Click to learn more. Pneumatic tyres as we know them today need the rubber materials and deformation to generate the required grip between vehicle and road surface, to give vehicle comfort and generate low rolling noise. In ISOseveral sources of variation are eliminated and parameters are defined more detailed. February Number of pages: The skimload level is defined: RRC is a dimensionless parameter that is well suited to compare tyres of different size, load index etc.

The faster, easier way to work lso standards.
Option to visualize changes at a glance. Each time they are deformed they dissipate energy: In total, this represents roughly 45 minutes.
Items to be considered when choosing a Reference Laboratory: This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. Several parameters are not defined in detail in the current ISO This is however essential to compare individual data vs.
ISO 28580: Information on Rolling Resistance (RR)
Published by Sheila Atkins Modified over 3 years ago. Tyre Labelling Tyres will be graded according to wet grip, fuel efficiency and external noise.
Friction There are many forms of friction. The machine alignment with the Reference Machine will be done using a linear regression see next page. An appropriate Reference Laboratory needs to be defined.
The choice of the 228580 Laboratory is very important. This shift depends on the absolute RR level as measured in the Reference Laboratory. If you wish to download it, please recommend it to your friends in any social system.
