European foreword
This document (prEN 10216-2:2023) has been prepared by Technical Committee CEN/TC 459 “ECISS –
European Committee for Iron and Steel Standardization” , the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 10216-2:2013+A1:2020.
For the list of the most significant technical changes that were made in prEN 10216-2:2023, see Annex B.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of
EU Directive(s) / Regulation(s).
For relationship with EU Directive(s) / Regulation(s), see informative Annex ZA, which is an integral part
of this document.
EN 10216 consists of the following parts, under the general title "Seamless steel tubes for pressure
purposes – Technical delivery conditions":
— Part 1: Non-alloy steel tubes with specified room temperature properties
— Part 2: Non-alloy and alloy steel tubes with specified elevated temperature properties (the present
document)
— 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 series, Welded steel tubes for pressure purposes – Technical delivery conditions

Through its sub-committee SC 10 “Steel tubes, and iron and steel fittings” (secretariat: UNI).

1 Scope
This document 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.
This Part of EN 10216 can also be applied for tubes of non-circular cross section; necessary modification
will be
