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

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
