminescent paint films, transparent paint films, and translucent paint films (for example for display
or lamp glass), retroreflecting paint films (for example for traffic signs), and metallic paint films are
outside the scope of this part of ISO 18314.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are
indispensable for its application. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any amendments) applies.
ISO 1513, Paints and varnishes — Examination and preparation of test samples
ISO 1514, Paints and varnishes — Standard panels for testing
ISO 2808, Paints and varnishes — Determination of film thickness
ISO 15528, Paints, varnishes and raw materials for paints and varnishes — Sampling
3 Sample preparation
Take a representative sample of the paint to be tested as described in accordance with ISO 15528.
Examine and prepare the sample for testing in accordance with ISO 1513.
Prepare the test panels in accordance with ISO 1514. Apply the coating always in the same way (e.g. by
spraying, brushing, or with application bars), dry or stove and, if necessary, condition the paint film as
directed in the manufacturer’s instructions or as otherwise agreed.
If the paint film is of reversible temperature-dependent colour, the temperature of the test sample should
be maintained at (23 ± 2) °C by appropriate measures (for example by the use of a thermostatically
controlled sample holder). Paint films of irreversible temperature-dependent colour should be
postconditioned, until the colour does not change any more. In the case of paint films that do not
completely hide the substrate, the colour depends on the colour of the substrate and the film thickness,
which should be determined by one of the procedures given in ISO 2808.
The paint film sample shall not be scratched and shall be free from dust and grease (e.g. fingerprints).
For process control of painted articles take representative test samples. The number of samples shall be
agreed upon between the parties.
