13、ional standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Interna
14、tional organizations, governmental and nongovernmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intende
15、d for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted.

20、ns of, for example, the close-proximity (CPX) method specified in ISO 11819-2. This method allows the user to make measurements within a wide air temperature range (5 C to 35 C) which means that temperature influence on the results may be substantial.In the CPX method, one or two reference tyres may
21、 be used, as specified in ISO/TS 11819-3; consequently, the temperature corrections need to be valid for these reference tyres. Tyre properties like rubber hysteresis and tread rubber hardness are affected by temperature, but the latter may also affect road surface properties. Temperature effects on
22、 noise, therefore, depend on both the tyre and the road surface, the temperatures of which are affected by ambient air temperature. To make it more complicated, the temperature probably has different effects on different noise generation mechanisms. Ideally, and whenever possible, temperature correc
23、tions shall be tailored to the tested tyre/road combination.The approach to the temperature correction in this document is semigeneric, which means that under certain conditions a correction to noise for temperature is made common to a group of tyres or a group of road surfaces. This document makes
24、a distinction to the two reference tyres and to a few major road pavement categories.
