Part 1: Non-alloy steel tubes with specified room temperature properties English version of DIN EN 10216-1

DIN EN 10216-1

ICS 23.040.10; 77.140.75

Supersedes parts of DIN 1629 and DIN 1630, October 1984 editions.

European Standard EN 10216-1 : 2002 has the status of a DIN Standard.

A comma is used as the decimal marker.

National foreword

This standard has been prepared by ECISS/TC 29.

The responsible German body involved in the preparation of this standard was the Normenausschuss Eisen und Stahl (Steel and Iron Standards Committee), Technical Committee Rohre aus allgemeinen Baustählen oder Feinkornbaustählen.

This standard is to be used in conjunction with DIN EN 10208-1, DIN EN 10224 and DIN EN 10297-1, the last two standards still being at draft stage. Once these standards have become the status of full standards, DIN 1629 and DIN 1630 will be withdrawn.

It should also be noted that steel grade St 52 has been dropped, guideline values for the 0,2 % elevated temperature proof stress are now longer included and grade P195 is now specified.

DIN V 17006-100 is the standard corresponding to CEN Report CR 10260.

Amendments

Parts of DIN 1629 and DIN 1630, October 1984 editions, have been superseded by the specifications of EN 10216-1.

Previous editions

DIN 1629: 1929-08, 1932-09, 1984-10; DIN 1629-1: 1961-01; DIN 1629-3: 1961-01; DIN 1629-04: 1961-01; DIN 1630: 1984-10.
