The modification of this Standard adopts ECE R12 The uniform stipulation protecting drivers from being injured by motor vehicle steering mechanism in the collision of motor vehicles (English version) (Revision 3 and all subsequent supplements, errata which were released prior to August, 2000). This Standard was redrafted based on ECE R12. Annex A lists comparison between clause numbers of this Standard and the ones of ECE R12. Technical differences between this Standard and ECE R12 as well as reasons are as follows. - this Standard deleted ECE R12’s Clause 3 “Certification application”, Clause 4 “Certification”, Clause 7 “Certification change and expansion of vehicle type and steering control type”, Clause 8 “Production consistency”, Clause 9 “Production inconsistency penalties”, Clause 10 “Instructions on use”, Clause 11 “Official discontinued production”, Clause 12 “Name and address of the certification testing department and the administrative department”, Clause 13 “Transitional provisions” and Annex 1 “Certification notice”, Annex 2 “Certification mark layout” because the standard system and the legal system were different and these were content related to “certification procedures and certification mark”; - this Standard deleted ECE R12’s 2.1 “Vehicle certification”, the term and definition of “Steering control certification” in 2.3 because the standard system and the legal system were different and these were content related to “certification procedures and certification mark”; - this Standard used Annex C of GB 11551-2003 to replace the content of “car riding position H and the actual back rest angle” in Annex 6 of ECE R12, so as to ensure that this Standard was consistent with the content of “the car ride position H and the actual back rest angle” in GB 11551-2003; - this Standard added the term and definitions of “R point” (see 3.17) in Clause 3 because R point of driver’s seat should be used during human body module impact test; - added the content of “at this time, the determination procedure of the dummy seat riding position H point and the actual seat back angle should be carried out according to Annex C of GB 11551-2003” in Annex B because the installation of the dummy during the test required adjustment of the seat condition; The stipulation protecting drivers from being injured by motor vehicle steering mechanism 1 Scope This Standard specifies technical requirements and test methods for driver's injury in the process of frontal collision of vehicle steering mechanism. This Standard is applicable to vehicles of M1 category and N1 vehicles of which the maximum total mass is less than 1500 kg. Other vehicles shall refer to this Standard to carry out the test. 2 Normative references The following standards contain the provisions which, through reference in this Standard, constitute the provisions of this Standard. For dated references, subsequent amendments (excluding corrections) or revisions do not apply to this Standard.

For a protrusion mounted on a rigid support, if its surface material is non-rigid material of which Shore (A) hardness is less than 50, it shall only apply to the rigid support part. 4.4.2 The design, construction and installation of steering control should ensure that during normal driving, there are no components which may hook the driver's clothing or other dressings and affect driver’s normal driving. 4.4.3 If it only inspects steering control, it shall carry out the test according to the provisions of C.2.1.3 and D.2.3 and meet requirements of 4.2 and 4.3. 4.4.4 For general steering control, it shall meet the following requirements. - the steering column shall meet the requirements at all angular positions, the test shall be carried out at least when the steering column is at the maximum angle and minimum angular position of all vehicles permitted to be installed; - when the test is carried out at all positions of the impactor and the human body module corresponding to the steering control, it shall be carried out at least in the worst position of which the steering control is mounted on the vehicle. 4.4.5 In order to facilitate the steering control connected with the steering column, it can use transition pieces; however, it should ensure the use of transition pieces has no effect on the energy absorption of the entire system. All tests can use the transition pieces of same type. 5 Test methods 5.1 In order to verify the compliance with the requirements of Clause 4, it shall carry out the tests according to the test methods specified in Annex B, Annex C and Annex D. All measurement should be conducted according to ISO 6487.2002. 5.2 An equivalent test approved by the relevant regulatory authority may be used. A test report including the test methods used and test results should be attached at the same time. Annex B (Normative) Frontal fixed barrier impact test B.1 Purpose This test is to verify if the vehicle meets requirements of 4.1. B.2 Installation, program and measuring instrument B.2.1 Test site The test site shall be large enough to accommodate runways, fixed barriers and technical equipment necessary for testing. The runway within at least 5 m long range from fixed barrier should be horizontal (the slope is less than 3% per 1m length), flat and smooth. B.2.2 Fixed barrier It is made of reinforced concrete. The front width shall not be less than 3 m, the height not less than 1.5 m; barrier thickness should ensure that its quality is not less than 7 × 104 kg. Its front surface should be smooth, vertical and orthogonal to the runway and the surface should cover (19 ± 1) mm thick quality plywood. In the middle of the reinforced concrete structure and plywood, it can also be placed with a steel plate of at least 25 mm thickness. It can use other collision barrie... ......
