préface

OIN (Organisation internationale de normalisation) est une alliance mondiale d'organismes de normalisation nationaux (Comités membres de l'ISO). L'élaboration de normes internationales est généralement réalisée par l'intermédiaire de comités techniques ISO.. Chaque institution membre intéressée par un sujet pour lequel un comité technique a été créé a le droit d'être représentée au sein de ce comité.. Les organisations internationales gouvernementales et non gouvernementales en liaison avec l'ISO sont également impliquées dans ces travaux.. L'ISO travaille en étroite collaboration avec la Commission électrotechnique internationale (CEI) sur toutes les questions de normalisation électrotechnique.

Les projets de normes internationales adoptés par le Comité technique seront distribués aux comités membres pour vote.. La publication en tant que norme internationale nécessite l'approbation d'au moins 75% des comités membres.

La norme internationale ISO 12040 a été développé par le comité technique ISO/TC 130, Graphic Technology.

Annex A to this standard is for reference only.

OIN 12040-1997 Technologie d'impression – Assessment of light resistance of prints and printing inks using filtered xenon arc lamps

introduire
The methods described in this standard for evaluating light resistance using blue wool references are technically consistent with those given in ISO 2835. Cependant, according to the latter, natural light should be used to obtain a valid evaluation of light resistance. This standard describes accelerated test methods by specifying light sources and filters for daylight simulation and by exposing test samples to artificial sunlight.

En outre, the international standard is partially consistent with ISO 105-B02. For more information on equipment and test methods, it is recommended to refer to ISO 105-B02.

1 gamme
This standard specifies a method for assessing the light fastness of prints and printing inks by giving

– General test requirements for printed matter;

— Special testing requirements for inks.

This standard applies to all printing substrates such as paper, board, métal (sheet metal and sheet metal) and plastic film and all printing processes.

2 Références normatives
The following standards contain provisions which, by reference, constitute the provisions of this International Standard. At the time of publication, the version shown is valid. All standards are subject to revision and parties to an agreement based on this international standard are encouraged to investigate the possibility of applying new versions of the following standards. IEC and ISO members maintain a register of international standards currently in force.

ISO 105-A02:1993, Textiles. Tests for colour fastness – Part A02: Greyscale for assessing colour change.

OIN 105-B02:1994, Textiles. Tests for colour fastness – Part B02: Colour fastness to artificial light: xenon arc fading lamp test.

OIN 2834:1981, printing inks. Preparation of standardized prints for the determination of tolerance to physical and chemical agents.

OIN 3664:1975, La photographie – View the lighting conditions of colour transparencies and their reproductions.

OIN 12040-1997 Technologie d'impression – Assessment of light resistance of prints and printing inks using filtered xenon arc lamps

3 Définition
For the purposes of this standard, the following definitions apply.

3.1 Light resistance of printed matter to filtered xenon arc light

Printed matter is resistant to the effects of fixed light sources (filtered xenon arcs) and is not directly affected by the weather.

3.2 Light fastness of printing ink

To assess the resistance of standard printed matter according to the instructions for printed matter in this international Standard.
