Foreword
Clause 4, Clause 5 and Clause 6 of this Standard are compulsory; the rest are
recommendatory.
The standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces GB 15084-2006 “Motor Vehicles - Rear View Mirror -
Requirements of Performance and Installation”.
Compared with GB 15084-2006, the main technical changes are as follows.
- In application scope, it added requirements and installation on indirect
vision of Class L motor vehicles of which the cabin is at least partially
enclosed.
- Added definitions of “devices for indirect vision”, “camera-monitor devices
for indirect vision”, “video camera”, “monitor”, “resolution rate”, “critical
object”, “critical field of vision”, “detection distance”, “critical field of vision”,
“viewing reference point”, “visible spectrum”, “other devices for indirect
vision”, “camera-monitor-recording device”, “type of devices for indirect
vision”, and “flat type” (referring to 3.1, 3.17~3.22, and 3.24~3.31).
- Added technical requirements, experimental method and installation
requirements as well as vision requirements for front view mirrors of Class
“VII” [referring to 4.1.2.1.5, 4.1.2.2.2.3d) and Table 2, 6.3,.7 and 6.5.7];
- Added technical requirements, test methods, installation requirements as
well as vision requirements for motor vehicles of Class L of which the cabin
is at least partially enclosed [referring to 4.1.1.5, 4.1.2.1.6, 4.1.2.2.2.3c),
6.2.1.3, 6.2.1.4, 6.5.8,6.5.8.1, 6.5.8.2, Figure 10];
- Modified curvature radius of view mirrors of Class II, Class IV and Class V
[ 4.1.2.2.2.3h) and 4.1.2.2.2.3c] of this edition]; referring to 5.2.3.2 and
5.2.3.3 of edition 2006];
- Added requirements for devices of indirect vision except view mirror (4.2 of
this edition);
- Modified the number of installation and requirements for view mirror vision
(Table 2 of this edition; referring to Table 2 of edition 2006);
- Modified the content of experimental requirements; deleted “except
close-proximity rear view mirror (Class V)”, all rear view mirrors shall
receive the tests stipulated in 6.2 and 6.3; increased view mirrors of “Class
I ~ Class VI” shall also include view mirrors of Class VII used for vehicles
- Units involved in this Standard were all replaced by “mm”;
- Added informative Appendix A.
This Standard was proposed by the Ministry of Industry and Information
Technology of the People’s Republic of China.
This Standard shall be under the jurisdiction of National Technical Committee
of Auto Standardization (SAC/TC 114) .

This Standard replaces the following previous standards.
- GB 15084-1994, GB 15084-2006.
Motor Vehicles - Devices for Indirect Vision -
Requirements of Performance and Installation
1 Scope
This Standard specifies indirect motor vehicle devices of Class M, Class N and
Class L of which it has less than four wheels and the cabin is at least partially
enclosed.
This Standard applies to the installation of indirect motor vehicle devices of
Class M, Class N and Class L of which the cabin is at least partially enclosed.
2 Normative references
The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including
any amendments) applies.
GB/T 15089 Classification of power-driven vehicles and trailers
ISO 15008.2003 Road vehicles - Ergonomic aspects of transport
information and control systems - Specifications and compliance
procedures for in-vehicle visual presentation
EN 12368.2006 Traffic control equipment - Signal heads
3 Terms and definitions
For the purpose of this Standard, the following terms and definitions shall
apply.
3.1 Devices for indirect vision
Devices used to observe adjacent traffic area of vehicle that cannot be
observed through direct vision. They may include conventional optical view
mirror, video camera-monitor or other devices that can provide information on
indirect vision to drivers.
3.2 View mirror
A device of turning a kind of signal into the image of visible spectrum.
3.20 Resolution
Being able to discern the smallest details of the object, i.e. being able to
discern the smallest portion of the object.
Note. Resolution of human eyes is called “visual sensitivity”.
3.21 Critical object
Circular object of which the diameter D0 is 800mm.
Note. Use indirect vision system to observe target objects which represent relevant
road users. Correlation of road users is defined by the location and (possible) speed.
Size of road users will be enlarged with speed acceleration. For viewing, it is provided
that motor cyclist at a distance of 40,000 mm is equivalent to the pedestrian
(D=500mm) at a distance of 25,000 mm. Taking into account of speed, identify the
size of motor cyclist as the size standard of target object observed. For this reason,
determine the circular object of which the diameter is 800mm as the standard size of
target object observed.
3.22 Critical perception
Visual level that human eyes generally achieve under various conditions.
Under traffic conditions, the limiting value of critical field of vision is 8 arc
minutes of angle of view.
3.23 Field of vision
The scope of three-dimensional space that can be observed by means of
devices for indirect vision. It is based on ground view provided by the device
and may be defined on the basis of device applicable maximum detection
distance.
3.24 Detection distance
Measuring distance on the ground from viewing reference point to the farthest
point where critical object can be seen (the limiting value of just reaching
critical field of vision).
3.25 Critical field of vision
The area where critical object may be observed through the devices for
indirect vision. It is defined by one angle and one or more detection distances.
3.26 Viewing reference point
4.1.1.2 The edge of reflecting surface shall be enclosed in a protective frame
(e.g. stand, etc.). Radius of curvature C of all points in the periphery of
protective frame shall be greater than or equal to 2.5mm in any direction. If the
reflecting surface is beyond the protective ...
