1 Scope This document specifies procedures for determining the effect of temperature on tyre/road noise emission. Temperatures considered are tyre, road and ambient air temperatures . The noise emission for which this document is applicable is measured by means of ISO 11819‑2, or similar methods such as the on-board sound intensity (OBSI) method specified in Reference [1] . Measurement results obtained at a certain temperature, which may vary over a wide range, are normalized to a designated reference temperature (20 °C) using a correction procedure specified in this document.
