26、s the procedure for determining the behaviour of an organic coating on a metallic substrate when submitted to accelerated ageing by heating at a defined temperature for a defined period of time. It is not possible to test heat resistance in such a way as to control all possible conditions of use. Th
27、e aim of this test is therefore to furnish the basic test method for the effect of heat. Special applications might require that properties other than those mentioned in this Part of EN 13523 be checked. The test(s) to be done should then be agreed between the interested parties. 2 Normative referen

31、the purposes of this document, the terms and definitions given in EN 13523-0:2014 apply. 4 Principle A test specimen is subjected to an elevated temperature during a defined period of time. Certain physical properties of the test specimen are then compared to those of a reference specimen which has
32、been kept during the same period of time in ambient conditions of temperature. 5 Apparatus and materials 5.1 Air circulation oven, capable of being maintained at the chosen test temperature to 5 % (in C). 5.2 Apparatus as described in EN 13523-2, EN 13523-3 and EN 13523-7. 5.3 Transparent pressure-s
33、ensitive adhesive tape, 25 mm wide, with an adhesion strength of (10 1) N per 25 mm width when tested in accordance with EN 60454-2. DIN EN 13523-13:2014-08 EN 13523-13:2014 (E) 6 6 Sampling See EN 13523-0. 7 Test specimens See EN 13523-0. Two sets of specimens shall be taken: one set for the ageing
34、 tests and one set as reference specimens. Test and reference specimens shall be taken from the same precoated sheet of coil coated metal in order to ensure a precise assessment of the property being evaluated. The number and size of all specimens shall be such that all required tests can be carried
35、 out. See 8.1.1 and 8.3.1 respectively. 8 Procedure 8.1 Procedure using flat specimens 8.1.1 Select two specimens for each test. 8.1.2 Place one specimen, the reference specimen, in the ambient storage conditions. For more accurate tests, as required for instance in case of dispute, the ambient temp
36、erature shall be (23 2) C and the relative humidity (50 5) %, in accordance with EN 23270. 8.1.3 Subject the other specimen, the test specimen, to accelerated ageing in the air circulation oven (5.1) at the specified or agreed test temperature and for the specified or agreed period of time. 8.1.4 Af
37、ter the specified or agreed period of time remove the test specimen from the oven and condition it for at least 16 h under conditions as specified in 8.1.2. 8.1.5 Measure the gloss and colour of both the reference specimen and the aged test specimen, using the same apparatus and following the proced
38、ures described in EN 13523-2 and EN 13523-3 respectively. Calculate the gloss and colour differences. 8.2 Procedure using specimens that are to be aged after bending 8.2.1 If not otherwise agreed, select and bend specimens as described in EN 13523-7, i.e. by using the minimum bending radius that the
39、 material can tolerate without cracking being visible at 10 magnification. Assuming that Ta= a, where a represents the minimum radius and t the thickness of the substrate, prepare two sets of five specimens and bend them according to the following radii: Ta= a Tb= a + 0,5 t Tc= a + 1,0 t Td= a + 1,5
40、 t Te= a + 2,0 t Alternatively, bend the specimens using the conical wedge mandrel specified in EN 13523-7:2014, 5.1.2. 8.2.2 Place one set of specimens, the reference specimens, in the ambient storage conditions. For more accurate tests, as required for instance in case of dispute, the ambient temp
41、erature shall be (23 2) C and the relative humidity (50 5) %, in accordance with EN 23270. DIN EN 13523-13:2014-08 EN 13523-13:2014 (E) 7 8.2.3 Subject the second set of specimens, the test specimens, to accelerated ageing in the air circulation oven (5.1) at the specified or agreed test temperature
42、 and for the specified or agreed period of time. 8.2.4 After the specified or agreed period of time remove the test specimens from the oven and condition them for at least 16 h under conditions as specified in 8.2.2. 8.2.5 Assess the reference specimens for cracking which might have occurred during
43、natural ageing, and if specified measure loss of adhesion using the adhesive tape (5.3). 8.2.6 Assess the test specimens for cracking, and if specified measure loss of adhesion using the adhesive tape (5.3). 8.3 Procedure using specimens that are to be bent after ageing 8.3.1 Select and age five fla
44、t specimens at the specified or agreed test temperature and for the specified or agreed period of time. 8.3.2 Bend the reference specimens using the procedure described in 8.2.1 and place them for at least 16 h in ambient storage conditions as described in 8.2.2. 8.3.3 Bend the aged test specimens t
45、o the same radii as determined in 8.2.1. 8.3.4 Assess both the reference specimens and the test specimens as described in 8.2.5 and 8.2.6 respectively. 9 Expression of results Express the results as indicated in Table 1.
