ISO/TS 11819-3:2017 specifies two tyres intended to serve as reference tyres when using the close-proximity (CPX) method specified in ISO 11819-2.
The CPX method is a method for evaluating different road surfaces with respect to their influence on traffic noise, under conditions when tyre/road noise dominates. This method ideally re ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
