Publication date:   Aug 30, 2001

Scope

This draft European prestandard defines a method of microscopic nonmetallic inclusion assessment using picture charts. The method does not apply to inclusions of length less than 3 microm or smaller than 2 microm width. Defined by a product standard or an agreement between the involved parties for certain special products inclusions with a width below 2 microm can only be evaluated according their length.
