Amendments

In comparison with DIN 17172, May 1978 edition, the following amendments have been made.

a) Steel grades for quenching and tempering, as well as grades of high strength have been included.

b) Lower phosphorus and sulfur contents have been specified.

c) Minimum values of tensile strength and a range for the yield strength have been specified.

d) The requirements for the impact strength have been changed.

e) Tolerances on diameter and wall thickness have been changed.

f) Further tests (drop weight tear test, metallographic examination, hardness test, non-destructive tests) have been included.

g) Details of the hydrostatic test have been changed.

Foreword

This European Standard 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of an identical text or by endorsement, at the latest by December 1996, and conflicting national standards shall be withdrawn at the latest by December 1996.

The differences between EN 10208-2 and ISO 3183-2 [1] are mainly restricted to the following:

• normative references (see clause 2);
• this European Standard uses steel numbers in accordance with EN 10027-2 (see table 1);
• basis of the calculation of hydrostatic test pressure (minimum wall thickness; ISO 3183-2 offers the use of the specified wall thickness by agreement);
• this European Standard uses the standardized code numbers and terms of EURONORM 168 for the structure and the content of inspection documents.

According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom.
