Adhesives - Determination of the colour and/or colour changes of adhesive coats under the influence of light

This European standard is applicable to solvent-based, dispersion, hot-melt and reactive adhesives, their basic constituents, and related products the coating of which are coloured and/or subject to a change of colour by light. It describes a method of measuring the colour of an adhesive coat and the magnitudeof a change of colour under the influence of light.

Klebstoffe - Bestimmung der Farbe und/oder der Farbänderung von Klebaufstrichen unter Lichteinwirkung

Diese Norm gilt für Lösungsmittel-, Dispersions-, Schmelz- und Reaktionsklebstoffe, für ihre Bestandteile sowie für verwandte Produkte, deren   Klebaufstriche farbig sind und/oder bei Lichteinwirkung ihre Farbe ändern. Sie beschreibt eine Methode zur Messung der Farbe von Klebaufstrichen sowie zur Messung des Grades ihrer Farbänderung bei Lichteinwirkung.

Adhésifs - Détermination de la couleur et/ou des changements de couleur des revêtements adhésifs sous l'influence de la lumière

La présente norme est applicable aux adhésifs à base de solvants, à dispersion, thermofusibles et réactifs, à leurs constituants de base et aux produits connexes dont les revêtements sont colorés et/ou sujets à un changement de couleur dû à la lumière. Elle décrit une méthode permettant de mesurer la couleur d'un revêtement adhésif et l'importance d'un changement de couleur sous l'influence de la lumière.

Overview

EN 1244:1998 (CEN) specifies a standardized method for assessing the colour and colour change of adhesive coats under the influence of light. The standard applies to a wide range of adhesive types - including solvent‑based, dispersion, hot‑melt and reactive adhesives - as well as their basic constituents and related coloured coatings that may undergo light‑induced colour change. EN 1244 describes how to measure the initial colour of an adhesive coat and how to quantify the magnitude of any change when the coating is exposed to light.

Key topics and requirements

• Scope and applicability: Covers solvent‑based, dispersion, hot‑melt and reactive adhesives and related coloured coatings that may change colour on light exposure.
• Measurement objective: Defines a method to determine the colour of an adhesive coat and to quantify the degree of colour change after light exposure.
• Reproducibility and comparability: Emphasizes consistent sample preparation, controlled exposure conditions and standardized measurement procedures so results are comparable between laboratories.
• Reporting: Requires clear reporting of test conditions and results so users can interpret colour stability and compare products.
• Quality focus: Designed to support quality control, product development and acceptance criteria for adhesive manufacturers and users.

(Note: EN 1244 provides the method framework; specific instrument types, exposure regimes or numerical thresholds are defined in the standard text.)

Applications and who uses it

EN 1244 is practical for organizations that need to evaluate or control colour stability of adhesive coatings:

• Adhesive manufacturers - for product development, formulation selection and quality assurance of coloured adhesives.
• Coatings formulators and raw‑material suppliers - to assess pigment, dye and additive effects on lightfastness.
• Independent testing laboratories - to provide comparable, certified colour‑change testing services.
• OEMs and specifiers - to set procurement or acceptance criteria where adhesive appearance and colour stability are important (e.g., visible joints, laminates, packaging).
• Regulatory and standards committees - to reference a harmonized method for light‑induced colour change of adhesive coatings.

Related standards

• EN 1244 complements other CEN standards on adhesive performance and durability. Users often apply EN 1244 alongside broader ageing, mechanical or chemical resistance tests to build a complete performance profile.
