A comparison between the two methods is given in informative Annex D

NOTE 2 The examples suggest the spectrum of possibilities both in application area and in choice of fractional factorial designs

Bitumen and bituminous binders. Determination of the resistance to hardening under influence of heat and air - TFOT method Ingestion-build-135476 This part of ISO 100711 Scope This part of EN 12607 specifies a method for measuring the combined effects of heat and air on a film of bitumen or bituminous binder, simulating the hardening which most bituminous binders undergo during mixing in an asphalt mixing plant. The method is suitable for other bituminous binders than paving grade bitumen, but the reference temperature might give excessive hardening that does not resemble real conditions during mixing at the plant.
