    Mirror Replacement Systems 
    Prequalified for ISO 16505

    Walk into homologation with confidence. Our iQ-Lab puts your Camera Monitor System through the full ISO 16505 program before the official type-approval test, so there are no surprises when it counts.

    Overview

    Every vehicle on the road carries mirrors that are there by law. UN Regulation No. 46 defines the fields of view a driver must be able to see and sets the requirements for the devices that provide them, the indirect-vision classes I to VI. For decades, that meant glass.

    Camera Monitor Systems (CMS) change the picture. A camera on the bodywork captures the prescribed field of view and a monitor inside the cabin presents it to the driver, enabling lower drag, wider and more flexible fields of view, and digital features such as automatic dimming or trailer-aware framing. But the moment a CMS replaces a mandatory mirror, it inherits that mirror's legal status: it becomes a safety-relevant system that has to meet ISO 16505 to be type-approved under UN R46.

    Type approval is pass or fail. Booking the official homologation test before your system is truly ready is the expensive way to find a problem, a marginal contrast ratio, a resolution that drops at the edges, a glare artifact in the low-sun case, because a failure means redesign, a new test slot, and lost time-to-market. That is exactly the risk the iQ-Lab is built to remove.

    Be sure before it counts: iQ-Lab prequalification

    The iQ-Lab runs your CMS through the same image-quality and performance measurements the homologation test is based on, field of view, magnification, resolution, distortion, OECF, color, luminance and contrast across all five lighting conditions, glare artifacts, and timin, and tells you exactly where your system stands against ISO 16505. You see every marginal parameter early, while there is still room to iterate, and you arrive at type approval with the data to back you up.

    Know. Fix. Approve.

    Know where you stand.

    A standard-driven measurement of every ISO 16505 parameter, reported clearly, pass, fail, or borderline, so nothing is left to chance.

    Fix it while it's cheap.

    Catch and resolve issues in development, before a failed homologation forces a redesign and a second test slot.

    Approach approval with confidence.

    Independent, reproducible results that correlate with the official test, so you book homologation only when you're genuinely ready.

    Note

    The iQ-Lab provides prequalification and development testing. The official type-approval (homologation) test is carried out by your designated technical service or type-approval authority, we make sure that when you get there, there are no surprises.

    What we Measure in Prequalification

    The iQ-Lab evaluates the camera–monitor chain exactly as the driver experiences it, the same parameters the homologation test will check.

    Field of View, Magnification & Resolution

    §We verify that the CMS shows the complete legally prescribed field of view, large enough and sharp enough to be useful. ISO 16505 distinguishes an average from a minimum magnification factor and ties both to the angular resolution the camera–monitor chain actually delivers, because the limiting element of the pair is what the driver ends up seeing.

    Sharpness & Geometric Distortion

    Sharpness is measured as MTF50(1:1) from the spatial frequency response (SFR) of slanted edges, with a direct limit-resolution check (MTF10) on a hyperbolic chart to expose any over-sharpening from image processing. Wide-angle distortion is quantified point by point against an ideal grid, which also confirms that magnification holds across the whole frame.

    Tonal & Color Reproduction

    The opto-electronic conversion function (OECF) describes how scene luminance maps to displayed signal, the system's tonal behavior and the basis for its noise performance. Color is measured on the chart and again as reproduced on the monitor, then compared in the CIE 1976 uniform color space so that color error is expressed in perceptually meaningful terms.

    Luminance, Contrast & Glare

    This is where CMS testing gets demanding. ISO 16505 prescribes five lighting conditions, direct sunlight on the monitor, bright diffuse daylight, night, and two low-sun cases that drive a high-intensity glare source into the camera, and checks contrast, smear, blooming, and lens flare in each. We also assess monitor isotropy and timing (frame rate, image formation time.

    International Standards relevant to Mirror Replacement Systems

    UN Regulation No. 46

    The UNECE regulation on devices for indirect vision and their installation. It defines the mandatory fields of view and the indirect-vision classes (I–VI), and sets the legal framework a CMS must satisfy to replace a mirror at type approval.

    ISO 16505

    Road vehicles, Ergonomic and performance aspects of Camera Monitor Systems. The standard that turns the UN R46 requirements into minimum safety, ergonomic, and performance criteria with defined test procedures for classes I to IV, the basis of our prequalification program.

    ISO 12233

    Photography, Electronic still picture imaging, Resolution and spatial frequency responses. The method ISO 16505 references for SFR-based resolution and sharpness measurement of the camera–monitor chain.

    Prefer to Test In-House?

    If you run your own lab, we supply the exact charts and software the standard calls for, the same equipment the iQ-Lab uses.

    ISO 16505 Chart Bundle

    The five test charts the standard calls for, in one solution: TE197 (OECF, 12-step circular gray scale), TE287 (distortion & magnification, 10 × 20 chessboard), TE288 (resolution via slanted edges), TE289 (color reproduction, circular pattern), and TE290 (resolution / focus line chart). Available in several sizes and customizable to individual requirements.
