10216-2:2002) 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of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002.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 3 : Alloy fine grain steel tubes 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. EN 10216-2:2002 (E) 4 1 SCOPE This Part of EN 10216 specifies the technical delivery conditions in two test categories for seamless tubes of circular cross section, with specified elevated temperature properties, made of non-alloy and alloy steel. NOTE This Part of EN 10216 may also be applied for tubes of non-circular cross section; necessary modification should be agreed a the time of enquiry and order. 2 NORMATIVE REFERENCES This European Standard incorporates by date or undated reference, provisions from other publications.
