Foreword
This document (EN 10296-2:2005) has been prepared by Technical Committee ECISS/TC 29 “Steel tubes and
fittings for steel tubes”, the secretariat of which is held by UNI.
This European Standard shall be given the status of a national standard, either by publication of an identical text or
by endorsement, at the latest by June 2006, and conflicting national standards shall be withdrawn at the latest by
June 2006.
Another part of EN 10296 is:
— Part 1: Non-alloy and alloy steel tubes
Another European Standard series, covering seamless steel tubes for mechanical and general engineering
purposes, currently being prepared is:
— EN 10297: Seamless circular steel tubes for mechanical and general engineering purposes — Technical
delivery conditions.
Other series of European Standards being prepared in this area are prEN 10294 - hollow bars for machining and
EN 10305 - steel tubes for precision applications.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following

CEN takes no position concerning the evidence, validity and scope of these patent rights.
The holders of these patent rights have assured CEN that they are willing to negotiate licences, under reasonable
and non-discriminatory terms and conditions, with applicants throughout the world. In this respect, the statements
of the holders of these patent rights are registered with CEN. Information may be obtained from:
