AUTOMOTIVE INDUSTRY STANDARD - ARAI India

1 AIS-150 I AUTOMOTIVE INDUSTRY STANDARD Requirements for Approval of Vehicles of Categories M2, M3, N and T with Regard to braking PRINTED BY THE AUTOMOTIVE RESEARCH ASSOCIATION OF India NO. 832, PUNE 411 004 ON BEHALF OF AUTOMOTIVE INDUSTRY standards COMMITTEE UNDER CENTRAL MOTOR VEHICLE RULES TECHNICAL STANDING COMMITTEE SET-UP BY MINISTRY OF ROAD TRANSPORT & HIGHWAYS (DEPARTMENT OF ROAD TRANSPORT & HIGHWAYS) GOVERNMENT OF India May 2018 AIS-150 II Status chart of the STANDARD to be used by the purchaser for updating the record Sr. No. Corrigenda.

2 Amendment Revision Date Remark Misc. General remarks : AIS-150 III INTRODUCTION The Government of India felt the need for a permanent agency to expedite the publication of standards and development of test facilities in parallel when the work on the preparation of the standards is going on, as the development of improved safety critical parts can be undertaken only after the publication of the STANDARD and commissioning of test facilities.

3 To this end, the erstwhile Ministry of Surface Transport (MOST) has constituted a permanent AUTOMOTIVE INDUSTRY standards Committee (AISC) vide order No. RT-11028/11/97-MVL dated September 15, 1997. The standards prepared by AISC will be approved by the permanent CMVR Technical Standing Committee (CTSC). After approval, the AUTOMOTIVE Research Association of India , (ARAI), Pune, being the Secretariat of the AIS Committee, has published this STANDARD . For better dissemination of this information ARAI may publish this STANDARD on their web site.

4 This STANDARD covers requirement for M2, M3 and N category of vehicles. For N1 category manufacturer has an option to test their vehicles as per AIS-151 or this STANDARD . An informative Annex X has been incorporated in this document indicating corresponding clauses of this document and UN R 13 (Revision 8 Amendment 4). This STANDARD is aligned with UN R 13 (Revision 8 Amendment 4). However, keeping in view Indian context this STANDARD is having following differences as compared to UN R: a) Trailers are designated as T against O b) Coefficient of adhesion of road surface to be at least whereas in ECE requirement is given as subjective.

5 C) Type II A test is applicable only for few categories of vehicles d) Additional India specific requirements are added as below: 1) Drive away chassis test procedure; 2) Criteria for extension of approval to be used for selection of vehicle for testing and extension of approvals added; 3) Test procedure Annex added to avoid interpretation issue; and 4) Tolerance on test speed added to 2 percent; e) Requirements of adhesion utilization for N1 & N2 category vehicles have been kept in abeyance till the time ABS is made mandatory for these vehicles. f) For clarity the testing procedure is given in Annex B which also contains the requirements described in other Annexes.

6 Hence there is a possibility of duplication in case of duplication; whatever is prescribed in Annex B overrides the others. The AISC panel and the AUTOMOTIVE INDUSTRY standards Committee (AISC) responsible for preparation of this STANDARD are given in Annex-Y and Annex-Z respectively.

10 This STANDARD does not cover: a) Vehicles with a maximum design speed not exceeding 25 km/h, b) Trailers which may not be coupled to power-driven vehicles with a design speed exceeding 25 km/h, and c) Vehicles fitted for invalid drivers. Subject to the applicable provisions of this STANDARD method of measuring reaction (response) times in brakes other than compressed-air brakes are not covered by this STANDARD . NOTE AIS 151 is prescribing alternate performance requirements for vehicle categories N1. Vehicle manufacturer may opt for compliance to AIS 151 instead of AIS 150.
