UNE-EN ISO 2361:2026

This document specifies the method for non-destructive thickness measurement via the magnetic type of

electrodeposited nickel coatings, also called e-nickel , on magnetic or non-magnetic substrates.

It can be that the method is not applicable to autocatalytic (electroless) nickel coatings depending on their

chemical composition since this coating is often non-magnetic.

For the purposes of this document, two types of substrates are distinguished:

a) nickel coatings on magnetic substrates (type A coatings).

b) nickel coatings on non-magnetic substrates (type B coatings).

Not all instruments are applicable to both types of coating.

The effective measuring ranges of instruments using the principle of magnetic attraction are up to 50 ¼m

for type A coatings, and up to 25 ¼m for type B coatings.

For instruments using the principle of reluctance, the effective ranges are much greater, up to 1 mm or even

more. This method is applicable for both types of coatings.
