What is ISO 2361 - Electrodeposited nickel coating thickness about?  

ISO 2361 is an International Standard that 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 ISO 2361 , two types of nickel coating are distinguished:   ...
