BS EN 13523-13:2014EN 13523-13:2014 (E) 5 1 Scope This Part of EN 13523 specifies 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 per

23、iod of time. It is not possible to test heat resistance in such a way as to control all possible conditions of use. The 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

24、 EN 13523 be checked. The test(s) to be done should then be agreed between the interested parties. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

28、f time. Certain physical properties of the test specimen are then compared to those of a reference specimen which has 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 temp

29、erature to 5 % (in C).5.2 Apparatus as described in EN 13523-2, EN 13523-3 and EN 13523-7. 5.3 Transparent pressure-sensitive 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.

30、ng See EN 13523-0. 7 Test specimens See EN 13523-0. Two sets of specimens shall be taken: one set for the ageing 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 pro

31、perty being evaluated. The number and size of all specimens shall be such that all required tests can be carried 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 am

32、bient storage conditions. For more accurate tests, as required for instance in case of dispute, the ambient temperature 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

33、 oven (5.1) at the specified or agreed test temperature and for the specified or agreed period of time. 8.1.4 After 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 col

34、our of both the reference specimen and the aged test specimen, using the same apparatus and following the procedures 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

35、 agreed, select and bend specimens as described in EN 13523-7, i.e. by using the minimum bending radius that the 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

36、 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 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 am

37、bient storage conditions. For more accurate tests, as required for instance in case of dispute, the ambient temperature shall be (23 2) C and the relative humidity (50 5) %, in accordance with EN 23270. BS EN 13523-13:2014EN 13523-13:2014 (E) 7 8.2.3 Subject the second set of specimens, the test spe

38、cimens, 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. 8.2.4 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

39、 as specified in 8.2.2. 8.2.5 Assess the reference specimens for cracking which might have occurred during 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 adhesi

40、ve tape (5.3). 8.3 Procedure using specimens that are to be bent after ageing 8.3.1 Select and age five flat 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

41、for at least 16 h in ambient storage conditions as described in 8.2.2. 8.3.3 Bend the aged test specimens to 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 resul
