Specifies a method for performing the etch inspection of metallic materials and components. Also describes some of the most widely accepted etching solutions currently being used.

1.1.1 This British Standard describes a method for carrying out etch inspection of metallic materials and components and describes some of the widely accepted etching solutions currently in use.

1.1.2 The materials covered by the standard are grouped as follows :

Ferrous metals

Plain carbon, medium and low alloy steels.
High alloy (corrosion and heat-resisting) steels.

Non-ferrous metals

Copper alloys.
Aluminium alloys.
Magnesium alloys.
Titanium alloys.
Nickel and cobalt base alloys.
