BRIEF HiISTORY
The IS0 Recommendation R 166, Drift Expanding 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.).
At the fourth meeting of the Technical Committee, held in Stockholm, in June 1955,
a draft proposal concerning a drift expanding 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 and 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 a 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 considera-
tion 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 ISO/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. 289) was distributed to all
the IS0 Member Bodies and was approved by the following Member Bodies:
Australia Germ an y Norway
Austria Greece Poland
Hungary Portugal
Belgium
Bulgaria India Romania
Burma Israel Spain
Chile Italy Sweden
Switzerland
Czechoslovakia Japan
Denmark Mexico United Kingdom
Finland Netherlands U.S.S.R.
France New Zealand
No Member Body opposed the approval of the Draft.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0
Council, which decided, in November 1960, to accept it as an IS0 RECOMMENDATION.
