Elcometer supplies a wide range of Leneta Test Charts
, from plain white to those having different patterns of black and white. Made from naturally bright, non-fluorescent white paper, these charts contain no optical brighteners that can affect instrumental color measurements.
Leneta Test Charts are the market standard in today’s coatings industry. Foil Card substrates of steel, aluminum, glass and plastic are also available. Leneta Test Charts are available in boxes & cases.
Charts can be used with the Elcometer 4340 Motorised Film Applicator
Scrub Test Panels
In a typical scrub test, the coating is applied to the Leneta Scrub Test Panel at a specified film thickness, allowed to dry and then subjected to scrubbing with a straight-line scrub tester.
When used in accordance with ASTM D2486, Method A, a 10mil shim is inserted under the panel to accelerate failure and thereby reduce testing time. The scrub resistance is the number of scrub cycles required to remove the coating to a specified end point.
Alternatively, the loss in weight is determined after a specified number of scrub resistance cycles, with calculation of equivalent loss in film thickness.
These Scrub Test Panels are ideal for use with the Elcometer 1720 Washability & Abrasion Testers
