This document specifies methods for measuring tyre-to-road sound emissions from tyres fitted on a motor vehicle under coast-by conditions, i.e. when the vehicle is in free-rolling, non-powered operation. This is typically achieved by putting the transmission in the neutral or equivalent position and switching off the engine as well as all auxiliary systems not necessary for safe driving. This document is applicable to passenger cars and commercial vehicles as defined in ISO 3833. It is not intended to be used to determine the sound contribution of tyres of vehicles running in powered condition nor for the determination of traffic sound nuisance at a given location.

This document describes spare unit substitutive equipment (SUSE) for passenger car tyres, which is 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 document is intended only to qualify the performance of SUSE systems. Its specifications only apply to SUSE 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 document apply from the moment the SUSE system becomes effective, with the driver continuing to control 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 document: — the description of the various types of SUSE; — the description and performance levels of complete SUSE 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 the real operating conditions of the tyre in flat-tyre running mode. The following are outside the scope of this document: — 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 the 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 SUSE system, after it has been activated in flat tyre running mode.

ISO 19940:2017 specifies the testing method for determining the tyre stiffness index of passenger car tyres for the products capable of supplying the vehicle with the basic tyre functions, at least, at a speed of 80 km/h (50 mph) and a distance of 80 km when operating in flat tyre running mode, as per ISO 16992. This method is meant to determine the above mentioned index, for the characterization of the expected tyre's stiffness through its air and structural components. To reach the target, the vertical force and the vertical deflection, in the sense of absolute position in Z direction under different operating conditions, are measured (approximated in case of zero inflation pressure) and combined through the metrics defined in this document. This method is not intended to be used for conventional tyres.

This European Standard applies to the tyre pressure gauges (TPG) which operate using pressure equipment (devices used in fixed or mobile installations) to inflate the tyres of road using vehicles (M1 and M2 categories) and which may be capable of interacting with vehicles equipped with tyre pressure monitoring systems (TPMS) whereby the TPG may be steered by the TPMS/vehicle.
To set the correct tyre inflation, this European Standard defines requirements and processes for the interoperability of TPG with TPMS/vehicle, through standardized interfaces and data exchange formats allowing advanced information, management and control systems between TPG and TPMS/vehicle. The architecture is open and scalable to support the different levels of interoperability (from full interoperability to fully manual).
This European Standard does not define communication protocols (works specifically made under M/453 European mandate).
This European Standard may be applied to all TPG categories referenced in the revision of EN 12645.
The driver/operator is considered as being responsible for the validation of the parameters and tyre pressure.
This European Standard will be applicable upon development of Infrastructure solution (V2I-I2V communication solutions).

EN 12645 defines metrological and technical requirements and tests of tyre pressure measuring instruments. Tyre pressure measuring instruments (often referred to as Tyre Pressure Gauges, [TPG]) are for the inspection of pressure and/or inspection of inflation/deflation of tyres of motor vehicles. It establishes in the context of motor vehicles tyres, the minimum characteristics of the chain of measurement of tyre pressure measuring instruments intended to inspect or adjust the pressure of tyres inflated by air or nitrogen. These devices, classified in different categories, are hereinafter referred to by generic term, “tyre pressure measuring instruments”. This chain of measurement consists of all the elements between the tyre valve and the display device (connector, hose, control device, measurement components, reservoir, preset device etc.). They indicate the pressure difference (pe) between the air or the nitrogen in the tyre and the atmosphere. The field of application established above can be extended to other applications where no specific standard exists. Because of the influence of tyre pressure on road safety and energy efficiency, periodical verification of tyre pressure measuring instruments is strongly recommended.

The values obtained according to this method are not intended for use as levels of performance or quality. This International Standard is applicable to all motorcycle and moped tyres designed and intended for use on the road. NOTE Since most speedometers and odometers on motorcycles are activated from the front wheel, the test tyres will largely fall into sizes applicable for front wheel use. However, it is accepted that rear tyres will also be measured.

ISO 16992:2006 describes spare unit substitutive equipment (SUSE) for passenger car tyres. This equipment is designed to allow the user to continue on the journey (with or without a stop) in a reasonably safe manner. ISO 16992:2006 only aims to qualify the performance of extended mobility systems. It details specifications only for extended mobility systems suitable to permit the extended mobility of the vehicle. Other types of SUSE are described in the informative annexes. ISO 16992:2006 applies from the moment the extended mobility system becomes effective, and the driver has continued control of the vehicle (in speed and direction) in order to attempt to reach an appropriate place for servicing. ISO 16992:2006 does not cover the vehicle thus equipped; the tyre while operating in inflated mode; the characteristics of the pressure survey device and of the warning function relative to the 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. ISO 16992:2006 includes the description of the various types of SUSE; the description and performance levels of complete extended mobility systems.

ISO 23671:2006 specifies the method for measuring relative wet grip braking performance index to a reference under loaded conditions for new tyres for use on passenger cars on a wet-paved surface. The methods developed are meant to reduce the variability. The use of a reference tyre is necessary to limit the variability of the testing procedures. ISO 23671:2006 applies to all passenger car tyres.

ISO 5751-1:2004 gives guidelines for the design of, and specifies the designation and calculation of the dimensions for, metric-series motorcycle tyres. It is applicable to motorcycle tyres with a reduced height/width ratio (100 and lower) that can be fitted on cylindrical bead-seat or 5° tapered bead-seat rims. It is also applicable to other concepts of tyre and rim, provided the appropriate rim/section ratios and coefficients have been established for them.
