3 Definition
This standard uses the following definition:
3.1 Rearview mirror
A device that can reflect a clear image of the rear of a car within a specified field of
view (but does not include complex optical systems such as periscopes). It is generally
composed of lenses, retaining parts, direction adjustment parts, brackets, etc.
3.1.1 Interior rearview mirror
Rearview mirror installed inside the car.
3.1.2 Exterior rearview mirror
A rearview mirror installed outside the car.
3.1.3 Monitoring mirror
A rearview mirror mounted on the outside of a car, to monitor the situation below or
around the car.
3.2 Plane mirror
Refers to a mirror with a flat reflective surface.
3.3 Convex mirror
It refers to a curved-surface mirror whose reflective surface is spherical or aspherical.
3.4 Reflectivity variable rearview mirror
It refers to an anti-dazzle rearview mirror, that can reduce reflectivity when driving at
night and is affected by the glare of the headlights of following vehicles. Prisms also
fall into this category.
4 Requirements
4.1 The rearview mirror shall be easy to be adjusted and maintained in the normal
direction of use. In normal use, each component must not have sharp protrusions.
4.2 General requirements
Rearview mirror retainers, brackets and other parts need to be subject to anti-glare
treatment.
4.2.1 The bracket of the rearview mirror shall be able to install and maintain it in the
normal use position. If necessary, it shall be equipped with an impact buffer mechanism.
4.2.2 Variable reflectivity rearview mirrors shall have a mechanism to switch
reflectivity between day and night.
4.2.3 The glass used in the rearview mirror must comply with the mirror-making grade
requirements of GB 11614.
4.2.4 Other requirements shall comply with the requirements of 4.1 in GB 15084.
4.3 Appearance requirements
4.3.1 Under the illumination condition of 500 1x, at a distance of 500 mm from the
naked eye, when observing the mirror surface from a 45° direction, there shall be no
provisions of 5.7, the mirror surface shall not be blurred or aged; other parts shall not
cause obvious fading, cracks, deformation and other defects.
4.4.8 Impact buffering performance
4.4.8.1 Necessary conditions
The impact buffering performance of the rearview mirror means that when the rearview
mirror is installed according to the actual vehicle condition; the interior rearview mirror
shall meet the performance specified in 4.4.8.2; the exterior rearview mirror and
surveillance mirror shall meet the performance specified in 4.4.8.3. This article does
not apply to the following aspects.
4.4.8.1.1 For the interior rearview mirror, it is located outside the collision area of the
occupant's head in GB 11552.
4.4.8.1.2 External rearview mirrors and surveillance mirrors:
a) Located within the outermost line of the vehicle body near the mounting base;
b) When the vehicle is fully loaded, the bottom edge of the exterior rearview mirror
and surveillance mirror is more than 1800 mm from the ground;
4.4.8.2 Impact buffering of interior rearview mirror
When the interior rearview mirror is tested according to the impact test method in 5.8.1,
the pendulum falls freely from a position of 60° relative to the plumb line and hits the
interior rearview mirror on a vertical plane, which is parallel to the longitudinal
centerline of the vehicle. The swing angle of the hammer relative to the plumb line shall
not be less than 20°. If any parts are damaged, there must be no sharp protrusions.
Other relevant requirements shall comply with the provisions of GB 15084.
4.4.8.3 Impact buffering of exterior rearview mirrors and surveillance mirrors
When the exterior rearview mirror and surveillance mirror are tested according to the
impact test method in 5.8.2, the pendulum falls freely from a position of 60° relative to
the plumb line and hits the rearview mirror on a vertical plane, which is parallel to the
longitudinal centerline of the vehicle. The swing angle of the pendulum relative to the
plumb line shall not be less than 20°. If any parts are damaged, there must be no sharp
protrusions.
Other relevant requirements shall comply with the provisions of GB 15084.
4.4.9 Corrosion resistance
The anti-corrosion coating (plating) layer of the rearview mirror shall comply with the
