European Foreword
This document (prEN 12697-23:2025) has been prepared by Technical Committee CEN/TC 227 “Road
materials”, the secretariat of which is held by BSI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 12697-23:2017.
prEN 12697-23:2025 includes the following significant technical changes with respect to
EN 12697-23:2017:
— [Clause 5.3] the wording, “accuracy of ± 0,2 kN”, amended to read “nearest 0,1 kN with a maximum
permissible error of 0,2 kN”;
— [Clause 5.4] amended to read: “Water bath, thermostatically controlled, or air chamber, capable of
maintaining the temperature in the vicinity of the specimen within ± 1 °C from the test temperature.”
— [Clause 7]. Subclause 7.1 and 7.2 deleted and merged under Clause 7. Completion with following
paragraph: “Bring the test specimen to the selected test temperature selected according to Clause 8
with a maximum permissible error of 1 °C. “;
— [Clause 8] deletion of 1st paragraph: “Unless defined elsewhere, the test temperature shall be (10 ±
2) °C. Replaced by: “The test temperature shall be selected between +5 °C to +25 °C”;
— [Clause 8], 2nd paragraph. Last two sentences deleted. 1st sentence reworded to NOTE;
— [Clause 9.1] Deletion of paragraph: “The testing machine shall be placed in a room with temperature
between 15 °C and 25 °C.;
— [Clause 10] Rounding of ITS changed to the nearest kPa instead of three significant figures.
