适用范围：This International Standard specifies the method of using coating thickness instruments of the magnetic type for non-destructive measurements of the thickness of electrodeposited nickel coatings on magnetic or non-magnetic substrates.The method may not be applicable to autocatalytic (electroless) nickel coatings depending on their chemical composition.For the purposes of this International Standard, two types of nickel coating are distinguished :a) nickel coatings on magnetic substrates (type A coatings);b) nickel coatings on non-magnetic substrates (type B coatings).It should not be assumed that all instruments are applicable to both types of coating.The effective measuring ranges of instruments using the prin-ciple of magnetic attraction are up to 50 (jm for type A coatings, and up to 25 u.m for type B coatings.For instruments using the principle of reluctance, the effective ranges are much greater and measurements up to 1 mm, or more, can be made on both types of coating.
