mittepurustava kontrolli meetod, mille korral magnetpulberkatsel kasutatakse hälvingute ilmutamiseks kontrastvärvaineid ja ferromagnetilisi metallipulbreid, nt raudoksiidi (vt magnetpulberkontrastvärvkatse; vrd magnetfluorestsentspulberkatsetus), inspection for flaws with magnetic particles coated with contrast color to increase the visibility of results (see: magnetic particles contrast color test; compare: magnetic fluorescent particles testing)
