IS 10138 : 2010 : Macroscopic Methods For Determination Of Non-Metallic Inclusion Content In Wrought Steels

ICS 77.040.99; 77.080.20 MTD 22

Reaffirmed 2022

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.
