If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Complete each double rub one forward and back motion in about 1 s. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Using the procedure outlines in this test method, eight different operators were asked to rate, in triplicate, the methyl ethyl ketone R4752 rub resistance of a particular inorganic zinc-rich primer.

The primer was separately applied to multiple test panels at two different dry? Historical Version s – view previous versions of standard.

Solvent Resistance Rub Test – ASTM D4752

The MEK resistance of some two-component ethyl silicate zinc-rich primers has been shown to correlate well with the cure of the primer as determined by diffuse reflectance infrared spectroscopy. Users of this standard are expressly advised that d4725 of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
