I believe you are referring to Method B within ASTM D3359 [link by ed. to spec at TechStreet] . If so, the spacing between the cuts varies with the dry film thickness of the coating. For coatings with dry film thickness of up to and including 2 mils, the spacing is 1 mm apart, with eleven cuts total (unless there is another agreement). For coatings between 2-5 mils, the spacing is 2 mm and six cuts. For thicker coatings, Method A is recommended (an "X" cut procedure).Roy Nuss

>From Paragraph 12.2.1- "For coatings having a dry film thickness up to and including 2.0 mils (50 microns) space the cuts 1 mm apart and make eleven cuts unless otherwise agreed upon."
>From Paragraph 12.2.2- "For coatings having a dry film thickness between 2.0 mils (50 microns) and 5.0 mils (125 microns) space the cuts 2 mm apart and make six cuts. For films thicker than 5.0 mils use Test Method A (X-Cut Tape Test)."
AFTER FOLLOWING THE PROCEDURES FROM ASTM D3359 B, WHAT TYPE OF TAPE DO I NEED TO USE AND HOW MANY RUBS DO I HAVE TO TAKE AND AT WHAT ANGLE DO I NEED TO PULL THE TAPE?CESAR H. MARISCAL
