The edge of the reflecting surface shall be enclosed in a protective housing (holder, etc.) which, on its perimeter, shall have a value ‘c’ greater than or equal to 2,5 mm at all points and in all directions. If the reflecting surface projects beyond the protective housing, the radius of curvature ‘c’ on the edge of the projecting part shall be not less than 2,5 mm and the reflecting surface shall return into the protective housing under a force of 50 N 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.

In cases, where the edge of the reflecting surface projects beyond the protective housing, this requirement shall apply to the edge of the projecting part.

6.1.1.3.   When the mirror is mounted on a plane surface, all parts, irrespective of the adjustment position of the device, including those parts remaining attached to the support after the test provided for in paragraph 6.1.3.2 below, which are in potential, static contact with a sphere either 165 mm in diameter in the case of an interior mirror or 100 mm in diameter in the case of an exterior mirror, shall have a radius of curvature ‘c’ of not less than 2,5 mm.

The test according to this paragraph is not to be carried out for devices integrated in the bodywork of the vehicle and providing a frontal deflecting area of an angle not more than 45° measured in relation to the longitudinal median plane of the vehicle, or devices not protruding more than 100 mm measured beyond the circumscribing bodywork of the vehicle according to Regulation No 26.

6.1.3.2.1.   Description of the test rig

6.1.3.2.1.1.   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 165 ± 1 mm having a 5 mm thick rubber covering of Shore A hardness 50.

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 compliance with the impact requirements specified in paragraph 6.1.3.2.2.6 below.

Figure 1 below gives the dimensions (in mm) of the test rig and the special design specifications:

Figure 1

Figure 1

6.1.3.2.1.2.   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 to 1 m ± 5 mm. The reduced mass of the pendulum is mo = 6,8 ± 0,05 kilograms. The relationship of mo to the total mass m of the pendulum and to the distance d between the centre of gravity of the pendulum and its axis of rotation is expressed in the equation:

6.1.3.2.2.   Description of the test

6.1.3.2.2.1.   The procedure used to clamp the mirror to the support shall be that recommended by the manufacturer of the device or, where appropriate, by the vehicle manufacturer.

6.1.3.2.2.2.   Positioning of the mirror for the test:

6.1.3.2.2.2.1.   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 applicant’s mounting instructions are in a similar position;

6.1.3.2.2.2.2.   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;

6.1.3.2.2.2.3.   When the mirror has a device for adjusting its distance from the base, the device shall be set in the position in which the distance between the housing and the base is shortest;

6.1.3.2.2.2.4.   When the reflecting surface is mobile in the housing, it shall be so adjusted that the upper corner, which is furthest from the vehicle, is in the position of greatest projection relative to the housing.

6.1.3.2.2.3.   Except in the case of test 2 for interior mirrors (see paragraph 6.1.3.2.2.6.1 below), when the pendulum is in a vertical position the horizontal and longitudinal vertical planes passing through the centre of the hammer shall pass through the centre of the reflecting surface as defined in paragraph 2.1.1.11 of this Regulation The longitudinal direction of oscillation of the pendulum shall be parallel to the longitudinal median plane of the vehicle.

6.1.3.2.2.4.   When, under the conditions governing adjustment laid down in paragraphs 6.1.3.2.2.1 and 6.1.3.2.2.2 above parts of the mirror limit the return of the hammer, the point of impact shall be displaced in a direction perpendicular to the axis of rotation or pivoting in question.

The displacement shall be no greater than is strictly necessary for the execution of the test; it shall be limited in such a way that:

| (a) | Either the sphere delimiting the hammer remains at least tangential to the cylinder as defined in paragraph 6.1.1.6; |
| --- | --- |

(a)

Either the sphere delimiting the hammer remains at least tangential to the cylinder as defined in paragraph 6.1.1.6;

| (b) | Or the point of contact with the hammer is located at least 10 mm from the periphery of the reflecting surface. |
| --- | --- |

(b)

Or the point of contact with the hammer is located at least 10 mm from the periphery of the reflecting surface.

