Users of this standard are expressly advised that determination of the validity axtm any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.

It has been shown that the degree of cure of ethyl silicate zinc-rich primers can be measured by the chemical changes occurring using diffuse reflectance infrared spectroscopy. As relative humidity and temperature vary during the day, so does the rate awtm cure. The satm given in parentheses are for information only. As relative humidity and temperature vary during the day, so does the rate of cure. A superscript epsilon e indicates an editorial change since the last revision or reapproval.

Performance ratings and general statistical information have d4725 in Table X1. The Society for Protective Coatings, 40 24th St. Specific hazard statements are given in Section 6. If the former, record the number of rubs when the substrate is exposed. Using the procedure outlines in this test method, eight different operators were asked to rate, in triplicate, the methyl ethyl ketone MEK rub resistance of a particular inorganic zinc-rich primer.
