3 Term and definition
For the purposes of this document, the terms and definitions given in FprEN 15814:2011 and the following apply.
cold resistance
property of a bitumen sheet to resist cracking during bending tests at low temperatures
4 Principle
After preparing flexible sheets of the polymer-modified bitumen emulsion, the specimens are placed in a refrigerated box at a defined low temperature for a period of at least 1 h ± 10 mm.
After that time the specimens are bent around the bending steel.
5 Apparatus
5.1 Refrigerated box, the temperature of which can be regulated between (-10± 1)C and (+10± 1)°C
(minimum range).
5.2 Mandrel according to EN ISO 1519 of wood or steel with a diameter of 30 mm (see Figure 1).EN 15813-2011 pdf download.
