GB 26149-2017Performance requirements and test methods of tire pressure monitoring system for passenger cars (English PDF)

Foreword

Articles 4, 5, 6, 7 and 8 of this Standard are compulsory; and the rest are voluntary. This Standard was drafted in accordance with the rules given in GB/T 1.1-2009. This Standard replaces GB/T 26149-2010, TPM Sensor Module Based Tire Pressure Monitoring Systems for Motor Vehicles. Compared with GB/T 26149-2010, major changes of this Standard are as follows: -- the nature of the standard is changed from the former voluntary national standard into the compulsory national standard; -- the application scope is changed (GB/T 26149-2010 applies to the TPM module based tire pressure monitoring systems for vehicles and this Standard applies to vehicles of category M1); -- the classification of tire pressure monitoring systems is added; -- the functions and performance requirements are changed (GB/T 26149-2010 specifies the functions and of the TPM based tire pressure monitoring system and the performance requirements of relevant functions); -- the test methods are modified corresponding to the changes of functions and performance requirements; -- the requirements for the pressure monitoring system of the mandatory installation tires of vehicles of category M1. 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 the National Technical Committee of Auto Standardization (SAC/TC 114). The drafting organizations of this Standard.

The previous edition of the standard replaced by this Standard is as follows: -- GB/T 26149-2010. Performance Requirements and Test Methods of Tire Pressure Monitoring System for Passenger Cars

1 Application Scope

GB 26149-2017 is the Chinese national standard on performance requirements and test methods of tire pressure monitoring system for passenger cars, in the field of road vehicles engineering. It carries no /T suffix, which in the Chinese system means compliance is mandatory: a product or a practice within its scope has to meet it to be lawfully made, sold or carried out in China. It was issued on 14 October 2017 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 January 2018. Classification: ICS 43.040.10, CCS T35. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This Standard specifies the performance requirements and test methods of tire pressure monitoring system of passenger cars. This Standard applies to the vehicles of category M1.

3 Terms and Definitions

For the purposes of this Standard, the following terms and definitions apply.

3.1 tire pressure monitoring system; TPMS A system which is installed on the vehicle, monitors the tire pressure in some way and gives an alarm in case of any under-inflation of one or several tires.

3.2 recommended cold tire pressure; Prec The tire pressure value at the environmental temperature which is recommended by the vehicle manufacturer for the tires in different positions in accordance with the intended working conditions (such as load and vehicle speed), and causes no pressure accumulation because of use.

3.3 under inflation The tire pressure which is less than or equal to 75% of the recommended tire pressure (Prec) of the vehicle.

4 Classification

If the vehicle is equipped with one of the following two categories of TPMS, then it is deemed that the vehicle is equipped with the tire pressure monitoring system as defined by this Standard.

5 Functional and Performance Requirements

5.1 Electromagnetic compatibility The TPMS installed on the vehicle shall meet all the electrical/electronic requirements of ECE R10.

6 Test Conditions

6.1 Pavement and environment During the test, the pavement and environment shall be as specified in GB/T 12534.

6.2 Instruments The maximum tolerance for the pressure measurement device in the test shall be ± 3 kPa; all air pressure measurement data in the test shall be measured using one pressure measurement device.

7 Test Methods

7.1 Signalling device inspection test For the vehicle equipped with TPMS, conduct the signalling device inspection in the following test procedures.
