IS 7739 : Part 5 : 1976 Code of Practice for Preparation of Metallographic Specimens - Part 5 Iron and steel and their examination

1. Scope

1.1 This standard ( Part V) covers the polishing etching and examination of iron and steel.

1.2 For convenience, this standard is divided in two sections, namely:

a) Macroscopic examination - In which the study is made at low magnification ( usually 10 X or less).

b) Microscopic examinution - In which the study is made at comparatively high magnification and resolution.

1.3 A metallographic examination shall frequently include both a macroscopic and microscopic examination. However, there are many occasions on which either the macroscopic or microscopic study alone is sufficient to supply the desired information.
