Model of information document for type approval of vehicle with respect to the installation of devices for indirect vision.

Communication concerning the approval or refusal or extension or withdrawal of approval or production definitely discontinued of a type of device for indirect vision, pursuant to Regulation No Communication concerning the approval or refusal or extension or withdrawal of approval or production definitely discontinued of a vehicle type with regard to the installation of devices for indirect vision, pursuant to Regulation No This Regulation applies: a to compulsory and optional devices for indirect vision, set out in the table under para graph Devices for indirect vision means devices to observe the traffic area adjacent to the vehicle which cannot be observed by direct vision.

These can be conventional mirrors, camera-monitors or other devices able to present information about the indirect field of vision to the driver. Mirror means any device, excluding devices such as periscopes, intended to give a clear view to the rear, side or front of the vehicle within the fields of vision defined in paragraph Interior mirror means a device as defined in paragraph2.

Exterior mirror means a device as defined in paragraph2. Surveillance mirror means a mirror other than the ones defined in paragraph2. The principal radii of curvature at one point on the reflecting surface ri means the values obtained with the apparatus defined in Annex7, measured on the arc of the reflecting surface passing through the centre of this surface parallel to the segment b, as defined in para graph6.

The radius of curvature at one point on the reflecting surface rp means the arithmetical aver age of the principal radii of curvature ri and ri i. Aspherical mirror means a mirror composed of a spherical and an aspherical part, in which the transition of the reflecting surface from the spherical to the aspherical part has to be marked. The radius of curvature of the constituent parts of the mirror means the radius c of the arc of the circle which most closely approximates to the curved form of the part in question.

Class of mirror means all devices having one or more common characteristics or functions. They are classified as follows:. Class IV: Wide-angle exterior mirror, giving the field of vision defined in paragraph Class V: Close-proximity exterior mirror, giving the field of vision defined in paragraph Camera-monitor device for indirect vision means a device as defined in paragraph2.

Camera means a device that renders an image of the outside world and then converts this image into a signal e. Monitor means a device that converts a signal into images that are rendered into the visual spectrum.

Resolution means the smallest detail that can be discerned with a perceptual system, i. The resolution of the human eye is indicated as visual acuity. Critical perception means the level of perception that the human eye is generally capable of achieving under various conditions. For traffic conditions the limiting value for a critical per ception is eight arc-minutes of visual angle.

Field of vision means the section of the tri-dimensional space which is monitored with the help of a device for indirect vision. This may be limited by the relevant detec tion distance corresponding to the critical object.. Detection distance means the distance measured at ground level from the viewing reference point to the extreme point at which a critical object can just be perceived the limiting value for a critical perception just barely achieved.

Critical field of vision means the area in which a critical object has to be detected by means of a device for indirect vision and that is defined by an angle and one or more detection distances. Viewing reference point means the point linked to the vehicle to which the prescribed field of vision is related. This point is the projection on the ground of the intersection of a vertical plane passing through the drivers ocular points with a plane parallel to the median longitudinal plane of the vehicle situated 20cm outside the vehicle.

Visual spectrum means light with a wavelength within the range of the perceptual limits of the human eyes: nm. The relevancy of a road user is defined by his or her position and potential speed.

More or less in proportion with the speed of the pedestrian-cyclist- moped driver, the dimensions of these road users increase as well.

Considering the speeds, the moped driver would be selected as the criterion for the detection size; for that reason an object with a size of 0,8m shall be used for determining the detection performance. Other devices for indirect vision means devices as defined in paragraph2. Type of device for indirect vision means devices that do not differ on the following essential characteristics:. The application for approval of a type of device for indirect vision shall be submitted by the holder of the trade name or mark or by his duly accredited representative.

Additional speci mens may be called for at the request of the laboratory;. The samples of devices for indirect vision submitted for approval shall bear the trade name or mark of the manufacturer; this marking shall be clearly legible and be indelible. Every device shall possess a space large enough to accommodate the approval mark, which must be legible when the device has been mounted on the vehicle; this space shall be shown on the drawings referred to in Annex1.

If the samples submitted for approval meet the requirements of paragraph6 of this Regulation, approval of the pertinent type of device for indirect vision shall be granted.

An approval number shall be assigned to each type approved. Its first two digits at present 02 shall indicate the series of amendments incorporating the most recent major technical amend ments made to the Regulation at the time of issue of the approval.

The same Contracting Party shall not assign the same number to another type of device for indirect vision. Notice of approval or of refusal or of extension or withdrawal of approval or of production defi nitely discontinued of a type of device for indirect vision pursuant to this Regulation shall be communicated to the Parties to the Agreement which apply this Regulation by means of a form conforming to the model in Annex3 to this Regulation.

There shall be affixed, conspicuously and in the space referred to in paragraph 4. A circle surrounding the letter E followed by the distinguishing number of the country which has granted approval 3 ;.

