Transtec provides acceptance testing of new noise test tracks, and periodic checking of existing tracks at intervals required by the standard. We have no amendments or corrections for this standard.
Subscription pricing is determined by: The latest version of ISO for pass-by noise test tracks has many requirements, some of which can be confusing.
If you are an automotive company, a tire company, izo a test track owner and you are involved with vehicle exterior noise measurements, then you must know about standard ISO This standard is also available to be included in Standards Subscriptions. Your Alert Profile lists the documents that will be monitored.
The standard is a revised version of ISO A test track fully meeting ISO is really a calibrated instrument for measuring vehicle noise.
Are you constructing a new pass-by noise test track, rehabilitating an existing track, or need your ISO test track certified? Successful construction of an ISO track requires expertise in pavements and specifications that span surface texture, smoothness, and noise. What Is Pavement Noise?
In particular, pavement surface texture affects the noise generated by the tires. 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.

When you evaluate ISO for conformance, the following test standards are used. Already Subscribed to this document. 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 describe exactly the relevant surface properties and specify carefully the properties of the materials, design and construction of the test surface.
Download and print information about ISO and our services for measurement, certification, design, and construction of ISO tracks. We can also assist in design and specifications for new or rehabilitated pass-by noise tracks and minimize your risk of not conforming to the ISO standard.
The basic properties of the surface remain unchanged. In addition, the skid resistance properties of the surface and its mechanical impedance may influence measured noise levels. For sound absorption, ISO Conformity testing to both the new ISO 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.

Impedance tube for pavement acoustic absorption. If you conduct automotive or tire testing following any of these standards, then your track needs to conform to ISO Our ISO conformance test services are capable of measuring them all, including macrotexture MPD using the profile method and sound absorption coefficient using the impedance tube method. For surface texture, ISO Such an instrument utilizes the two-microphone method for sound absorption.
Transtec utilizes RoboTex, a line laser-based robotic device.

In particular, the pavement surface texture affects the noise generated by the tires. Irregularity measurement of pavement courses: Does my noise test track meet the requirements of the most recent version of the standard, ISO The measurement is conducted in-situ, without the need for extracting core samples and the associated patching repairs. In addition, the variability of properties is reduced. Characteristics of a test track can significantly influence the exterior vehicle noise measurement.
This standard is not included in any packages.
