Foreword
The Clause 4, 5, 6 of this Standard are mandatory, while the rest are
recommended.
This Standard was drafted as per the rules specified in GB/T 1.1-2009.
This Standard replaced GB 11562-1994 Motor Vehicles – Forward Visibility for Drivers
– Requirements and Measurement Methods; the major differences between this
Standard and GB 11562-1994 are as follows.
a) Delete GB/T 11563 Motor Vehicles – Procedure for H-Point Determination, GB/T
11559 Motor Vehicles – Use in Defining their Seating Accommodation – Three-
Dimensional H-Point Machine (these two standards are obsolete) from the
normative references;
b) Change the term of “three-dimensional coordinate system” in the original
standard into “three-dimensional reference gird”; and add the following terms and
definitions.
--- Vehicle type with regard to the field of vision (see Sub-clause 3.1);
--- Armoured vehicle (see Sub-clause 3.11);
--- Extended seat-adjustment range (see Sub-clause 3.18);
--- The angle of obstruction of the A pillar on the driver’s side (see Sub-clause
3.19);
--- The angle of obstruction of the A pillar on the passenger side (see Sub-clause
3.20);
--- Area “S” (see Sub-clause 3.21);
--- Reference data (see Sub-clause 3.22);
--- Three-dimensional H point machine (see Sub-clause 3.23);
--- Torso-line (see Sub-clause 3.24);
--- Center plane of occupant (see Sub-clause 3.25);
--- Fiducial marks (see Sub-clause 3.26);
--- Vehicle measuring attitude (see Sub-clause 3.27);
c) Add the technical requirements for “armoured (bulletproof) vehicle” (see Sub-
clause 4.2 of this Standard; Sub-clause 5.1.2 of ECE R125)
d) Add the requirements for steering wheel adjustable vehicle (see Sub-clause
4.4.1 of this Standard; Sub-clause 5.1.3.1 of ECE R125)
This Standard adopts the re-drafting method to modify and use the Economic
Commission for Europe ECE R125 Rev.2/Add.124/Amend.3 (2011 Edition) Uniform
Provisions Concerning the Approval of Motor Vehicles with regard to the Forward Field
of Vision of the Motor Vehicle Driver.
The comparison list between the clause numbers of this Standard and clause number
of ECE R125 Regulation can refer to Appendix A of this Standard.
The technical differences and causes between this Standard and ECE R 125
Regulation are as follows.
--- Delete Sub-clause 1.2, 1.3 in Clause 1 of ECE R125 for the purpose of satisfying
the rules of GB/T 1.1-2009, and meeting the requirements for motor vehicles
driving on the right side of the road in China.
--- Delete Clause 3 “Application for Certification”, Clause 4 “Certification”, Clause 7
“Changes and Expansion of Vehicle Types”, Clause 8 “Production Consistency”,
Clause 9 “Punishment on Non-Production Consistency”, Clause 10 “Shut down”,
Clause 11 “Addresses and Names of Testing Agencies and their Administrative
Agencies”, information of manufacturer applying for certification in Annex 1,
format of certification marks in Annex 2, etc. for the purpose of keeping
consistent China’s motor vehicle management system, and for the benefit of the
implementation and operation of this Standard.
For the sake of usage, the following editorial changes are made against the ECE R125
Regulation.
a) Change cm2 into mm2;
b) Add informative appendix.
This Standard was proposed by Ministry of Industry and Information Technology of the
People’s Republic of China.
This Standard shall be under the jurisdiction of National Technical Committee for
Standardization of Automobiles (SAC/TC 114).
Drafting organizations of this Standard. Dongfeng Motor Corporation, Natinoal
Automobile Quality Supervision and Test Center (Xiangyang), China FAW Co., Ltd.

Motor Vehicles forward Visibility for Drivers
- Requirements and Measurement Methods
1 Scope
This Standard specifies the requirements and measurement methods of the direct
visual filed within 180° range in front of the driver.
This Standard is applicable to the Type-M1 automobile.
2 Normative References
The following documents are essential to the application of this document. For the
dated documents, only the versions with the dates indicated are applicable to this
document; for the undated documents, only the latest version (including all the
amendments) are applicable to this document.
GB 11555-2009 Motor Vehicles- Windshield Demisting and Defrosting Systems –
Performance Requirements and Test Methods
3 Terms and Definitions
The following terms and definitions are applicable to this document.
3.1 Vehicle type with regard to the field of vision
The vehicles with no difference in the following aspects.
--- The external and internal shapes and arrangement that may influence the field
of visions within 180° range in front of the driver;
--- Shape, dimension and installation mode of front windshield glass.
3.2 Three-dimensional reference grid
The coordinate system consisting of three orthogonal datum planes that is determined
by the vehicle manufacturer at the initial design stage (see Figure B.1). These three
datum planes are as follows.
X datum plane --- vertical plane perpendicular to the Y datum plane; usually defined
by passing the left and right front wheel center;
Y datum plane – vehicle longitudinal symmetry plane;
Z datum plane – the horizontal plane perpendicular to the Y and X datum planes.
The three-dimensional coordinate system is used to determine the dimension
relationship between the positions of design points on the drawing and the positions of
these points on the vehicle.
The coordinate value relevant to zero plane shall be determined on the basis of vehicle
running state plus a front passenger [passenger mass is (75±1) kg].
If the vehicle is equipped with an adjustable clearance suspension away from the
ground, it shall be tested in the state of normal use specified by the vehicle
manufacturer.
3.3 Primary reference marks
The holes on the vehicle body, surface, mark, identification symbols. The type of used
reference marks and the positions of each mark on the X, Y, Z coordinates of the three-
dimensional coordinate system, and on the relative design ground level shall be
specified by the vehicle manufacturer. These reference marks can be us...
