Scope

This Standard specifies the test principle, test equipment, test piece, test
procedure and test report of the bend test method for metallic tubes.
This Standard applies to the determination of the full-section bending plastic
deformation capacity of circular cross-section metallic tubes with an outer
diameter not greater than 65 mm. The outer diameter range of the applicable
metallic tubes of this Standard can be specified in more detail in the relevant
product standards.
NOTE: The bend test of the transverse strip test piece of metallic tubes is carried out according
to GB/T 232[1], to increase the original bending rate of the test piece.
