24、75mm 150mm 3mm. An apparatus suitable for the measurement of the coating thickness and a salt spray chamber to ISO9227. 4 Procedure Degrease the specimens and dry abrasive blast both surfaces and edges of the specimens with clean dry alumina of1254m grain size. Phosphate the specimens according to E
25、N2793:zinc phosphate to a mass per unit area ofnot less than7g/m 2or manganese phosphate to amass per unit area of not less than4g/m 2 . Measure the thickness of the specimen taking care not to damage the phosphating. Apply the dry lubricant to the surfaces and edges in accordance with EN2491. After
26、 curing, to avoid the edge effect, seal the edges on10mm width with a suitable sealing compound. Verify according to EN3032 that the thickness meets the requirements of EN3021. Test the specimens according to ISO9227. After an exposure for96h, remove them and rinse them in deionized water to remove
27、salt residues. 5 Expression of results Examine the specimens visually, note the number and size of any rust spots and the number of blisters on each specimen. 6 Test report It shall include the following: reference to this standard; film designation to EN3021; application method to EN2491; curing co
