19、 and the United Kingdom. BS EN 13415:2010EN 13415:2010 (E) 4 1 Scope This European Standard specifies a test method to measure the electrical resistance as a material physical parameter of an adhesive film and composites of floor covering material and adhesive film. The electrical resistance is reci
20、procal to the electrical conductivity. This laboratory method does not take account of all influences which may occur in practice. In contrast to EN 1081, which applies to the determination of the electrical resistance of resilient floor coverings R1, R2and R3(see Clause 3), this method applies to t
21、he determination of the electrical resistance of adhesive films on glass and of composites of floor coverings, adhesively bonded to a fibre cement substrate R4and R5(see Clause 3). 2 Normative references The following referenced documents are indispensable for the application of this document.