6.1.3.2.2.5.   The test consists in allowing the hammer to fall from a height corresponding to a pendulum angle of 60° from the vertical so that the hammer strikes the mirror at the moment when the pendulum reaches the vertical position.

6.1.3.2.2.6.   The mirrors are subjected to impact under the following different conditions:

6.1.3.2.2.6.1.   Interior mirrors

6.1.3.3.   Results of the tests

6.1.3.3.1.   In the tests described in paragraph 6.1.3.2 above, the pendulum shall continue to swing after impact in such a way that the projection of the position assumed by the arm on the plane of release makes an angle of at least 20° with the vertical. The accuracy of measurement of the angle shall be within ± 1°.

6.1.3.3.1.1.   This requirement is not applicable to mirrors stuck to the windscreen, in respect of which the requirement stipulated in paragraph 6.1.3.3.2 shall apply after the test.

6.1.3.3.1.2.   The required angle to the vertical is reduced from 20° to 10° for all Class II and Class IV rear-view mirrors and for Class III rear-view mirrors which are attached to the same mounting as Class IV mirrors.

6.1.3.3.2.   Should the mounting of the mirror break during the tests described in paragraph 6.1.3.2 above for mirrors stuck to the windscreen, the part remaining shall not project beyond the base by more than 10 mm and the configuration remaining after the test shall satisfy the conditions laid down in paragraph 6.1.1.3 of this Regulation.

15.2.4.6.   Front mirror (Class VI)

15.2.4.6.1.   The field of vision shall be such that the driver can see at least a flat horizontal portion of the road, which is bounded by:

| (a) | A transverse vertical plane through the outermost point of the front of the vehicle; |
| --- | --- |

(a)

A transverse vertical plane through the outermost point of the front of the vehicle;

| (b) | A transverse vertical plane 2 000 mm in front of the plane defined in (a); |
| --- | --- |

(b)

A transverse vertical plane 2 000 mm in front of the plane defined in (a);

| (c) | A longitudinal vertical plane parallel to the longitudinal vertical median plane going through the outermost side of the vehicle at the driver’s side; and |
| --- | --- |

(c)

A longitudinal vertical plane parallel to the longitudinal vertical median plane going through the outermost side of the vehicle at the driver’s side; and

| (d) | A longitudinal vertical plane parallel to the longitudinal vertical median plane 2 000 mm outside the outermost side of the vehicle opposite to the driver’s side. |
| --- | --- |

(d)

A longitudinal vertical plane parallel to the longitudinal vertical median plane 2 000 mm outside the outermost side of the vehicle opposite to the driver’s side.

The front of this field of vision opposite to the driver’s side may be rounded off with a radius of 2 000 mm (see Figure 9).

For the defined field of vision, see also paragraph 15.2.4.9.2 below.

The provisions for front mirrors are compulsory for forward controlled (as defined in paragraph 12.5 of this Regulation) vehicles of categories N2 > 7,5 t and N3.

15.2.4.6.2.   However, if the driver can see, taking into account the obstructions by the A-pillars, a straight line 300 mm in front of the vehicle at a height of 1 200 mm above the road surface and which is situated between a longitudinal vertical plane parallel to the longitudinal vertical median plane going through the outermost side of the vehicle at the driver’s side and a longitudinal vertical plane parallel to the longitudinal vertical median plane 900 mm outside the outermost side of the vehicle opposite to the driver’s side, a front mirror of Class VI is not mandatory.

15.2.4.6.3.   For the purpose of paragraphs 15.2.4.6.1 and 15.2.4.6.2 above parts permanently attached to the vehicle that are situated both above the driver’s eye points and in front of the transverse vertical plane passing through the foremost surface of the vehicle’s front bumper shall not be taken into account when defining the front of the vehicle.

