BS EN 13415-2010 pdf download.Test of adhesives for floor covering Determination of the electrical resistance of adhesive films and composites.
This BS EN 13415 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 reciprocal 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. R2 and R3 (see Clause 3). this method applies to the determination of the electrical resistance of adhesive films on glass and of composites of floor coverings, adhesively bonded to a fibre cement substrate R4 and R5 (see Clause 3).
