3 Terms and definitions
For the purposes of this European Standard, the following term and definition apply.
3.1
efflux time
time required for a specified volume of emulsion to flow out of the cup of a specified efflux viscometer
NOTE Efflux time gives an indication of the pseudoviscosity of a bitumen emulsion.
4 Principle
The efflux time of a bitumen emulsion is determined, using an efflux viscometer, as the time of efflux of a given
quantity of the emulsion through an orifice of a specified size at a specified temperature.
5 Reagents and materials
5.1 Light mineral oil
5.2 Solution Sa
An aqueous solution containing 1 % (m/m) of sodium lauryl sulfate or, failing that, an aqueous solution containing
1 % (m/m) of sodium oleate. In these solutions, 1 % (m/m) of sodium hydroxide shall be added.
This type of solution shall be used for testing anionic emulsions.

NOTE Solution Sa can be prepared also using potassium lauryl sulfate, potassium oleate and potassium hydroxide.
5.3 Solution Sc
An aqueous solution containing 1 % (m/m) of alkyltrimethylammonium chloride or 1 % (m/m) of
cetyltrimethylammonium bromide or, failing those, 1 % (m/m) of fatty amine hydrochloride. In these solutions,
1 % (m/m) of 1 mol/l hydrochloric acid shall be added.
This solution shall be used for testing cationic emulsions.
NOTE The aqueous solutions (5.2) and (5.3) can be replaced by aqueous phases of the same ionic structure as the tested
emulsion.
6 Apparatus
Usual laboratory apparatus and glassware, together with the following:
6.1 Efflux viscometer of the type shown in Figure 1, utilizing viscometer-cups with orifices of 10 mm, 4 mm or
2 mm in diameter fitted with a ball-and-socket valve of the appropriate size as indicated in Figure 2.
Choose the diameter of the orifice of the cup amongst the following conditions:
Table 1 – Diameter of the orifice of the cup
Orifice size, mm Efflux time, s
min max
10 and 4 5 Non continuous flow
2 5 Non continuous flow
The viscometer cups shall be provided with stoppers suitable for closing the orifices with the ball valve in position,
and some means of covering the cups to prevent evaporation of water.
The viscometer-cup holder shall be capable of:
supporting one or more cups in a vertical position;
providing a clearance of 280 mm ± 20 mm between the bottom of the orifice of the cup and the base on which
the holder stands;
providing a means of maintaining the test material in the cup at the test temperature during the period of efflux;
providing a valve support to hold the valve 16 mm ± 1 mm vertically above the orifice of the cup during efflux of
the test materia
