Foreword
This document (EN 10216-3:2002) has been prepared by Technical Committee EC/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of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002.
This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s).
For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.
Other Parts of EN 10216 are:
| Part 1: | Non-alloy steel tubes with specified room temperature properties |
| Part 2: | Non-alloy and alloy steel tubes with specified elevated temperature properties |
| Part 4: | Non-alloy and alloy steel tubes with specified low temperature properties |
| Part 5: | Stainless steel tubes |
Another European Standard series covering tubes for pressure purposes is:
| EN 10217: | Welded steel tubes for pressure purposes |
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
