EN 12697-1:2012 (E) 4 Foreword This document (EN 12697-1:2012) has been prepared by Technical Committee CEN/TC TC “Road materials”, the secretariat of which is held by DIN. 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of an identical text or by endorsement, at the latest by December 2012, and conflicting national standards shall be withdrawn at the latest by December 2012. 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 12697-1:2005. Compared with EN 12697-1:2005, the following changes have been made: a) Removal of warning that the precision may be comprised with polymer-modified binders even when following Annex D;
b) For the separation of mineral, a note is added that the residue depends on the solvent and the equipment used; c) The desiccator is made optional with the method of achieving a moisture-free atmosphere not fixed; d) The definition of constant mass is changed; e) Alternative procedures for determination of binder are extended; f) Volume units are corrected from mm³ to 10³ mm³ as appropriate; g) In Annex B, note is added to ensure the binder is well dissolved; h) In Annex B, density of perchloroethylene is changed from (1,6 ± 0,05) g/cm³ at 24 °C to (1,6 ± 0,05) Mg/m³ at 20 ºC; i) In Annex B, weighing of multiple sieves that are fitted to the feed funnel is allowed; j) In Annex B, repeating the procedure with a second cup in the centrifuge is undertaken with half the flow rate; k) In Annex B, note is added that the second run is unnecessary for some centrifuges with larger capacities; l) In Annex C, M2 is clarified as being the mass of fine mineral matter; m) In Annex C, the procedures for collecting the recovered binder are clarified; n) In Annex D, a note is added that a good solubility of the polymer-modified binder does not always guarantee a good extraction of the PmB in the bituminous mixture; o) In Annex D, the discussion on different solvents is refined; p) In Annex D, the flow rate is adjusted rather than just checked to avoid overflowing; SIST EN 12697-1:2012
EN 12697-1:2012 (E) 5 q) In Annex D, the exceptions on the apparatus and procedure for the centrifuge extractor method are removed and notes added; r) In Annex D, note is added to continuous flow centrifuge; s) In Annex D, precision statement is changed.

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.

EN 12697-1:2012 (E) 8 Introduction This European Standard describes a unified approach to the examination of bituminous mixtures that allows some divergence in the detail of procedures followed by individual laboratories. In Clause 5 of this European Standard, a description is given of the basic operations that together form the test method for the proper determination of the binder content of bituminous mixtures. Guidance on the test method is given in Annex A and Figure A.1, while the use of alternative items of equipment that are equally suitable for carrying out particular parts of the test method are described in Annex B. Although the apparatus specified for the separation of mineral filler from the binder solution obtained after extraction is of a suitably efficient level not to affect the precision of the test described in Clause 8, a method for determining the amount of residual mineral matter in the extract is given in Annex C for use in those particular cases where some doubt may exist. Methods and equipment other than those described in Annex B and Annex C, including automated equipment, are permissible provided that they have been demonstrated to provide the same results as one of the methods in Annex B or Annex C within the limits of the precision given in this document. Guidance on determination of soluble binder content of mixtures with polymer-modified binders is given in Annex D. SIST EN 12697-1:2012
EN 12697-1:2012 (E) 9 1 Scope This document describes test methods for the determination of the soluble binder content of samples of bituminous mixtures. The test methods described are suitable for quality control purposes during the production of plant mix and for checking compliance with a product specification. For the analysis of mixtures containing modified binders, the guidance of Annex D should be followed. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

EN 12697-1:2012 (E) 10 Note 2 to entry: The measure of precision is usually expressed in terms of imprecision and computed as a standard deviation of the test results. Less precision is indicated by a larger standard deviation. Note 3 to entry: “Independent test results” means results obtained in a manner not influenced by any previous result on the same or similar test sample. Quantitative measures of precision depend critically on the stipulated conditions. Repeatability and reproducibility conditions are particular sets of extreme conditions. 3.4 repeatability precision under repeatability conditions 3.5 repeatability conditions conditions in which independent test results are obtained with the same method on identical test items in the same laboratory by the same operator using the same equipment within short intervals of time 3.6 repeatability limit maximum absolute difference between two test results obtained under repeatability conditions that may be expected
with a probability of 95 % Note 1 to entry: The symbol used for repeatability limit is r. 3.7 reproducibility precision under reproducibility conditions 3.8 reproducibility conditions conditions in which test results are obtained with the same method on identical test items in different laboratories with different operators using different equipment 3.9 reproducibility limit maximum absolute difference between two test results obtained under re…bility conditions that may be expected
with a probability of 95 % Note 1 to entry: The symbol used for reproducibility limit is R. 3.10 single test result value obtained by applying the standard test method once, fully, on a single specimen
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
