1 Scope This European Standard specifies a method of exposing test specimens of plastic and rubber sheets for roofing free from all external restraint, to contact with bitumen at an elevated temperature and methods for determining the changes in properties resulting from such exposure. The methods for determination of changes in properties are specified as follows: a) changes in mass directly after contact with bitumen; b) changes in physical properties after contact with bitumen. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

4 General
The bitumen compatibility of sheets with an inner layer and EPDM sheets may be determined by a change in mass. The bitumen compatibility of sheets without an inner layer may be determined by the change in Young's Modulus. Results obtained by this test method from homogeneous sheets can be applied to sheets manufactured with same chemical formulation, but having inner reinforcement layers (e.g. fabric or non-wovens of polyester or mineral fibres). NOTE See also Annex A Sheets with a non-woven backing of at least 150 g/m² or equivalent, which prevents any contact of the waterproofing membrane with bitumen when installed in accordance with the manufacturer's instructions are considered to be bitumen compatible and may be declared as such by the manufacturer. The compatibility with bitumen is determined for the underside of the sheet as installed in accordance with the manufacturer's SIST EN 1548:2008

This European standard does not necessarily assess compatibility with bitumen on the upper face.
5 Principle A test specimen is exposed, on one face only, to contact with bitumen at 50°C for 28 days. Determination of properties is made before and after contact with bitumen. 6 Apparatus 6.1 Metal plate A rectangular metal plate measuring 400 mm x 350 mm x 2 mm. 6.2 Metal mask A rectangular metal mask 3 mm thick with outside dimensions of 280 mm x 220 mm and three inside windows of 200 mm x 80 mm each (see Figure 1). The beam width of the frame shall be 10 mm.
