34、ined by means of a steel ball falling onto the surface of the kit. The energy level and corresponding dropping height is selected from Table 1. Any damages occurring are visibly assessed (e.g. the reinforcement has become visible from the external surface, the finishing coat or the rendering system

35、has visibly delaminated or been perforated) and cracks widths are measured. 5 Test apparatus 5.1 General For the test a steel ball is dropped from a specified height onto the surface of the test specimen (see Table 1). A second impact (rebound) by the ball shall be avoided. 1To be published. Stage a

BS EN 13497:2018EN 13497:2018 (E) 5 5.2 Steel ball requirements Balls made of cutlery grade steel, AISI/SE Type 440 C and grade G100 according to ISO 3290-1 with the weights and nominal diameters given in Table 1. 5.3 Crack measuring gauge For measurement

37、of the width of any cracks formed as a result of the impact of the steel ball onto the surface of the test specimen. The gauge shall be capable measuring from 0,1 mm and be graduated in steps of 0,05 mm. 5.4 Specimen support The support itself shall be flat, not bend, deform or absorb impact energy

38、during the test, e.g. concrete support, in order not to influence the test result. The test specimen shall not move or bump during the test. NOTE 1 Larger specimen tends to show less movement than smaller specimen. NOTE 2 The specimen might be fixed, clamped or glued to the support so that contact b

39、etween them is maintained during the test. 5.5 Optional tube to control descent of steel ball A vertical tube manufactured from a metal or rigid plastic can be used for this purpose with an inner diameter at least 2 mm larger than the steel ball diameter. The walls of the tube should preferably incl

40、ude regular perforated holes to prevent air within the tube becoming compressed due to the velocity of the ball during its descent and thereby acting as a “resistance cushion” to the impact of the ball with the specimen surface.

43、. It consists of the thermal insulation product with the rendering system. It shall be prepared according to the system holders instructions. 6.2 Sealing and conditioning of test specimens Sealing and conditioning of test specimen shall be according to procedure 1 or procedure 2 as follows: Procedur

44、e 1: The reverse side and the edges of the test specimen shall be sealed, if exposure to water occurs. Condition the test specimens after preparation as follows: (23 2) C and (50 5) % r. H. for at least 28 days; Conditioning according to EN 16383 test cycles; Drying for at least 7 days at (23 2) C a

48、be placed on a support according to 5.4. The steel ball is dropped from the specified height onto the surface of the test specimen, as determined in Table 1, see Figure 2. For each energy level chosen, five separate impacts are performed at different positions of the test specimen. The minimum dista

49、nce between any impact position and the specimen edges shall be at least 100 mm. The minimum distance between any impact position and the insulation board edges shall be at least 100 mm, i.e. no impact on a joint between insulation boards if more than one board is used to prepare the test specimen. The centre to centre distance between any two impacts shall be at least 100 mm. In case of possible rebound, the steel ball shall be caught or diverted away to avoid a second impact. If a perf
