BRIEF HISTORY
The IS0 Recommendation R 134, Non-Screwed Steel Tubes for General Purposes, was drawn up by
Technical Committee ISO/TC 5, Pipes and Fittings, the Secretariat of which is held by the Association
Suisse de Normalisation (SNV).
A fmt draft proposal entitled “IS0 Seamless Non-Screwed Tubes: Class N, General Purpose Tubes
(Commercial) ”, was submitted to the third plenary meeting of ISO/TC 5, held in Stockholm, in June 1955,
but was referred back to Sub-Committee ISO/TC 5/SC 1, Gas List Tubes and Other Steel Pipes, for further
consideration, in conjunction with the standardization of a series of outside diameters of steel tubes and
also steel tubes suitable for screwing in accordance with IS0 Recommendation R 7.
After having completed the consideration of a general series of outside diameters (see IS0 Recommend-
ation R 64) and also tubes which may be screwed (see IS0 Recommendation R 65), Sub-Committee
ISO/TC 5/SC 1 appointed a group of experts to prepare new proposals. These proposals enabled the
Secretariat of ISO/TC 5/SC 1 to establish a second new document, which was adopted by the Sub-
Committee during its seventh meeting, held in Amsterdam, in April 1957, as a second draft proposal. This
document was circulated to all the members of the Technical Committee and approved by a majority as
a Draft IS0 Recommendation.
On 22 August 1958, the Draft IS0 Recommendation (No. 225) was distributed to all the IS0 Member
Bodies and was approved, subject to some modifications, by the following Member Bodies:
Australia Hungary Pakistan
Belgium India Poland
Chile Israel Spain
Denmark Italy Sweden
Finland Japan Switzerland
France Netherlands United Kingdom
Germany Norway
One Member Body opposed the approval of the draft: U.S.S.R.
The Draft IS0 Recommendation was then submitted by correspondence to the IS0 Council, which
decided, in September 1959, to accept it as an IS0 RECOMMENDATION.
BRIEF HISTORY DEALING WITH THE  ND EDITION
As manufacturing techniques had developed, Sub-Committee ISO/TC 5/SC 1, at its meeting in Gleneagles
(Scotland) in 1960, considered that it might be necessary to undertake a revision of this Recommendation,
so as to insert therein the modifications specified in the table below (indicating the new values proposed to
replace the values struck out).

This proposal having been accepted by Technical Committee ISO/TC 5, a Draft Revision of IS0 Recom-
mendation R 134 was circulated in October 1961 to all the IS0 Member Bodies, and was approved by
21 Member Bodies.
Two Member Bodies opposed the approval of the Draft Revision:
