TESLA TP-0000906 Soiling and Cleaning Behavior - Dirt Resistance of Internal Surfaces

The “TESLA TP-0000906 Soiling and cleaning behavior - Dirt resistance of interior surfaces” standard developed by TESLA, an American company that designs, manufactures and sells electric vehicles, describes a test method to determine the dirt resistance of interior surfaces within the scope of the fouling and cleaning behavior of vehicles.

Dirt resistance is defined as the ability to resist contamination from atmospheric dust and is an important performance of exterior coatings. Cleaning the interior surfaces of the vehicle protects various parts of the vehicle from damage. In general, the dirt resistance of vehicle interior surfaces is an important indicator in terms of preventing damage, fading or discoloration, mold or cracking.

The accumulation of dust (dirt) on interior surfaces is caused by triboelectric static electricity, which is similar to the friction-based static electricity encountered every day. The triboelectric effect is a type of electrification effect by touch, defined as the electrical charge of certain materials as a result of touching and separating each other. Surface friction causes a static electric charge to occur as electrons are exchanged between the surface of the plastic part and another object. The accumulation begins during part production and continues through shipping, installation and finally use. The negatively charged plastic then begins to attract positively charged dust particles. If no precautions are taken, a layer of dust will accumulate on instrument panels, center consoles, doors, pillars and other plastic surfaces in just a few weeks.

Compound antistatic polymers produce particles that repel dust and preserve the clean appearance of the vehicle interior, offering an alternative to laborious cleaning. Material suppliers now therefore offer various types of compound antistatic, dust-repellent plastics.

Interior trim provides the following main benefits that contribute to the longevity and appearance of the vehicle interior:

• Stain resistance: Interior coatings create a barrier that repels liquid spills and stains, preventing them from penetrating and damaging materials.
• Ultraviolet (UV) protection: Coatings protect the vehicle interior from harmful UV rays, preventing materials from fading, cracking and deteriorating.
• Easy maintenance: Coated surfaces are easier to clean and maintain as it is more difficult for dirt and grime to adhere to treated surfaces.
• Improved appearance: A well-maintained interior coated with protective products looks more attractively luxurious.

With the tests applied within the scope of the TESLA TP-0000906 standard, a pristine, comfortable and well-protected car interior is obtained.

Among the numerous testing, measurement, analysis and evaluation studies provided to businesses by our organization, there are also testing services in accordance with the "TESLA TP-0000906 Pollution and cleaning behavior - Dirt resistance of internal surfaces" standard.
