As relative humidity and temperature vary during the day, so does the rate of cure. Last previous edition approved in as D — The values given in parentheses are for information only.
The following observations were made through this analysis: Link to Active This link will always route to the current Active version of the standard. Specific hazard statements are given in Section 6. Reagents and Materials 5.
Originally approved in The Society for Protective Coatings, 40 24th St. Clean the surface with tap asm or dry cloth to remove loose material. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
A certain minimum degree of cure is necessary prior to topcoating. 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. Precision and Bias 8.
Use this area as the control to visually show the appearance of No Effect. Do not allow more than 10 s to elapse before proceeding to the next steps. Current edition approved Jan.

A certain minimum degree of cure is necessary prior to topcoating. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. 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?
