FIELD: nondestructive inspection.
SUBSTANCE: color chemical reaction between penetrant and developer is used for defect indication. Penetrant has surface-active substance (SAS), ethyl alcohol, water, boric acid. Developer has glycerin, kaolin, SAS, ethyl alcohol, bromine-thymol blue indicator and PH regulator for achieving initial blue-green color.
EFFECT: improved reliability.