15.2.4.7.   L-category mirror (Class VII).

15.2.4.7.1.   Exterior rear-view mirror on the driver’s side

The field of vision shall be such that the driver can see at least a 2,50 m wide, flat, horizontal portion of the road, which is bounded by a plane parallel to the median longitudinal vertical plane and passing through the outermost point of the vehicle on the driver’s side of the vehicle and extends from 10 m behind the driver’s ocular points to the horizon (see Figure 10).

15.2.4.7.2.   Exterior rear-view mirror on the passenger’s side

The field of vision shall be such that the driver can see at least a 4 m wide flat, horizontal portion of the road which is bounded by a plane parallel to the median longitudinal vertical plane passing through the outermost point of the vehicle on the passenger’s side and which extends from 20 m behind the driver’s ocular points to the horizon (see Figure 10).

15.2.4.8.   In the case of mirrors consisting of several reflecting surfaces which are either of different curvature or make an angle with each other, at least one of the reflecting surfaces shall provide the field of vision and have the dimensions (paragraph 6.1.2.1.2.2 of this Regulation) specified for the class to which they belong.

15.2.4.9.   Obstructions

15.2.4.9.1.   Interior rear-view mirror (Class I)

The field of vision may be reduced by the presence of devices such as sun visors, windscreen wipers, heating elements and stop lamp of category S3, provided that all these devices together do not obscure more than 15 per cent of the prescribed field of vision. Headrests or framework or bodywork such as window columns of rear split doors, rear window frame shall be excluded from the calculation. This requirement shall be tested by projection on to a vertical plane at right angles to the longitudinal centreplane of the vehicle. The degree of obstruction shall be measured with the sun visors folded back.

15.2.4.9.2.   Exterior mirrors (Classes II, III, IV, V, VI and VII)

In the fields of vision specified above, obstruction due to the bodywork and its components, such as other cab mirrors, door handles, outline marker lights, direction indicators and front and rear bumpers, as well as reflective-surface cleaning components, shall not be taken into account if they are responsible for a total obstruction of less than 10 per cent of the specified field of vision. In the case of a vehicle designed and constructed for special purposes where, due to its special features, it is not possible to meet this requirement, the obstruction of the required field of vision of a Class VI mirror caused by the special features may be more than 10 per cent but not more than necessary for its special function.

15.2.4.10.   Test procedure

The field of vision shall be determined by placing powerful light sources at the ocular points and examining the light reflected on the vertical monitoring screen. Other equivalent methods may be used.

15.3.   Devices for indirect vision other than mirrors

15.3.1.   A device for indirect vision shall give such performances that a critical object can be observed by the driver over the entire required field of vision, taking into account the critical perception according the procedure of Annex 10.

Alternatively, the determination of the displayed object size shall be performed according to Annex 11.

15.3.2.   Obstruction of the driver’s direct view caused by the installation of a device for indirect vision shall be restricted to a minimum.

15.3.3.   (Reserved)

15.3.4.   Installation requirements for the monitor

The viewing direction of the monitor shall roughly be the same direction as the one for the main mirror.

15.3.5.   Vehicles may be equipped with additional devices for indirect vision.

15.3.6.   The provisions of this Regulation do not apply to the surveillance camera-monitor-recording devices defined in paragraph 2.1.2.13 of this Regulation. Exterior surveillance cameras either shall be mounted at least 2 m above the ground when the vehicle is under a load corresponding to its maximum technical permissible mass, or, if their lower edge is less than 2 m from the ground, shall not project more than 50 mm beyond the overall width of the vehicle measured without this device and have a radii of curvature of not less than 2,5 mm.

ANNEX 5

ARRANGEMENT OF APPROVAL MARK OF A DEVICE FOR INDIRECT VISION

(See paragraph 5.4 of the Regulation)

a = 12 mm min.

The above approval mark affixed to a device for indirect vision indicates that the mirror is a rear view mirror, of Class II, which has been approved in the Netherlands (E 4) pursuant to Regulation No 46 and under approval number 042439. The first two digits of the approval number indicate that Regulation No 46 already included the 04 series of amendments when the approval was granted.

