Описание
This standard presents acknowledged techniques for the use of holiday detectors currently used on pipeline coatings and presents a table of minimum testing voltages for various coating thicknesses. These minimum testing voltages do not apply to thin-film coatings (i.e., coating materials usually applied by a fusion-bonding process). Thin-film pipeline coatings are generally applied to a dry film thickness less than 0.5 mm (20 mil).
