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.
Specifies a method for the determination of the efflux time of petroleum cut-back and fluxed bitumens in seconds using an efflux viscometer

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)

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)
