DAF KEUR 00822-114 Coating Materials - Determination of Water Resistance

The “DAF KEUR 00822-114 Coating Materials - Determination of Water Resistance” standard, developed as part of the official approval or certification process for parts, materials, or processes used in trucks manufactured by DAF, a Dutch truck manufacturer, is a specific technical testing standard used by DAF trucks and related testing laboratories to evaluate material behavior underwater. This standard is part of the DAF KEUR 00822 series of standards for color fastness, dimensional stability, durability, and environmental resistance of interior coating materials, helping to ensure that vehicle components meet stringent performance and durability criteria. This standard is particularly important for interior materials and coatings used in vehicle cabins.

Truck cabs are frequently exposed to water and moisture sources: driver perspiration, rain ingress (e.g., through open doors or poor seals), spilled drinks, wet clothing in adverse weather conditions, condensation in cold climates, and regular wet cleaning. Materials with poor water resistance may exhibit the following problems:

• Color bleeding or staining, transferring to adjacent surfaces, clothing or skin.
• Paint transfer while wet (critical for multicolored or printed fabrics)
• Color fastness decreases upon contact with sweat or water droplets.
• Changes such as staining, darkening, or dye migration on the surface

This testing method ensures that interior materials (seat covers, door panels, headliners) are resistant to these effects, preventing visible defects, customer complaints, and warranty issues, and maintaining a clean and professional appearance for the truck's 10-15 year service life.

This standard is closely aligned with the following international standards for established textile color fastness for waterproofing:

• ISO 105-E01 Color fastness to water
• Color fastness to seawater, if adapted to ISO 105-E02.
• ISO 105-X07 Color fastness to water staining.
• ISO 105-E04 Sweat fastness elements for water/sweat effects.

In short, the DAF KEUR 00822-114 standard defines a method for evaluating how coating materials react when exposed to water, assessing their resistance and durability under wet conditions. This standard also includes:

• Resistance of textile materials to color bleeding (i.e., color transfer).
• Water and sweat fasting
• Resistance to water droplet impacts.

In practice, the DAF KEUR 00822-114 standard examines whether materials retain their appearance, color, and physical integrity when exposed to water, sweat, or moisture. These are conditions frequently encountered in vehicle cabins during daily use.

This standard belongs to a family of test methods for material performance, particularly for coating materials. Other related tests in the DAF KEUR 00822 category include:

• DAF KEUR 00822-107 Lightfastness - Color stability under light exposure.
• DAF KEUR 00822-108 Friction resistance - Resistance to friction.
• DAF KEUR 00822-113 Shrinkage due to moisture.
• DAF KEUR 00822-114 Water resistance and durability
• DFA KEUR 00822-115 Resistance to aging
• DFA KEUR 00822-116 Wear and tear resistance
• DFA KEUR 00822-120 Condensation behavior
• DFA KEUR 00822-122 Sensitivity to electrostatic charges

This demonstrates how DAF systematically evaluates its materials against the many stresses they may encounter during service.

When determining water resistance, the following steps are generally followed:

• Samples are conditioned before testing.
• Samples are brought into contact with water or aqueous solutions (e.g., immersion, dripping, or contact with wet cloth).
• Controlled conditions are applied (e.g., room temperature or high temperature, with or without pressure).
• After exposure, the sample is evaluated in the following aspects:
• Color change or bleeding
• Surface damage
• Dimensional changes
• Other signs of deterioration
• Color change in the sample and staining/bleeding onto adjacent multi-fiber or reference fabrics are evaluated using gray scales (grades 1-5, 5 = no change/no staining).

Precise parameters such as temperature, duration, and type of water exposure are defined in the detailed test method within the standard. This method targets flat surface materials such as woven/knitted fabrics, coated textiles, and artificial leather used in truck interiors.

The exact pass/fail criteria (e.g., minimum grayscale ratings) are detailed within the standard.

This standard is vital to ensure that truck interior materials can withstand real-world moisture exposure without compromising aesthetics, hygiene, or durability. These are important factors for customer satisfaction and the long-term value of the vehicles.

Heavy-duty vehicles, such as those produced by DAF, operate in a wide variety of climates and environmental conditions. Materials in the driver's cab, especially seat fabrics, upholstery, headliners, and other coverings, must withstand moisture without deterioration. Key considerations include:

• Aesthetic stability: Fabrics should not bleed color or fade when wet.
• Dimensional integrity: Materials must not deform, bend, or lose their shape due to water.
• Durability: Exposure to water or sweat should not lead to premature wear.

DAF specifies waterproofing tests to ensure that the materials used inside their trucks can withstand realistic liquid exposure without compromising comfort or appearance.

In short, the DAF KEUR 00822-114 standard is a proprietary DAF truck test standard for the waterproofness of cladding materials. It evaluates how materials react to exposure to water, including resistance to water droplets, sweat, and water-induced color bleeding. This standard helps ensure that interior materials maintain their appearance and performance over time.
