ÖNORM EN 12607-3

This European Standard specifies a method for measuring the combined effects of heat and air on a thin moving film of bitumen or bituminous binder, simulating the hardening that a bituminous binder undergoes during mixing in an asphalt mixing plant. The method is referred to as RFT, i.e. Rotating Flask Test. WARNING Use of this European Standard can involve hazardous materials, operations and equipment. This European Standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this European standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. If there is a likelihood of volatile components being present in a binder, this procedure should not be used. It should not be used for cut-back bitumen or bituminous emulsions before these products have been stabilised, e.g. in accordance with EN 14895.
