EN 12846-1:2011 (E) 3 Foreword This document (EN 12846-1:2011) has been prepared by Technical Committee CEN/TC 336 “Bituminous binders”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2011, and conflicting national standards shall be withdrawn at the latest by September 2011. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12846:2002. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive 89/106/EEC. This European Standard EN 12846 consists of the following parts under the general title Bitumen and bituminous binders – Determination of efflux time by the efflux viscometer: Part 1: Bituminous emulsions; Part 2: Cut-back and fluxed bituminous binders. EN 12846-1 has been created as the result of the merging of EN 12846:2002 and EN 13357:2002 under a single EN 12846 reference (two different parts), since both standards describe very similar procedures with identical equipment. The two different parts have been made as consistent as possible by eliminating all existing minor differences between both methods.
Compared with the previous edition, EN 12846:2002, the scope and principle were detailed, Figure 2 was added, tolerances were specified or modified in the apparatus dimensions, details were added in the test procedure and measurements made and the test precision data were reviewed. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
viscosity
internal resistance of a fluid to flow
3.2
efflux time
time needed for a specified volume of a material to flow through a specified orifice at a specified temperature
NOTE The efflux time is an indication of the pseudoviscosity, which is defined as the internal resistance to flow.
4 Principle
The viscosity of a bituminous emulsion is determined using an efflux viscometer known as the Standard Tar
Viscometer (STV) which determines the time of efflux of a 50 ml sample through a 10 mm or a 4 mm or a
2 mm orifice at a specified temperature.
Whatever temperatures or orifice diameters used, the efflux time shall not exceed 600 s. For highly viscous
emulsions, EN 14896 shall be used.

6 Apparatus
Usual laboratory apparatus and glassware, together with the following:
6.1 Efflux viscometer, (see an example of viscometer on Figure 1) consisting essentially of a cup with an
orifice in the centre of the base which may be closed by a ball-and-socket valve (see Figure 2). Three forms
are required, differing only in the size of the orifice (10 mm, 4 mm and 2 mm). For other dimensions of the cup
and the ball-valve, see Figure 3. The cup is a cylindrical brass tube with a dished phosphor-bronze bottom.
The ball valve consists of a phosphor-bronze ball on a rod of wrought nickel alloy with copper or rod of metals
NiCu30 in accordance with ISO 9722, with a level peg attached to the rod and a hemispherical top by means
of which the valve may be supported in a vertical position.
The viscometer cups shall be equipped with suitable corks for closing the orifices with the ball valve in
position, and some means of covering the cups (e.g. lids) to prevent evaporation of water.
The viscometer-cup holder shall be capable of:
