35、before testing. They should be prepared according prescribed production conditions and conditioned at standard atmospheric conditions for at least 3 weeks. However if the samples are prepared within 3 weeks before testing, artificial aging in an oven at 40C during 3 x 24 hours is required. The sampl

37、ing and printings. For this method, preparation is done using a knife is used to cut gridlines over the area to be tested. The gridlines should be approximately 2mm spaced. b) Non-destructive test This test is intended for incoming inspections of batches of products with coatings and printings. Test

38、 Method (for both destructive and non-destructive) Press the self-adhesive tape with a length of about 5 cm firmly onto the sample, and remove it immediately with a jerk at an angle which is as close as possible to 60 to the surface. Corners and sharp edges have to be included in this test. 2.12.2.2

39、 Resistance to Ethanol Test method The coating is rubbed in groups of 10 or 25 rubbing cycles (one cycle = one complete to and from movement) with the hand tool with an average speed of 2 m/min. In the case that more than 25 cycles are required, the felt has to be soaked after each 25th cycle with E

40、thanol by means of a diffuser and the test should be continued immediately. After the last test cycle rests of the Ethanol has to be wiped off immediately from the tested surface with a soft cloth. (See figure) Requirement: Rcs3 = 2x25 cycles 2-72.12.2.3 Resistance to Dry Abrasion Test method A fixe

41、d load of 2.5 N is used for this method. The specific pressure depends on the size of the area to be tested.

42、ing material type A-VFN, thickness 6.35mm). Requirement: Rda2 = 175Rev 2.12.2.4 Scratch Resistance (Scr) Test method: Test Roller used: Steel Tester Position: Tester should be placed vertically with both rubber wheels on the test substrate Average Speed: Very slow (2 m/min) Test Pattern: 2 perpendicular to each other Number of Stroke: 10cm (centre 6cm for assessment) Mutual Distance between strokes: approx 1cm Load Applied: 10N 2-8
