European foreword

This document (EN 12680‑1:2025) has been prepared by Technical Committee CEN/TC 190 “Foundry technology”, the secretariat of which is held by DIN.

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of an identical text or by endorsement, at the latest by May 2026, and conflicting national standards shall be withdrawn at the latest by May 2026.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights.

This document supersedes EN 12680‑1:2003.

Annex C, Table C.1 provides details of significant technical changes between EN 12680‑1:2025 and EN 12680‑1:2003.

Within its programme of work, Technical Committee CEN/TC 190 requested CEN/TC 190/WG 10 “Testing for inner discontinuities” to prepare the following standard:

This is one of four European Standards for ultrasonic testing. The other standards are:

EN 12680‑2, Founding — Ultrasonic testing — Part 2: Steel castings for highly stressed components.
EN 12680‑3, Founding — Ultrasonic testing — Part 3: Spheroidal graphite cast iron castings.
EN 12680‑4, Founding — Ultrasonic testing — Part 4: Phased array ultrasonic testing of steel castings

Annex A and Annex B are informative.

Any feedback and questions on this document should be directed to the users’ national standards body. A complete listing of these bodies can be found on the CEN website.

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United Kingdom.

1 Scope

This document specifies the requirements for the ultrasonic testing of steel castings (with ferritic structure) for general purposes and the methods for determining internal discontinuities by the pulse-echo technique.

This document is applicable to the ultrasonic testing of steel castings which have usually received a grain refining heat treatment and which have wall thicknesses up to and including 600 mm.

For greater wall thicknesses, special agreements are applicable with respect to test procedure and recording levels.

This document does not apply to austenitic steels and joint welds. For highly stressed components EN 12680‑2 is applicable.
