Download and print information about ISO and our services for measurement, certification, design, and construction of ISO tracks. The basic properties of the surface remain unchanged.

Such an instrument utilizes the two-microphone method for sound absorption. If the document is revised or amended, you will be notified by email. A test track fully meeting ISO is really a calibrated instrument for measuring vehicle noise. Add to Alert PDF.

Standards Subscriptions from ANSI provides a money-saving, multi-user solution for accessing standards. The principal objective is to provide a revised specification of the surface which improves the reproducibility of measurement. When you evaluate ISO for isp, the following test standards io used. For sound absorption, ISO Your Alert Profile lists the documents that will be monitored.

Transtec provides acceptance testing of new noise test tracks, and periodic checking of existing tracks at intervals required by the standard. In particular, the pavement surface texture affects the noise generated by the tires. The standard is a revised version of ISO Transtec utilizes RoboTex, a line laser-based robotic device.

Successful construction of an ISO track requires expertise in pavements and specifications that span surface texture, smoothness, iao noise.

Please first log in with a verified email before subscribing to alerts. Does my noise test track meet the requirements of the most recent version of the standard, ISO In order to minimize the variation in rolling sound emission and vehicle sound emission measurements made at different testing locations it is, therefore, necessary to iao exactly the relevant surface properties and specify carefully the properties of the materials, design and construction of the test surface.

Are you constructing a new pass-by noise test track, rehabilitating an existing track, or need your ISO test track certified? How do I explain to my construction contractor to deliver a pavement with sound absorption coefficient less than eight percent? The purpose of the ISO standard is to specify the noise test track in a manner that minimizes the variation of vehicle noise measurements made at different testing locations.

ISO Tracks: Specifications

The purpose of the ISO standard is to specify the noise test track in a manner that minimizes the variation of vehicle noise measurements made at different testing locations. Characteristics of a test track can significantly influence the exterior vehicle noise measurement. Photo courtesy of Spectronics, Inc. If you are an automotive company, a tire company, or a test track owner and you are involved with vehicle exterior noise measurements, then you must know about standard ISO In particular, pavement surface texture affects the noise generated by the tires.

If you are an automotive company, a tire company, or a test track owner and you are involved with vehicle exterior noise measurements, then you must know about standard ISO The shape, flatness, and sound absorption properties of the track affect how the sound propagates away from the vehicle.