The additional symbol shall be placed in any convenient position in the vicinity of the circle con taining the letter E. Annex5 to this Regulation gives an example of the arrangement of the aforesaid approval mark and additional symbol. The edge of the reflecting surface must be enclosed in a protective housing holder, etc. If the reflecting surface projects beyond the protective housing, the radius of curva ture c on the edge of the projecting part must be not less than 2,5mm and the reflecting sur face must return into the protective housing under a force of 50N applied to the point of greatest projection, relative to the protective housing, in a horizontal direction, approximately parallel to the longitudinal median plane of the vehicle.

When the mirror is mounted on a plane surface, all parts, irrespective of the adjustment posi tion of the device, including those parts remaining attached to the support after the test pro vided for in paragraph6. Edges of fixing holes or recesses of which the diameter or longest diagonal is less than 12mm are exempt from the radius requirements of paragraph6. The device for the attachment of mirrors to the vehicle must be so designed that a cylinder with a 70mm radius 50mm in the case of an L-categoryvehicle , having as its axis the axis, or one of the axes, of pivot or rotation which ensures deflection of the mirror in the direction of impact concerned, passes through at least part of the surface to which the device is attached.

The parts of exterior mirrors referred to in paragraphs6. In the case of those parts of interior mirrors which are made of a material with a Shore A hard ness of less than 50 and which are mounted on a rigid support, the requirements of para graphs6. Interior rear-view mirrors Class I The dimensions of the reflecting surface must be such that it is possible to inscribe thereon a rectangle one side of which is 40mm and the other a mm in length, where.

Where rear view mirrors are not circular, their dimensions shall enable a 78 mm-diameter circle to be prescribed on their reflecting surface. The reflecting surface of a mirror must be either flat or spherically convex.

Exterior mirrors may be equipped with an additional aspherical part provided that the main mirror fulfils the require ments of the indirect field of vision. The difference between any of the radii of curvature rp1, rp2, and rp3 and r must not exceed 0,15 r.

When r is not less than mm, the value of 0,15 r quoted in paragraphs 6. Aspherical mirrors shall be of sufficient size and shape to provide useful information to the driver.

This normally means a minimum width of 30mm at some point. The value of the normal coefficient of reflection, as determined according to the method described in Annex6, must be not less than 40 per cent. In the case of reflecting surfaces with a changeable degree of reflection, the day position must allow the colours of the signals used for road traffic to be recognized. The value of the normal coefficient of reflection in the night position must be not less than 4 per cent.

The reflecting surface must retain the characteristics laid down in paragraph6. Class VII mirrors with a stem, shall be subjected to the tests described in paragraph6. The test provided for in paragraph6. This derogation also applies to the attachments of mirrors attachment plates, arms, swivel joints, etc.

In such cases, a description specifying that the mirror must be mounted so as to conform to the above-mentioned conditions for the positioning of its attachments on the vehicle must be provided. Where advantage is taken of this derogation, the arm shall be indelibly marked with the. Impact test The test according to this paragraph is not to be carried out for devices integrated in the body work of the vehicle and providing a frontal deflecting area of an angle not more than 45 mea sured in relation to the longitudinal median plane of the vehicle, or devices not protruding more than mm measured beyond the circumscribing bodywork of the vehicle according to Regu lation No The test rig consists of a pendulum capable of swinging about two horizontal axes at right angles to each other, one of which is perpendicular to the plane containing the release trajectory of the pendulum.

The end of the pendulum comprises a hammer formed by a rigid sphere with a diameter of 1mm having a 5mm thick rubber covering of Shore A hardness A device is provided which permits determination of the maximum angle assumed by the arm in the plane of release.

A support firmly fixed to the structure of the pendulum serves to hold the specimens in com pliance with the impact requirements specified in paragraph6. Figure 1 below gives the dimensions in mm of the test rig and the special design specifications:. The centre of percussion of the pendulum coincides with the centre of the sphere, which forms the hammer. It is at a distance l from the axis of oscillation in the release plane, which is equal to1m 5mm.

The relation ship of mo to the total mass m of the pendulum and to the distance d between the centre of grav ity of the pendulum and its axis of rotation is expressed in the equation:. The procedure used to clamp the mirror to the support shall be that recommended by the manu facturer of the device or, where appropriate, by the vehicle manufacturer. Mirrors shall be positioned on the pendulum impact rig in such a way that the axes which are horizontal and vertical when the mirror is installed on a vehicle in accordance with the appli cants mounting instructions are in a similar position; 6.

When a mirror is adjustable with respect to the base, the test position shall be that in which any pivoting device is least likely to operate, within the limits of adjustment provided by the applicant; 6.

When the mirror has a device for adjusting its distance from the base, the device must be set in the position in which the distance between the housing and the base is shortest; 6. When the reflecting surface is mobile in the housing, it shall be so adjusted that the upper cor ner, which is furthest from the vehicle, is in the position of greatest projection relative to the housing.

Except in the case of test 2 for interior mirrors see paragraph6. The longitudinal direction of oscillation of the pendulum shall be parallel to the longitudinal median plane of the vehicle. When, under the conditions governing adjustment laid down in paragraphs 6. The displacement must be no greater than is strictly necessary for the execution of the test; it must be limited in such a way that:.
