Fingerprint Test for BMW PR 506 Interior Surfaces

Developed by BMW, a leading German multinational company in the automotive sector, the “BMW PR 506 Fingerprint Test for Interior Surfaces” standard describes a specific test method developed to evaluate the resistance of vehicle interior surfaces to fingertip abrasion or simulated human touch/fingerprint marks. This standard involves simulating repeated contact from human fingers over time, such as touching buttons, upholstery, touchscreens, gear selectors, door handles, or other interior components. This method assesses how well materials and coatings on plastic, painted, or functional surfaces withstand:

• Wear and tear caused by skin oils, sweat, and mechanical friction.
• Visible changes such as decreased brightness, discoloration, scratching, or fingerprint residue accumulation.
• Long-term durability in real-world use where drivers and passengers frequently interact with surfaces.

This standard is part of BMW’s broader requirements for interior material quality and durability, ensuring vehicles maintain a superior feel and look even after years of use. Advanced laboratories and suppliers utilize specialized equipment, such as the Abrex abrasion tester, to accurately perform this test. This device simulates fingertip/hand contact under controlled conditions (load, speed, cycles, and sometimes artificial skin oils or soil/dirt simulators).

The purpose of this standard is to verify that interior trim components (especially frequently touched areas within the cabin) maintain their aesthetic and functional quality. It is generally referenced in conjunction with the following standards:

For painted plastic parts on the exterior, interior, and engine compartment (single coat and multi-coat painting).

• BMW GS 97045 (resistance to skin lotions or creams).
• BMW PR 556 (cream resistance for thermoplastics).
• DIN EN 60068-2-70 or IEC 68-2-70 (environmental test for abrasion).
• VW TL 226, DBL 7384 (similar tests from other original equipment manufacturers).

Devices like Abrex, used in tests, simulate dynamic finger movement with precise control over force, cycles (up to millions), and the environment (e.g., artificial fingerprints or dirt).

This method applies to painted plastics, functional coatings (e.g., gear levers or logos), hard coatings, and other interior materials.

BMW places great emphasis on interior quality, particularly in luxury and premium models. Poor resistance to fingerprints or wear can lead to visible deterioration, customer complaints, and a decrease in perceived value. The BMW PR 506 standard helps suppliers and BMW ensure that materials meet stringent durability specifications before production approval.

This test is a material testing specification used entirely in quality assurance and supplier verification. For those working on material certification, supplier testing, or automotive interior development, this standard is a key requirement for BMW for high-contact surfaces.

The BMW PR 506 standard is a critical standard of quality and durability for BMW because it directly addresses one of the most common real-world complaints about premium vehicle interiors: visible wear, stains, and deterioration from everyday human contact.

This standard is considered important for the following reasons:

• It maintains its perceived superior quality over time: High-contact surfaces (touchscreens, iDrive controls, gear selectors, door handles, steering wheel controls, piano black finish, buttons and decorative elements) are constantly used. Without strong resistance to fingerprints, skin oils and micro-abrasion, these surfaces quickly show signs of wear and tear.
• Changes in brightness (blurring or dullness)
• Persistent stains or fingerprint residue
• Micro-scratches and damages
• Discoloration or oily appearance

This undermines the sense of luxury and can make even a well-maintained car look neglected, negatively impacting its resale value and brand image.

• Customer satisfaction and reduced complaints: Modern interiors in vehicles (especially glossy black plastics or high-gloss surfaces) are often criticized for being fingerprint magnets. Poor performance in this area leads to dissatisfaction, negative reviews, and warranty claims. BMW uses this standard to ensure suppliers offer materials/coatings resistant to these problems, thus minimizing after-sales issues and maintaining customer loyalty.
• Competitive advantage in the premium segment: Luxury car buyers expect durability commensurate with the price. Exceeding this standard helps BMW ensure its interiors stand out in terms of long-term quality, especially in models with large touchscreens.
• Supplier quality control and production approval: To approve parts for use in BMW vehicles, suppliers must demonstrate compliance with this standard during development and verification. This prevents costly redesigns, production delays, or field failures. Testing uses precise simulations (e.g., controlled cycles, force and artificial skin lubricants with Abrex testing equipment) to predict years of real-world use in a short laboratory time.

In conclusion, the BMW PR 506 standard is not merely a technical procedure; it is a crucial tool BMW uses to deliver on its promise of superior driving experience.