Note: The approval number and the additional symbol shall be placed close to the circle and either above or below the ‘E’ or to the left or right of that letter. The digits of the approval number shall be on the same side of the ‘E’ and point in the same direction. The additional symbol shall be directly opposite the approval number. The use of Roman numerals as approval numbers shall be avoided so as to prevent any confusion with other symbols.

TEST METHOD FOR DETERMINING REFLECTIVITY

1.   DEFINITIONS

1.1.   CIE standard illuminate A (1): Colorimetric illuminate, respecting the full radiator at T68 = 2 855,6 K.

1.1.2.   CIE standard source A (1): Gas-filled tungsten filament lamp operating at a correlated colour temperature of T68 = 2 855,6 K.

1.1.3.   CIE 1931 standard colorimetric observer (1): Receptor of radiation whose colorimetric characteristics correspond to the spectral tristimulus values
  Formula
  ,
  Formula
  ,
  Formula
  (see table).

1.1.4.   CIE spectral tristimulus values (1): Tristimulus values of the spectral components of an equi energy spectrum in the CIE (XYZ) system.

1.1.5.   Photopic vision (1): Vision by the normal eye when it is adapted to levels of luminance of at least several cd/m2.

2.   APPARATUS

2.1.   General

The apparatus shall consist of a light source, a holder for the test sample, a receiver unit with a photodetector and an indicating meter (see Figure 1), and means of eliminating the effects of extraneous light.

The receiver may incorporate a light-integrating sphere to facilitate measuring the reflectance of non-flat (convex) mirrors (see Figure 2).

2.2.   Spectral characteristics of light source and receiver

The light source shall consist of a CIE standard source A and associated optics to provide a near-collimated light beam. A voltage stabiliser is recommended in order to maintain a fixed lamp voltage during instrument operation.

The receiver shall have a photodetector with a spectral response proportional to the photopic luminosity function of the CIE (1931) standard colorimetric observer (see table). Any other combination of illuminate-filter-receptor giving the overall equivalent of CIE standard illuminate A and photopic vision may be used. When an integrating sphere is used in the receiver, the interior surface of the sphere shall be coated with a matt (diffusive) spectrally non-selective white coating.

2.3.   Geometrical conditions

The angle of the incident beam (θ) should preferably be 0,44 ± 0,09 rad (25 ± 5°) from the perpendicular to the test surface and shall not exceed the upper limit of the tolerance (i.e. 0,53 rad or 30°). The axis of the receptor shall make an angle (θ) with this perpendicular equal to that of the incident beam (see Figure 1). The incident beam upon arrival at the test surface shall have a diameter of not less than 13 mm (0,5 inch). The reflected beam shall not be wider than the sensitive area of the photodetector, shall not cover less than 50 per cent of such area, and as nearly as possible shall cover the same area segment as used during instrument calibration.

When an integrating sphere is used in the receiver section, the sphere shall have a minimum diameter of 127 mm (5 inch). The sample and incident beam apertures in the sphere wall shall be of such a size as to admit the entire incident and reflected light beams. The photodetector shall be so located as not to receive direct light from either the incident or the reflected beam.

2.4.   Electrical characteristics of the photodetector-indicator unit

The photodetector output as read on the indicating meter shall be a linear function of the light intensity of the photosensitive area. Means (electrical and/or optical) shall be provided to facilitate zeroing and calibration adjustments. Such means shall not affect the linearity or the spectral characteristics of the instrument. The accuracy of the receptor indicator unit shall be within ± 2 per cent of full scale, or ± 10 per cent of the magnitude of the reading, whichever is the smaller.

2.5.   Sample holder

The mechanism shall be capable of locating the test sample so that the axes of the source arm and receptor intersect at the reflecting surface. The reflecting surface may lie within or at either face of the mirror sample, depending on whether it is a first surface, second surface or prismatic ‘flip’ type mirror.

