25、r the repair and protection of concrete. This part is relevant only to surface protection systems, and specifies a method for determining the resistance of surface protection systems to high temperature shock. This test method is also suitable for testing the resistance of surface protection systems

ISO 4628-5, Paints and varnishes - Evaluation of degradation of paint coatings Designation of intensity, quantity and
30、size of common types of defect Part 4: Designation of degree of flaking. 3 Principle The principle of the test method consists of applying a layer of the surface protection system to a reference concrete slab (prepared according to EN 1766). After curing, the test specimen is subjected to a temperat
31、ure shock, which is achieved by applying hot asphalt or bitumen or chemicals. After the thermal load, visible defects are recorded and the adhesion of the surface protection system is determined by pull-off test (according to EN 1542). 4 Apparatus 4.1 Laboratory Maintained at the temperature of (21
32、? 2) C and a relative humidity of (60 ? 10) %. 4.2 Usual accessories to apply the coating material to the concrete substrate. 4.3 Two concrete slabs 400 mm x 400 mm x 50 mm Using a concrete MC (0,40) according to EN 1766 as substrate for the coating.

At its base th
34、e cylinder has a steel flange, 24 mm wide x 10 mm thick, with a 24 mm wide x 22 mm thick compressible, heat resistant sealing ring to suit. Just above the flange the cylinder is fitted with a suitable draining device to facilitate removal of the test liquid. The base of the apparatus consists of a 3
35、50 mm x 350 mm x 12 mm thick steel plate, with four clamps which are used to clamp the test panel between this plate and the sealing ring and flange of the cylinder. The top of the cylinder is fitted with an insulated lid, part of which can be removed to allow fast but safe. 4.5 Silicone oil as test
36、ing liquid at least 11 litres. NOTEOther hot chemicals can be used in accordance with the manufacturers instructions. 4.6 Hot plate 4.7 Stirrer with a speed of approx. 200 rpm 4.8 Thermometer or thermocouples to measure the temperature on the surface of the coating continually. 4.9 Diamond core dril
37、l equipment according to EN 1542 with a diamond tool, internal nominal diameter 50 mm. 4.10 Pull-off equipment for measuring the pull-off strength according to EN 1542. 5 Preparation of test specimens The application of the surface protection system to the two concrete substrate (4.3) shall be carri
38、ed out at standard climate conditions (4.1) or such alternative environments as may be specified for the intended use. Two test pieces (4.3) are required for each test, with one serving as a reference test piece. The side of the concrete slab specimens placed underneath during the casting shall be p
39、repared by grit-blasting in accordance with EN 1766, cured according to A.2.1 (dry conditioning) followed by preparation and application of the surface protection system, in accordance with manufacturers instructions. Cure the coating under test in a climate (21 ? 2) C and (60 ? 10) % R. H. in accor
40、dance with the manufacturers instructions. 6 Procedure All components are to be conditioned in the laboratory (4.1) for at least 24 h prior to assembly. The test piece is positioned onto the square base plate with the thermocouple or thermometer firmly fixed to the centre of the surface of the test
41、piece. The sealing ring and flanged cylinder are positioned over the test piece and clamped to the base plate. The test temperature shall be agreed between the interested parties. It should be selected in multiples of 10 C. To test the performance of a coating below a mastic asphalt coat, a temperat
42、ure of (250 ? 5) C is recommended.

43、 filling to a depth of (155 ? 5) mm. After 3 minutes a stirrer rotating at 200 rpm 50 mm above the test surface is switched on. (In the case of mastic asphalt the temperature on the surface of the test piece must rise to (150 ? 5) C within 7 minutes, and at the end of the test shall exceed 85 C). Th
44、e test shall last for 60 minutes and the temperature shall be monitored throughout that time. At completion of the test the oil is drained and the test panel is removed and blotted dry ready for examination. 7 Evaluation of results Examine the test piece for surface cracking (according to ISO 4628-4
45、), flaking (according to ISO 4628-5) or bubbling of a coating or de-bonding or any other obvious change. The bond strength of the coating is measured by pull-off test according to EN 1542 after at least 24 h of cooling down to room temperature. Before measuring pull- off strength the surface of the
46、coating is to be cleaned with a suitable solvent which will remove all traces of the test liquid but which will have no detrimental effect on the adhesion of the dolly to the surface of the test piece. For comparison purposes the pull-off strength of the reference test piece shall also be measured a
47、ccording to EN 1542. 8 Test report The test report shall at least include the following information: a) a reference to this test method standard; including the number and date of issue; b) name and address of the test laboratory; c) identification number and date of the test report; d) name and addr
48、ess of the manufacturer or supplier of the product(s); e) a description of the product or system under test and whether it is a single or multi-layer system and the thickness(es) of the layer(s); f) name and identification marks or batchnumber of the product(s); g) date of supply of the product; h)
49、date of preparation of the test specimen and any deviation from the prescribed method of preparation; i) conditions of storage of prepared specimens prior to test; j) date of test and details of the test equipment used; k) test temperature and the test liquid used; l) a description of any cracking, flaking, bubbling, spalling, de-bonding or any other change of the material under test; m) the test results (single and mean values) of the pull-off tests including individual for
