19、dorsement, at the latest by April 2003, and conflicting national standards shall be withdrawn at the latest by April 2003. This European Standard is one of a series of standards which specify test methods for determining dimensions and properties of thermal insulating materials and products. It supp
20、orts a series of product standards for thermal insulating materials and products which derive from the Council Directive of 21 December 1988 on the approximation of laws, regulations and administrative provisions of the Member States relating to construction products (Directive 89/106/EEC) through t
21、he consideration of the essential requirements. This European Standard has been drafted for applications in buildings but may also be used in other areas where it is relevant. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound
22、 to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.

30、rolled Copy, (c) BSI EN 13494:2002 (E) 5 4 Principle The tensile bond strength of the adhesive and of the base coat to the thermal insulation material are determined by a direct load perpendicular to the surface of the adhesive or the base coat. The tensile load is applied by means of a rigid plate
31、glued to the test area of the adhesive or base coat. 5 Apparatus 5.1 Glue The glue shall be suitable for rough surfaces (render surface) and for timber (e.g. solvent free epoxy adhesive or polyurethane adhesive). The glue shall not damage the thermal insulation material, the base coat or the adhesiv
32、e and not influence the results. 5.2 Rigid plates The rigid plates (e.g. plywood of thickness 20 mm or steel plates of thickness 5 mm) shall have dimensions of (200 2) mm (200 2) mm. The mechanical stability or the rigid plates shall not influence the test results. They shall have a central fitting
33、for the connection to the testing machine providing a self aligning attachment to avoid uneven distribution of tensile stress during the test. On the side to which the glue is to be applied, the plates shall be flat with a tolerance of + 0,5 mm per 100 mm length. 5.3 Saw Mechanical driven saw (e.g.
34、circular saw or band saw) with guides for a rectangular cut. The saw shall be suitable for sawing test specimens from hardened adhesive or base coat with the reinforcement. 5.4 Tensile testing machine The tensile testing machine, appropriate for the range of force and displacement involved, capable
35、of having a constant crosshead speed adjusted to (10 + 1) mm/min and suitable for testing specimens with the dimensions of 200 mm 200 mm. It shall be capable of measuring the force with an error limit of at least 1 % (see EN 1607). 6 Test specimens 6.1 Preparation of the samples The adhesive, or bas
36、e coat with the reinforcement, is applied in accordance with the manufacturers instructions on to the surface of thermal insulation material having minimum dimensions of 500 mm 1000 mm 60 mm. The samples shall not include mechanical fixings. 6.2 Conditioning of the samples The conditioning of the sa
37、mples shall be carried out as specified in the relevant ETICS product standard. NOTEIn the absence of a product standard for ETICS or any other European technical specification, the conditioning procedure may be agreed between parties. 6.3 Preparation and number of test specimens Cut three square sh
38、aped test specimens of dimensions 200 mm 200 mm out of the samples. A minimum distance of 100 mm to the edges of the samples shall be maintained. The thickness of the adhesive or of the base coat shall be measured visually and rounded to the nearest mm. Apply a thin layer of glue to both surfaces of
39、 the test specimen in such a way that the glue forms a complete layer between the rigid plates and the test specimen. With slight pressure glue the rigid plate on to the test specimen Licensed Copy: sheffieldun sheffieldun, na, Mon Oct 30 09:34:14 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 13494:

Allow the glue to harden in accordance with the manufacturers instructions. 7 Procedure 7.1 Test conditions The tes

43、ure 1 Attachment of the test specimen to the tensile testing machine 7.3 Test procedure Carry out the tensile bond strength measurement as described in EN 1607 until failure occurs. Apply the tensile load perpendicular to the test area through the rigid plates by means of the tensile testing machine
44、. Increase the load with a constant crosshead speed adjusted to (10 + 1) mm/min. Record the tensile force at failure. Reject any test where the mode of failure is a fracture at the glue layer between the test specimen and the rigid plates. NOTE 1For rigid or brittle thermal insulation materials it c

NOTE 2More information of the mode of failure will be available, if the load/displacement curve is measured during the test. 8 Calculation and expression of results 8.1 Tensile bond strength Calculate the tensile bond stre
