1 SCOPE
1.1 This standard describes the macroscopic methods used for assessing the content of non-metallic inclusions in wrought steel products.
1.2 Macroscopic methods are those dealing with non-metallic inclusions visible to the naked eye or with the aid of a magnifying glass with a magnification of not more than 10 ×. Only inclusions equal to or greater than 1 mm long are taken into consideration.
1.3 The methods applied and defined in this standard are:
a) Blue fracture test method;
b) Step machined test method; and
c) Magnetic particle inspection method.
