with a template, the thickness of the uncoated specimen, then that of the coated specimen on several defined points in order to verify the even distribution of the dry film lubricant Between the two measurements apply the dry lubricant to one or both faces of the specimens 4.2 Cylindrical specimens Measure the diameter of the uncoated test specimen, then that of the coated specimen on several defined points in order to verify the even distribution of the dry film lubricant on the entire surface Between the two measurements apply the dry lubricant over the whole surface of the test specimens in the same manner as on the parts Test report It shall include the following: — reference to this standard; — designation to EN 3021; — number and position of the measuring points; — values obtained before and after the application of the dry lubricant Unless otherwise stated in the other test methods, the specimens are in aluminium alloy EN 2091, about 75 mm × 150 mm × 0,6 mm; they can be anodized to EN 2101 (with sealing) 3.2 Cylindrical specimens for inspection of process When the thickness cannot be measured on the parts, use a comparison test specimen consisting of a cylinder of the same material as the parts concerned, 80 mm in length and mm, 10 mm or 20 mm in diameter, the nearest to that of the concerned parts 1) Published as AECMA Standard at the date of publication 2) In
