Polish the unnumbered side of th
44、e test panels to a surface finish of 380 130 nanometers using a 240-grit aluminum oxide or silicon carbide abrasive, with either cloth or paper backing. Do not use “wet or dry”, waterproof, or iron oxide abrasive. After abrading, clean the panels immediately, using the following procedure: a. Wipe t
45、he abraded faces of the panels with clean surgical gauze to remove superficial dust.

Remove the remaining residue and contamination by holding the panels in a rack at 20 degrees from
46、 the vertical and spraying downward with naphtha. Flush the surfaces progressively downward, spraying first the test surfaces, then the backs of the panels and finally the test surfaces again. c. Heat the panels in boiling naphtha for 5 to 10 minutes. d. Rinse the panels in boiling anhydrous methano
47、l defined by ASTM D1152. e. Inspect the panels carefully under a bright light to determine if any surface residues remain. f. Desiccate the panels at 25 3C and place in use within 2 hours.
