Aerospace series - Paints and varnishes - Determination of the effect of thermal exposure

This European Standard specifies the method of test for determining the resistance of paints and varnishes to the effects of heat or cold within the limits of - 50 °C to 200 °C.
The test procedure assesses the resistance of paint coatings, varnishes or related products to changes of gloss, colour, blistering, cracking and/or detachment from the substrate as a result of exposure to elevated or sub ambient temperature.
The procedure is applicable to products intended for use in aerospace applications.

Luft- und Raumfahrt - Beschichtungsstoffe - Thermische Beanspruchung

Diese Norm legt die Verfahren zum Prüfen der Beständigkeit von Beschichtungen gegenüber den Auswirkungen von Hitze oder Kälte von – 50 °C bis 200 °C fest.
Das Prüfverfahren beurteilt die Beständigkeit von Beschichtungen und ähnlichen Produkten hinsichtlich der Veränderungen von Glanz, Farbe, Blasenbildung, Rissbildung und/oder Ablösung vom Untergrund als Ergebnisse der Beanspruchung mit hohen oder niedrigen Umgebungstemperaturen.
Dieses Verfahren ist auf Produkte anwendbar, die für den Einsatz in Luft- und Raumfahrt bestimmt sind.

SIST EN 4160:2011 - Aerospace series - Paints and varnishes - Determination of the effect of thermal exposure

Overview

EN 4160:2011 is a European Standard developed by CEN that specifies a test method to determine the resistance of aerospace paints and varnishes to thermal exposure. This standard focuses on evaluating the effects of heat and cold on coatings within a temperature range of -50 °C to 200 °C. It is particularly designed for materials used in aerospace applications where durability under extreme thermal conditions is critical.

The standard outlines procedures to test changes in gloss, color, blistering, cracking, and detachment of paint or varnish from substrates after exposure to elevated or sub-ambient temperatures. By following this standardized method, manufacturers can ensure their coatings meet stringent aerospace performance requirements.

Key Topics

  • Thermal Resistance Testing
    Measures coating performance after exposure to temperatures between -50 °C and 200 °C.

  • Assessment Criteria
    Includes changes in gloss, color variation, blistering, cracking, and detachment from the substrate.

  • Test Procedure
    Utilizes temperature-controlled chambers to expose coated panels, followed by post-exposure conditioning and examination.

  • Sample Preparation
    Requires representative samples prepared in accordance with related EN ISO standards covering paint thickness, application methods, and curing processes.

  • Evaluation Methods
    Applies internationally recognized testing guidelines such as EN ISO 2813 for gloss measurement and EN ISO 4628 parts for evaluating degradation like blistering and cracking.

  • Documentation and Reporting
    Comprehensive test reports documenting product identification, test conditions, observed results, and any deviations from the method are mandated.

Applications

EN 4160:2011 is essential for aerospace manufacturers and suppliers involved in selecting and qualifying paints and varnishes for aircraft and spacecraft components. Key applications include:

  • Aircraft Exterior Coatings
    Ensuring long-term durability and aesthetic integrity despite exposure to varying atmospheric temperatures.

  • Spacecraft Protective Layers
    Verifying resistance to temperature extremes encountered during launch, orbit, and re-entry phases.

  • Component Quality Control
    Routine testing for quality assurance during production or after modification of coating formulations.

  • Material Research and Development
    Supporting innovation in thermal resistant coatings designed to improve performance or reduce maintenance in aerospace environments.

This standard facilitates interoperability and compliance with aerospace industry requirements, helping manufacturers deliver reliable coatings that withstand harsh thermal conditions.
