International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Sta

BS ISO 16992:2010ISO 16992:2010(E) iv ISO 2010 All rights reservedIntroduction In order to ensure unrestricted mobility, road vehicles need to be equipped with fully efficient tyres in all positions. Road vehicles are there

16、fore traditionally provided with a spare unit intended to reinstate vehicle mobility in the event of loss of efficiency of one tyre. The spare unit can be either of the following: of the same type of the units normally equipping the vehicle, or of “temporary use” type, thus intended for use only und

17、er restricted conditions. Some vehicles, however, can be constructed and provided with devices that can reinstate their mobility even in the absence of a spare unit on board. Various types of such devices (emergency solutions, products, systems) are available to users in order to ensure that they ar

18、e able to continue their journey in the event of loss of efficiency of one or more tyres. The term “spare unit substitutive equipment (SUSE)” (see definition 4.4) is used as a general name for all equipment intended to replace a spare unit on board the vehicle. The term “extended mobility system” (s

19、ee definition 4.5) refers to the assembly of several independent but interacting components specified and approved by a system manager. This International Standard mainly concerns the extended mobility systems for vehicles equipped with passenger car tyres, thus allowing driving to continue in restr

20、icted conditions after a loss of efficiency of at least one of the tyres of the vehicle. This International Standard specifies minimum performance levels for SUSE. It provides guidance when establishing objective requirements for a SUSE and allows the standard level of a given existing extended mobi

21、lity system to be determined. BS ISO 16992:2010INTERNATIONAL STANDARD ISO 16992:2010(E) ISO 2010 All rights reserved 1Passenger car tyres Spare unit substitutive equipment (SUSE) 1 Scope This International Standard describes spare unit substitutive equipment (SUSE) for passenger car tyres, which is

22、designed to enable users to continue their journey (with or without a stop) in a reasonably safe manner. NOTE 1 Certain equipment becomes effective automatically, thus avoiding the need to stop the vehicle immediately for inspection and corrective action. This International Standard is intended only

23、 to qualify the performance of extended mobility systems. Its specifications only apply to extended mobility systems that can permit the extended mobility of the vehicle. NOTE 2 Other types of SUSE are described in Annexes A and B. The specifications in this International Standard apply from the mom

24、ent the extended mobility system becomes effective, with the driver continuing to control of the vehicle (in terms of speed and direction) in an attempt to reach an appropriate place for servicing. The following are within the scope of this International Standard: the description of the various type

25、s of SUSE; the description and performance levels of complete extended mobility systems. NOTE 3 The performance level that the user reasonably has the right to expect, as well as the restrictive conditions placed upon that level, can vary to a large degree depending on the equipment installed and on

26、 the real operating conditions of the tyre in flat-tyre running mode. The following are outside the scope of this International Standard: the vehicle to be equipped; the tyre while operating in inflated mode; the characteristics of the pressure survey device and of the warning function relative to t

27、he inflated mode or to the partially deflated mode due to slow pressure losses; the transitory phase, if any, before the equipment becomes effective; the inspection, assessment, and the servicing of the extended mobility system, after it has been activated in flat tyre running mode.

28、0ISO 16992:2010(E) 2 ISO 2010 All rights reserved2 Conformance 2.1 When in inflated mode, and therefore functionally efficient, a tyre that is part of a SUSE shall conform in all respects to the usual criteria of a pneumatic tyre that can only be used in an inflated state, normal tyre load, i.e. it

29、shall conform to ISO 4000 (all parts) and to ISO 10191, and it shall be similarly maintained. The user shall therefore continue to comply with all recommendations of the tyre manufacturer, or the vehicle manufacturer, or both, as for a normal tyre. In particular, the cold inflation pressure of each

30、tyre shall be regularly checked. This check is necessary to ensure that it is at least adequate for the intended service (position, load, speed, camber, etc.) and that it conforms to the specifications of the tyre manufacturer, or the vehicle manufacturer, or both. 2.2 Whichever SUSE is chosen to eq

31、uip a vehicle, it shall not degrade the service properties of the tyre in inflated mode. 2.3 The performance of a SUSE depends upon the nature of the damage that was the cause of the loss of tyre functional efficiency. 2.4 Depending on the technical characteristics and functionality, a SUSE may offe

The driver can continue the journey, informed of the flat tyre running mode and aware of the expected performance level. An extended mobility system shall

Extended mobility systems shall activate automatically and include a run-flat warning system that warns the driver of the following: that the flat tyre running mode has been reached; any failure of the run-flat warning system. At the end of the specified performance of an extended mobility system, operating in flat tyre running mode, the loss of mobility shall not be immediate.
