Salt spray cabinet, in accordance with ISO 7253:1996 and ISO 9227:1990, calibrated in accordance with ISO7253:1996, annex C.5.2
Test solution, as specified in 5.2.1 or 5.2.2 respectively.5.2.1
For neutral salt spray fog, the test solution shall be prepared by dissolving sodium chloride in water of atleast grade 3 purity as defined in EN ISO 3696:1995 to produce a concentration of (50 ± 5) g/l. The sodium chlorideshall be white, of minimum assay 99,6 % (by mass), and substantially free from copper and nickel; it shall containnot more than 0,1 % (by mass) of sodium iodide. If the pH of the solution is outside the range 6,0 to 7,0, thepresence of undesirable impurities in the salt or the water or both shall be investigated. The pH of the test solutionshall be adjusted so that the pH of sprayed solution collected within the salt spray cabinet (5.1) is between 6,5 and7,2. Any necessary adjustment to the pH shall be made by additions of solutions of either hydrochloric acid orsodium bicarbonate of analytical grade.5.2.2
For acetic acid salt spray (fog), add a sufficient amount of glacial acetic acid to the sodium chloride solution(5.2.1) to ensure that the pH of sprayed solution collected within the salt spray cabinet (5.1) is between 3,1 and 3,3.If the pH of the solution initially prepared is 3,0 to 3,1, the pH of the sprayed solution is likely to be within thespecified limits.NOTEUnder normal conditions, the level of glacial acetic acid required is approximately 0,3 % (by mass).5.3
Cutting tool, with a hard metal tip (according to Clemen). The scratch shall have an upwards-broadeningcross section which shows a width of approx. 1 mm of the substrate.NOTEIf the substrate is zinc- or zinc-alloy coated steel, the scratch is then to the zinc coating, and not further, to the steel.5.4
Transparent pressure-sensitive adhesive tape, 25 mm wide, with an adhesion strength of (10 ± 1) N per25 mm width when tested in accordance with IEC 60454-2.5.5
Sharp drill bit, of diameter approximately 5 mm for creating the hole.5.6
Appropriate pressing (bending) apparatus, as described in prEN 13523-19, 5.2, or EN 13523-7:2001, 5.1.2.6 SamplingSee EN 13523-0:2001.SIST EN 13523-8:2003
