8、es). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and
9、non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, P
10、art 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casti
11、ng a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 29804 was prepared by Technical Committee ISO/TC 163, Thermal performance and energy u
12、se in the built environment, Subcommittee SC 1, Test and measurement methods. ISO 29804 is based on EN 13494:2002 prepared by Technical Committee CEN/TC 88 Thermal insulating materials and products.

ISO 29804:2009(E) 2 ISO 2009 All rights reserved4 Principle The tensi
30、le bond strength of the adhesive and of the base coat to the thermal insulation material is 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 glued to the test area of the adhesive or base coat. 5 Apparatu
31、s 5.1 Glue, 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 adhesive and shall not influence the results. 5.2 Rigid plates (e.g. plywood of thickne
32、ss 20 mm or steel plates of thickness 5 mm), of the dimensions of (200 2) mm (200 2) mm. The rigid plates with the dimensions of (50 2) mm (50 2) mm may be used for direct measurements on the rig. The mechanical stability or the rigid plates shall not influence the test results. They shall have a ce
33、ntral fitting 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 driv
34、en saw (e.g. 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, appropriate for the range of force and displacement involved, capable of having a con
35、stant 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 ISO 29765). For measurements directly on the rig, portable devices may be used, with a precisio
36、n of 10 %. In this case, the size of the test specimen shall be 50 mm 50 mm for tractions higher than 50 kPa. For values lower than 20 kPa, direct measurement on the rig shall not be carried out. A precise traction machine shall be used (with a precision of 1 %) with samples of 200 mm 200 mm. 6 Test
37、 specimens 6.1 Preparation of the samples The adhesive, or base coat with the reinforcement, is applied in accordance with the manufacturers instructions to the surface of the thermal insulation material having minimum dimensions of 500 mm 1 000 mm 10 mm. The samples shall not include mechanical fix
38、ings. 6.2 Conditioning of the samples The conditioning of the samples shall be carried out as specified in the relevant ETICS product standard. NOTE In the absence of a product standard for ETICS or any other European technical specification, the conditioning procedure can be agreed on between the p
39、arties. 6.3 Preparation and number of test specimens Cut three square-shaped 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 r
40、ounded to the nearest millimetre. ISO 29804:2009(E) ISO 2009 All rights reserved 3Apply a thin layer of glue to both surfaces of 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 to the test
41、 specimen ensuring that the centre of the rigid plates coincides with the centre square-shaped test specimen. Take care that the glue does not run down the sides of the test specimen. Allow the glue to harden in accordance with the manufacturers instructions. In tropical countries, different conditi
42、oning and testing conditions might be relevant. In this case, the conditions shall be (27 2) C and (65 5) % relative humidity and be stated clearly in the test report. 7 Procedure 7.1 Test conditions The test shall be carried out at (23 2) C and (50 5) % relative humidity. In tropical countries, dif
43、ferent conditioning and testing conditions might be relevant. In this case, the conditions shall be (27 2) C and (65 5) % relative humidity and be stated clearly in the test report. 7.2 Attachment of the test specimens to the tensile testing machine Attach the test specimen in the tensile testing ma
44、chine by means of the central fitting of the rigid plates. Figure 1 illustrates the attachment of the test specimen to the tensile testing machine.

45、ing machine 5 glue Figure 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 ISO 29765 until failure occurs. Apply the tensile load perpendicular to the test area through the rigid plates by means of the
46、 tensile testing machine. Increase the load with a constant crosshead speed adjusted to (10 1) mm/min. ISO 29804:2009(E) 4 ISO 2009 All rights reservedRecord 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 rigi
47、d plates. NOTE 1 For rigid or brittle thermal insulation materials, it can be better to make the measurement with a load controlled speed of 100 N/s. NOTE 2 Additional information on the mode of failure can be made available, if the load/displacement curve is measured during the test. 8 Calculation
48、and expression of results 8.1 Tensile bond strength Calculate the tensile bond strength, , in kilopascal, using Equation (1): F A = (1) where F is the tensile load at failure, in kilonewton; A is the cross-sectional area of the plate, in square metres; is the tensile bond strength, in kilopascal. Th
49、e results shall be rounded to the nearest 1 kPa. 8.2 Mode of failure Note which mode of failure occurs. Possible failures are: cohesive failure in the base coat or adhesive; adhesive failure between base coat or adhesive and the thermal insulation material; cohesive failure in the thermal insulation material; adhesive failure between base coat and reinforcement. 9 Accuracy of measurement NOTE It was not possible to inc
