15、ariat of which is held by BSI. This document was submitted to the formal vote and approved. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by February 1995, and conflicting national standards shall
16、be withdrawn at the latest by February 1995. In accordance with the CENNENELEC Internal Regulations the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal,
17、Spain, Sweden, Switzerland and United Kingdom. 1 Scope This European Standard specifies a method for determining the shear force of layers of a resilient floor covering. 2 Definition For the purposes of this standard, the following definition applies. shear force The force applied parallel to a resi
18、lient floor covering which causes separation between or in its layers. 3 Principle A test piece is struck between two plates such that an overlap of 2 O00 mm2 shear surface is obtained. The test piece is then tom parallel to the surface of the plates, in a tensile testing machine. 4 Apparatus and ma
19、terial 4.1 Apparatus 4.1.1 Rigid plates, e.g. plywood, metal, of minimum dimensions 100 mm x 50 mm. 4.1.2 A tensile testing machine with suitable load cell and recording device. 4.2 Material 4.2.1 Adhesive(s), which shall not penetrate deeply into the integral backing or alter the constituents of th
20、e test piece, e.g. two part epoxy adhesive. 5 Sampling and preparation of test pieces b) a complete identification of the product tested, including type, source, colour and manufacturers reference numbers; c) previous history of the sample; d) the mean value for shear force in each direction; e) if
21、adhesive failure occurred; f) any deviation from this standard which may have affected the results. -_-_- *CEN EN*432 74 W 3404587 0073537 832 W BS EN 432: 1994 National annex NA (informative) Committees responsible The United Kingdom participation in the preparation of this European Standard was en
