Using the procedure outlines in this test method, eight different operators were asked to rate, in triplicate, xstm methyl ethyl ketone MEK rub resistance of a particular inorganic zinc-rich primer. A number in parentheses indicates the year of last reapproval. 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 re? Adtm Version s – view previous versions of standard.

A certain minimum degree of cure is necessary prior to topcoating. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are asgm their own responsibility.
Rate the results in accordance with Table 1. 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.
The following observations were made through this analysis: The primer was separately applied to multiple test panels at two different dry? It is the responsibility of the user of this standard to establish appropriate safety asgm health practices and asgm the applicability of regulatory limitations prior to use. Performance ratings and general statistical information have been in Table X1. If the former, record the number of rubs when the substrate is exposed.

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. Separate test panels corresponding to each coating thickness category were scored after a 6-h cure period and a h cure period. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Precision and Bias 8. The values given in parentheses are for information only. Complete each double rub one forward and back motion in about 1 s.
