Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
The MEK resistance of some twocomponent ethyl silicate zinc-rich primers has been shown to correlate well with the cure of the primer as determined by diffuse re? Originally approved in Precision and Bias 8. 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.
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 d4572 infrared spectroscopy. Practice D is the preferred method for organic coatings.
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 d472 The following observations were made through this analysis: Last previous edition approved in as D — TABLE 1 Scale for Resistance Rating Resistance Rating 5 aetm 3 2 1 0 Description No effect on surface; no zinc on cloth after 50 double rubs Burnished appearance in rubbed asgm slight amount of zinc on cloth after 50 double rubs Some marring and apparent depression of the?

Separate test panels corresponding to each coating thickness category were scored after a 6-h cure period and a h cure period.
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.
Rate the results in accordance with Table 1.
Complete each double rub one forward and back motion in about 1 s. As relative humidity and temperature vary during the day, so does the rate of cure.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every? A number in parentheses indicates the year of last reapproval.
