Scope

This Standard specifies a method for determining the ability of metallic tubes of circular cross-
section to undergo plastic deformation in drift expansion.
This Standard is intended for tubes having an outside diameter no greater than 150 mm (100
mm for light metals) and a thickness no greater than 10 mm although the range of the outside
diameter or the thickness for which this Standard is applicable may be more exactly specified
in the relevant product standard.

Summary	This standard specifies test methods for the determination flared circular cross -section metal pipe plastic deformation capacity. This standard applies to external diameter not exceeding 150 mm (non-ferrous metal pipe outside diameter of not more than l00 mm), wall thickness of not more than l0 mm metal tube. This standard applies to the range of metal pipe diameter and wall thickness can be specified in more detail in the relevant product standard.
