Passenger car tyres - Method for measuring relative wet grip performance - Loaded new tyres

This document specifies the method for measuring relative wet grip braking performance index to a reference under loaded conditions for new tyres for use on passenger cars on a wet-paved surface.The methods developed are meant to reduce variability. The use of a reference tyre is necessary to limit the variability of the testing procedures.This document applies to all passenger car tyres except for:—    special-use tyres marked with "ET";—    T-type temporary spare tyres;—    tyres fitted with additional devices to improve traction properties (e.g. studded tyres).

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
