BRIEF HISTORY
The IS0 Recommendation R 167, Bend Test on Steel Tubes, was drawn up by
Technical Committee ISO/TC 17, Steel, the Secretariat of which is held by the British
Standards Institution (B.S.I.).
of the Technical Committee, held in Stockholm, in June 1955,
At the fourth meeting
a draft proposal concerning a bend test on steel tubes, was first submitted. It was, however,
suggested at that meeting that the drafts should be submitted to Technical Committee
ISO/TC 5, Pipes und Fittings, for comments, and that these comments, together with
those of the members of Technical Committee ISO/TC 17, should be considered by
Working Group No. 1 with a view to establish the revised draft proposal.
At the time of the fifth meeting of the Technical Committee, held in London, in
March 1957, this test, together with four others for steel tubes, was still under con-
sideration by Working Group No. 1.
At the sixth plenary meeting, held in Harrogate, in June 1958, a new draft proposal was
placed before Technical Committee lSO/TC 17 for consideration and, with one or two
minor editorial amendments, was accepted as suitable for circulation to the members of
the Technical Committee for postal approval.
As a result of that circulation, certain other minor amendments were made and a
revised draft was sent to the General Secretariat as a Draft IS0 Recommendation.
On 24 July 1959, the Draft IS0 Recommendation (No. 290) was distributed to all the
IS0 Member Bodies and was approved by the following Member Bodies:
