The applicability of this European Standard is described in the product standards for bituminous mixtures. WARNING — The method described in this European Standard may require the use of dichloromethane (methylene chloride), 1,1,1-trichloroethane, benzene, trichloroethylene, xylene, toluene, perchloroethylene (tetracloroethylene) or other solvents capable of dissolving bitumen. These solvents are hazardous to health and are subject to occupational exposure limits as detailed in relevant legislation and regulations. Exposure levels are related to both handling procedures and ventilation provision and it is emphasised that adequate training should be given to staff employed in the usage of these substances. 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, Turkey and the United Kingdom.

Note 1 to entry: The single test result may also be the mean of two or more observations or the result of a calculation from a set of observations as specified by the standard test method. 4 Preparatory treatment of laboratory samples of bituminous mixtures Prepare laboratory samples in accordance with EN 12697-28 to obtain suitable test portions. 5 Determination of binder content 5.1 General principles of test The test method for determining the binder content of a test portion of bituminous mixture, prepared in accordance with Clause 4, normally comprises the following basic operations: a) binder extraction by dissolving in a hot or cold solvent; SIST EN 12697-1:2012

NOTE The apparatus should be calibrated and traceable. 5.2.2.1 Balance, capable of weighing a test portion to an accuracy of 0,05 % of its mass. 5.2.2.2 Binder extraction apparatus, conforming to the requirements of the method selected from B.1, as appropriate. 5.2.3 Procedure 5.2.3.1 Prepare laboratory samples in accordance with EN 12697-28 to obtain suitable test portions. NOTE If determining binder content by difference, see Annex A. 5.2.3.2 Weigh the test portion to the nearest 0,05 % of the mass taken, and place it in the binder extraction apparatus in accordance with the requirements of the method selected from B.1, as appropriate. 5.2.3.3 The binder extraction procedure shall ensure that no soluble binder is left adhering to the aggregate particles after extraction. NOTE In limited cases, it may be difficult to dissolve every trace of binder adhering to the aggregate (see A.4). SIST EN 12697-1:2012

NOTE 1 In case of an oven, a temperature of (110 ± 5)°C is usually suitable. Where it is necessary to dry a test portion before analysis a temperature of (80 ± 5) °C may be more suitable to avoid binder drainage, but a longer time will be necessary. NOTE 2 In case of a drying cabinet lower temperatures are used. The lower the temperature, the longer it will take to dry to constant mass. NOTE 3 Constant mass is defined as successive weighings after drying at least 1 h apart not differing by more than 0,1 %. NOTE 4 For convenience, it is recommended that the successive weighings to determine constant mass should be carried out whilst the material is hot. It may be advisable to protect the balance from heat. 6.3.2 When constant mass has been achieved, cool in a moisture-free atmosphere and weigh. NOTE
A moisture-free atmosphere can be obtained by cooling in a desiccator. 7 Reporting of results 7.1 Results Report the soluble binder content, and, where appropriate: a) the water content to the nearest 0,1 % by mass in accordance with EN 12697-14; b) and/or the insoluble binder content in accordance with A.4. 7.2 Test report The report shall contain at least the following information in addition to that in 7.1: a) name and address of the testing laboratory;
b) unique serial number for the test report; c) name of the client; d) description and an identification of the sample, and the date of receipt; e) identification of the test method by reference to the Annex B apparatus used; f) any deviations, additions to or exclusions from the test method; g) whether or not the sample was accompanied by a sampling certificate; h) signature of officer accepting the technical responsibility for the test report; i) date of issue. 8 Precision data NOTE 1 Criteria for judging the acceptability of the binder content of bituminous mixtures determined by this European Standard are limited. The data that are tabulated herein were obtained from four separate precision experiments on SIST EN 12697-1:2012
