Standard Practice for Calculating the International Runway Friction Index
|Publication Date:||10 June 2002|
|ICS Code (Other standards related to road engineering):||93.080.99|
This practice covers the calculation of the International Runway
Friction Index, IRFI, from
measurements obtained by local friction-measurement
The IRFI is the international friction index to be used for reporting the friction characteristics of airport movement areas.
The IRFI reported by this practice is a harmonized value of the pavement friction characteristics.
The IRFI obtained by using this practice has not been extended to address the braking performance of an aircraft.
The values stated in SI units are to be regarded as the standard. The values given in parentheses are provided for information only.
This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
