AS 1855-2008 specifies methods by which transverse (circumferential) tensile properties of a section of a round steel pipe (tube) may be determined or proven to be above specified values.

This Standard specifies methods by which transverse (circumferential) tensile properties of a section of a round steel pipe (tube) may be determined or proven to be above specified values.
The methods permit the use of both short-length and long-length pipe test pieces, but they preclude spirally welded pipe
