DAF KEUR 00822-108 Coating Materials - Determination of Color Fastness to Friction

The “DAF KEUR 00822-108 Coating materials – Determination of color fastness to friction” standard, developed as part of the formal approval or certification process for parts, materials, or processes used in trucks manufactured by DAF, a Dutch truck manufacturer, describes a test method for evaluating how well coating materials (e.g., textiles, leather, synthetic fabrics, upholstery, or other interior trim materials in truck cabs) resist color transfer or fading when exposed to friction or abrasion. This standard is part of the broader KEUR 00822 series of standards focusing on color fastness, aging, abrasion, and related properties of materials.

In heavy-duty vehicles like DAF trucks, interior materials are constantly exposed to contact from drivers, passengers, clothing, tools, and cleaning. Poor abrasive resistance can lead to visible wear, staining of clothing, or deterioration of aesthetics over time. This testing helps suppliers and manufacturers ensure that materials meet DAF's durability and customer satisfaction quality requirements.

This standard is derived from, or closely aligned with, “ISO 105-X12 Textiles - Color fastness tests - Part X12: Color fastness to friction”, an internationally used method for textiles and similar materials.

In general, this test follows these steps:

• Sample preparation: Small samples are cut from the coating material (usually in both machine and cross directions). The top colored surface is cleaned and prepared.
• Types of friction conditions: The fabric used to rub against the sample is treated differently depending on the test:
• Dry friction fabric under conditioned ambient conditions.
• Wet rubbing cloth soaked in distilled water.
• Soapy or solvent-based conditions simulate more aggressive abrasion or exposure.
• Friction motion test: A weighted friction needle covered with a standard friction cloth is moved back and forth across the material surface (e.g., 10 back and forth movements over a fixed length). This simulates repeated contact, such as clothing rubbing against upholstery.
• Evaluation: After the rubbing process, both the test sample and the rubbed cloth are evaluated using a gray scale for color change or transfer. This is a standardized comparison tool that helps to rate how much color shift or transfer has occurred. Typically, a rating of 1-5 is given (where 5 = excellent, no transfer, 1 = severe transfer).

This method applies to flat upholstery materials in truck interiors, such as seat fabrics, door panels, headliners, and other textile or coated surfaces.

This standard is included in the supplier qualification lists for DAF truck components.

In short, the DAF KEUR 00822-108 standard is a company-specific test standard used to evaluate the color fastness (often referred to as abrasion fastness) of materials used in vehicle interiors. This specification addresses upholstery materials such as textiles, foam, and similar surfaces found in seats, upholstery panels, and other interior components.

Color fastness to friction is the ability of a material's surface color to resist fading or transfer when rubbed under specified conditions. Practically, it helps answer questions such as:

• Will the fabric color bleed or transfer to another surface when repeatedly touched?
• Will the colors remain stable under normal wear and tear from clothing, bags, or seat movement?

This feature is crucial in automotive interiors because insufficient abrasion resistance can lead to visible color transfer, streaking, or dulling, reducing the perceived quality and durability of upholstery and trim.

In the real world, interior materials are subjected to a wide variety of contact and friction scenarios:

• People getting in and out of the seats.
• Bags or tools pressing against upholstery surfaces.
• Everyday use, contact with wet or dry clothing.

If the colors transfer easily or fade when rubbed, it could be due to:

• It can cause interior spaces to look worn prematurely.
• It can leave visible marks or stains that are difficult to remove.
• It reduces customer satisfaction regarding perceived quality.

The DAF KEUR 00822-108 standard helps ensure that materials selected by suppliers meet the specific performance expectations of DAF vehicles by defining a repeatable, standardized test.

The DAF KEUR 00822-108 standard is part of a broader set of DAF coating material tests. Some related standards in this series include:

• DAF KEUR 00822-107 Color fastness to light.
• DAF KEUR 00822-108 Color fastness to friction.
• DAF KEUR 00822-115 Resistance to aging
• DAF KEUR 00822-116 Wear and tear resistance
• DAF KEUR 00822-120 Condensation behavior
• DAF KEUR 00822-122 Electrostatic charge sensitivity

Together, these factors help ensure not only mechanical durability but also the visual and functional longevity of interior surfaces.

In conclusion, the DAF KEUR 00822-108 standard is a specific standard used to evaluate the abrasion resistance (color fastness to friction) of coating materials. This standard defines how materials should be tested to ensure that colors do not transfer or deteriorate under friction in real-world usage conditions, which helps maintain the interior appearance and customer satisfaction over time. The fundamental aim and methods of this standard closely align with globally accepted textile friction fastness practices, adapted to automotive needs.
