Posted: Wed Sep 23, 2015 4:47 pmIP 72 VISCOSITY CUTBACK BITUMEN
Measure of the viscosity by determining the time of efflux of 50ml of a cutback bitumen, at 40°C (104°F), through a 10 mm orifice with efflux times in the range 15 to 500 sec.
EN 13398 DETERMINATION OF THE EFFLUX TIME OF PETROLEUM CUT-BACK AND FLUXED BITUMENS
Specifies a method for the determination of the efflux time of petroleum cut-back and fluxed bitumens in seconds using an efflux viscometer
EN 12846-1 DETERMINATION OF EFFLUX TIME BY THE EFFLUX VISCOMETER - BITUMINOUS EMULSIONS
For the determination of the efflux time at 40°C (104°F) of bituminous emulsions in seconds using an efflux viscometer. Alternative test temperature is 50°C (122°F)
EN 12846-2 DETERMINATION OF EFFLUX TIME BY THE EFFLUX VISCOMETER - CUT-BACK AND FLUXED BITUMINOUS BINDERS
For the determination of the efflux time at 25°C (77°F) of petroleum cut-back and fluxed bituminous binders in seconds using an efflux viscometer. Alternative test temperatures are 40°C (104°F) 50°C (122°F) and 60°C (140°F)