3.   PROCEDURE

3.1.   Direct calibration method

In the direct calibration method, air is used as the reference standard. This method is applicable for those instruments, which are so constructed as to permit calibration at the 100 per cent point by swinging the receiver to a position directly on the axis of the light source (see Figure 1).

It may be desired in some cases (such as when measuring low-reflectivity surfaces) to use an intermediate calibration point (between 0 and 100 per cent on the scale) with this method. In these cases, a neutral density filter of known transmittance shall be inserted in the optical path, and the calibration control shall then be adjusted until the meter reads the percentage transmission of the neutral density filter. This filter shall be removed before reflectivity measurements are performed.

3.2.   Indirect calibration method

The indirect calibration method is applicable in the case of instruments with fixed source and receiver geometry. A properly calibrated and maintained reflectance standard is required. This reference standard should preferably be a flat mirror with a reflectance value as near as possible to that of the test samples.

3.3.   Flat mirror measurement

The reflectance of flat mirror samples can be measured on instruments employing either the direct or the indirect calibration method. The reflectance value is read directly from the indicating meter.

3.4.   Non-flat (convex) mirror measurement

Measurement of the reflectance of non-flat (convex) mirrors requires the use of instruments which incorporate an integrating sphere in the receiver unit (see Figure 2). If the instrument-indicating meter indicates ne divisions with a standard mirror of E per cent reflectance, then, with a mirror of unknown reflectance, nx divisions will correspond to a reflectance of X per cent, in accordance with the formula:

ANNEX 7

PROCEDURE FOR DETERMINING THE RADIUS OF CURVATURE ‘r’ OF THE REFLECTING SURFACE OF A MIRROR

1.   MEASUREMENT

1.1.   Equipment

A ‘spherometer’ similar to the one described in Figure 1 of this annex having the indicated distances between the tracing pin of the dial gauge and the fixed legs of the bar is used.

1.2.   Measuring points

1.2.1.   The principal radii of curvature shall be measured at three points situated as close as possible to positions at one-third, one-half and two-thirds of the distance along the arc of the reflecting surface passing through the centre of this surface and parallel to segment b, or of the arc passing through the centre of the reflecting surface which is perpendicular to it if this arc is the longer.

1.2.2.   Where, owing to the size of the reflecting surface, it is impossible to obtain measurements in the directions defined in paragraph 2.1.1.6 of this Regulation, the Technical Services responsible for the tests may take measurements at the said point in two perpendicular directions as close as possible to those prescribed above.

2.   CALCULATION OF THE RADIUS OF CURVATURE ‘r’

‘r’ expressed in mm is calculated from the formula:

Formula

Where:

| rp1 | = | the radius of curvature at the first measuring point, |
| --- | --- | --- |
| rp2 | = | the radius of curvature at the second measuring point, |
| rp3 | = | the radius of curvature at the third measuring point. |

ANNEX 10

CALCULATION OF THE DETECTION DISTANCE

1.   CAMERA MONITOR DEVICE FOR INDIRECT VISION

1.1.   Determination of the smallest discernable detail

The smallest discernable detail of the naked eye shall be defined according to standard ophthalmologic tests like the Landolt C test or the Triangle Orientation Discrimination (TOD) test. The smallest discernable detail at the centre of the viewing system can be determined using the Landolt C test or the TOD test. In the rest of the viewing area the smallest discernable detail may be estimated from the centrally determined smallest discernable detail and the local image deformation. For instance, in the case of a digital camera the smallest discernable detail at a given pixel location (in the monitor) scales inversely with the solid angle of the pixel.

