EN 12697-23:2017 (E) 3 European Foreword This document (EN 12697-23:2017) has been prepared by Technical Committee CEN/TC 227 “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of an identical text or by endorsement, at the latest by May 2018, and conflicting national standards shall be withdrawn at the latest by May 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12697-23:2003. The following is a list of significant technical changes since the previous edition: — the series title no longer makes the method exclusively for hot mix asphalt; — EN 12697-12 deleted as Normative reference, including any references to EN 12697-12 in this test method; — [5.2] addition of device for test specimen with diameter 80 mm and 120 mm;
— [5.2] Table 1 and Table 2 merged into one Table 1; — [6.2] addition of tolerances on diameter for specimens with diameter 80 mm and 120 mm; — [6.2] addition of maximum aggregate size for specimens with diameter 80 mm and 120 mm; — [6.5] introduction of requirements for specimen age; — [8] test temperature set to + 10 °C but opened by references from other standards; — [10] unit for ITS amended to kilopascals (kPa). Formula corrected accordingly; — [11] bullet g). Unit amended to kilopascals (kPa). According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
