mittepurustava kontrolli meetod, mille korral magnetpulberkatsel kasutatakse hälvingute ilmutamiseks fluorestseeruvaid aineid ja ferromagnetilisi metallipulbreid, nt raudoksiidi (vrd magnetpulberkontrastvärvkatse), inspection for flaws with magnetic particles coated with fluorescent material to increase the visibility of results (compare: magnetic particle contrast color test)