1.1.1.   Landolt-C test

In the Landolt-C test, test symbols are judged by the subject under test. In accordance with this test the smallest discernable detail is defined as the visual angle of the gap size of the Landolt C symbol at threshold size and is expressed in arcmin. The threshold size corresponds to the size at which the subject judges the orientation correctly in 75 per cent of the trials. The smallest discernable detail is determined in a test involving a human observer. A test chart containing test symbols is placed in front of the camera and the observer judges the orientation of test symbols from the monitor. From the threshold gap size of the Landolt C test symbol d (m) and the distance between the test pattern and the camera D (m) the smallest discernable detail ωc (arcmin) is calculated as follows:

Formula

1.1.2.   TOD test

The Landolt C test can be used to determine the smallest discernable detail of the camera-monitor system. However, for sensor systems it is more suitable to use the TOD (Triangle Orientation Discrimination) method which is similar to the Landolt C method, but involves equilateral triangular test patterns. The Triangle Orientation Discrimination method is described in detail by Bijl & Valeton (1999), who provide practical guidelines on how to perform a TOD measurement. In the method, triangular test patterns (see Figure 1) are viewed through the viewing system under test. Each triangle can have one out of four possible orientations (apex up, left, right or down) and the observer indicates/guesses for each triangle its orientation. When this procedure is repeated for many (randomly oriented) triangles of different sizes the fraction of correct responses can be plotted (see Figure 2), and increases with test pattern size. The threshold is defined as the point at which the fraction correct crosses the 0,75 level and can be obtained by fitting a smooth function through the data (see Bijl & Valeton, 1999). Critical perception is reached when the critical object diameter equals two times the width of the triangle at threshold size. The smallest discernable detail (ωc) is equal to 0,25 times the width of the triangle at threshold size. This means that, from the threshold triangle width w (in m) and the distance between test pattern and the camera D (in m) the smallest discernable detail ωc (in arcmin) is calculated as follows:

Formula

1.2.   Determination of the critical viewing distance of the monitor

For a monitor having certain dimensions and properties, the distance to the monitor can be calculated within which the detection distance is dependent only on the performances of the camera. The critical viewing distance rmcrit is defined as the distance at which the smallest discernable detail displayed on the monitor spans 1 arcmin measured from the eye (the acuity threshold of a standard observer).

Formula

Where:

| rmcrit | : | critical viewing distance of the monitor (m) |
| --- | --- | --- |
| δ | : | size of the smallest discernable detail on the monitor (m) |

rmcrit

:

critical viewing distance of the monitor (m)

δ

:

size of the smallest discernable detail on the monitor (m)

1.3.   Determination of the detection distance

1.3.1.   Maximum detection distance within the critical viewing distance where, due to the installation, the distance eye-monitor is less than the critical viewing distance, the maximum attainable detection distance is defined as:

Formula

Where:

| rdclose | : | detection distance (m) |
| --- | --- | --- |
| D0 | : | diameter of the critical object (m) according to paragraph 2.1.2.6 of this Regulation; for the calculation of rdclose for class V and VI devices, a representative value of 0,30 m shall be used |
| f | : | threshold increasing factor, which is equal to 8 |
| ωc | : | smallest discernable detail (arcmin) |

rdclose

:

detection distance (m)

D0

ωc

:

smallest discernable detail (arcmin)

1.3.2.   Detection distance greater than the critical viewing distance. Where, due to the installation, the distance eye-monitor is more than the critical viewing distance, the maximum obtainable detection distance is defined as:

Formula
  (m)

Where:

| rdfar | : | detection distance for distances larger than the critical viewing distance (m) |
| --- | --- | --- |
| rdclose | : | detection distance for distances smaller than the critical viewing distance (m) |
| rm | : | viewing distance, i.e. distance between eye and monitor (m) |
| rmcrit | : | critical viewing distance (m) |

rdfar

:

detection distance for distances larger than the critical viewing distance (m)

rdclose

:

detection distance for distances smaller than the critical viewing distance (m)

rm

:

viewing distance, i.e. distance between eye and monitor (m)

rmcrit

:

critical viewing distance (m)

2.   SECONDARY FUNCTIONAL REQUIREMENTS

Based on the installation conditions, a determination shall be made to discover whether the entire device can still satisfy the functional requirements listed in paragraph 6.2.2 of this Regulation, especially the glare correction, the maximum and the minimum luminance of the monitor. It shall also be determined the degree to which the glare correction will be addressed and the angle at which sunlight can strike a monitor and these shall be compared to the corresponding measuring results from the system measurements. This can be either based on a CAD-generated model, a determination of the angles of light for the device when mounted on the relevant vehicle, or by carrying out relevant measurements on the relevant vehicle as described in paragraph 6.2.2.2 of this Regulation.

