20、2697-1:2012 (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 endorseme
21、nt, at the latest by December 2012, and conflicting national standards shall be withdrawn at the latest by December 2012.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 identif
22、ying 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 compromised with polymer-modified binders even when following Annex D; b) For the separation of mineral,
23、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)
24、Volume units are corrected from mm to 10 mm 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/cm at 24 C to (1,6 0,05) Mg/m at 20 C; i) In Annex B, weighing of multiple sieves that are fitted
25、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, M2is clarified as being the mas
26、s 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 discuss
27、ion on different solvents is refined; p) In Annex D, the flow rate is adjusted rather than just checked to avoid overflowing; BS EN 12697-1:2012EN 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 An
28、nex D, note is added to continuous flow centrifuge; s) In Annex D, precision statement is changed.
