DAF KEUR 00822-116 Coating Materials - Determination of Wear Resistance

The “DAF KEUR 00822-116 Coating materials - Determination of wear 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, evaluates how well materials resist wear and tear caused by environmental factors such as heat, light, oxygen, and humidity by simulating long-term use in the interior or exterior of the truck. They ensure long-term durability under real-world conditions such as wear, environmental exposure, and chemical contact.

The DAF KEUR 00822-116 standard is part of a broader set of KEUR standards relating to coating materials. Some of the relevant standards are:

• DAF KEUR 00821-020 Dimensional stability after thermal aging.
• DAF KEUR 00821-024 Resistance to fungal growth.
• 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 resistance (abrasion resistance)
• DAF KEUR 00822-120 Condensation behavior
• DAF KEUR 00824-402 Scratch resistance
• DAF KEUR 00824-840 Condensation moisture test

These standards are referenced by independent testing laboratories when suppliers qualify parts for DAF trucks.

The DAF KEUR 00822-116 standard specifies the test method used to determine the abrasion resistance (wear resistance) of cladding materials, textiles, upholstery, and similar interior surfaces in DAF truck cabs. This test method typically utilizes a Taber abrasion device, a commonly used rotary abrasion test. In this setup, a test specimen is subjected to controlled friction by abrasive wheels under a specified load. The number of cycles, weight loss, visual changes, or transfer to underlying layers are evaluated.

The aim of this method is to simulate long-term mechanical wear caused by passenger contact, cleaning, or friction in a truck cab environment. This ensures that the materials maintain their appearance, integrity, and functionality throughout the vehicle's service life.

The precise parameters (cycle count, load, abrasive type, evaluation criteria, e.g., visual grading, mass loss limits, or color change) are included in the standard.

DAF prioritizes high quality and durability, in compliance with broader automotive standards such as the supplier quality requirements guideline. KEUR tests are part of the material approval processes for internal components. Failure to meet these requirements may prevent the use of materials in DAF vehicles.

This standard helps ensure that DAF truck interiors withstand heavy commercial use and maintain a professional look for drivers for many years and kilometers.

In short, this standard tests and measures the wear resistance of coating materials. These materials are typically surfaces that are subjected to friction and wear during use. This standard uses the Taber wear method, a widely used laboratory technique. In this method, a sample is systematically abraded under controlled conditions to examine how it withstands wear over many friction cycles.

Essentially, the DAF KEUR 00822-116 standard specifies how to prepare, conduct, and evaluate abrasion tests on materials that must remain durable under repeated use, such as interior upholstery, seat fabrics, protective coatings, or exterior components exposed to friction.

This standard is considered necessary for automotive manufacturers such as DAF for the following reasons:

• Consistency: Ensures that each batch of material meets the same performance criteria before being approved for use in production.
• Quality assurance: By applying standardized tests, DAF can compare suppliers and components against predetermined durability requirements.
• Customer satisfaction: Vehicles manufactured with materials that have passed wear tests tend to have longer-lasting interior and exterior surfaces, which increases overall reliability.
• Supplier communication: The DAF KEUR framework provides suppliers with clear guidelines regarding the expected performance levels of the materials they deliver.

This standard is necessary for the following reasons:

• Prevents color transfer in actual use: Truck interiors are constantly exposed to friction:
• The driver entering and exiting the cabin
• Clothes rubbing against the seats
• Hands touching the steering wheel, panels, or armrests.
• Transporting loads or tools

Without sufficient friction resistance:

• Dark-colored materials can stain light-colored clothing.
• The materials in the response may change color.
• Surfaces may appear prematurely worn.

This standard ensures that materials do not release color or transfer paint under dry or wet friction conditions.

• Provides long-term visibility: Commercial trucks typically operate 8-12 hours a day, in varying humidity and temperature conditions, and for many years. Even minor color irregularities can quickly become visible. This standard ensures:
• Stable appearance over time
• Reducing fading caused by mechanical wear.
• Homogeneous color protection between production batches.

This protects the vehicle's resale value and brand perception.

• Supplier quality consistency is checked: DAF works with multiple material suppliers. A defined testing method:
• It sets a measurable performance threshold.
• It establishes clear pass/fail criteria.
• It ensures reproducibility between laboratories.
• Reduces disagreements about material performance.

Without such a standard, quality can vary significantly between suppliers or production batches.

• It reduces warranty and customer complaints: Color transfer or premature color fading can lead to:
• Warranty claims
• Internal component replacements
• Negative customer feedback

DAF reduces costly field problems by qualifying materials before production.

In conclusion, the DAF KEUR 00822-116 standard is an original equipment manufacturer (OEM) test standard used by DAF to measure the wear resistance of coating materials through a controlled wear test. By ensuring that the materials used in trucks meet high durability and performance standards, it contributes to better vehicle quality and longer service life.