ANNEX 11

DETERMINATION OF THE DISPLAYED OBJECT SIZE

1.   CAMERA MONITOR DEVICE FOR INDIRECT VISION

1.1.   General

Determination of the displayed object size considers the possible appearance of smear. The impact on the monitors image and consequence is the occultation of the field of view and therefore of the object. The following differentiation is made:

1.4.   Data supplied by the instructions for use

In case of Classes V and VI camera monitor devices the instructions for use shall include a table that shows the minimum and maximum mounting height of the camera above ground under consideration of different viewing distances. The camera shall be mounted within the applicable height range. The viewing distances shall be selected from the intended context of use. The following table shows an example.

| Viewing distance | 0,5 m | 1,0 m | 1,5 m | 2,0 m | 2,5 m |
| --- | --- | --- | --- | --- | --- |
| Minimum mounting height | Para. 1.4.1 | Para. 1.4.1 | Para. 1.4.1 | Para. 1.4.1 | Para. 1.4.1 |

1.4.1.   The value of the minimum mounting height is the same for all viewing distances as it is independent of the viewing distance. It is determined by the dimensions of the field of vision and the field of view of the camera. Use the following working steps for determination of the minimum mounting height.

1.4.1.1.   Step 1: Draw the intended field of vision on ground.

1.4.1.2.   Step 2: Place the camera above the field of vision in such a way that the camera is viewing the field of vision. The lateral position shall be in accordance with the intended mounting position at the vehicle.

1.4.1.3.   Step 3: Change the height of the camera above ground in such a way, that the field of vision displayed on the monitor covers an area at least as large as the field of vision. Furthermore, the field of vision display should encompass the entire monitor screen.

1.4.1.4.   Step 4: Measure the height between camera and ground which is the minimum mounting height. Report the result value.

1.4.2.   The value of the maximum mounting height is different for different viewing distances as the displayed object size varies with the mounting height. Use the following working steps for determination of the maximum mounting height:

1.4.2.1.   Step 1: Determine the minimum width bmin of the critical object displayed on the monitor for each viewing distance.

Formula

Where:

| r | : | viewing distance in mm |
| --- | --- | --- |
| bmin | : | minimum width of the critical object displayed on the monitor in mm |

r

:

viewing distance in mm

bmin

:

minimum width of the critical object displayed on the monitor in mm

1.4.2.2.   Step 2: Place the critical object inside the drawn intended field of vision in a position at which the distance between the critical object and the camera is largest. The illumination conditions shall be in such a way that the critical object is clearly visible on the monitor.

1.4.2.3.   Step 3: Select the first value of the possible viewing distances.

1.4.2.4.   Step 4: Change the height of the camera above ground in such a way, that the residual width B of the object displayed on the monitor is equal to the minimum width allocated to that viewing distance.

Formula

Where:

| B | : | residual width of the object displayed on the monitor (which is ‘b’ in cases without smear and ‘b – s’ in cases with smear) in mm (see paragraph 1.1. General) |
| --- | --- | --- |

B

:

residual width of the object displayed on the monitor (which is ‘b’ in cases without smear and ‘b – s’ in cases with smear) in mm (see paragraph 1.1. General)

1.4.2.5.   Step 5: Measure the height between camera and ground which is the maximum mounting height allocated to that viewing distance. Report the result value.

1.4.2.6.   Step 6: Repeat the aforementioned steps 4 and 5 for the other viewing distances.
