EN 10228: Ultrasonic Testing of Forgings
European standard for ultrasonic testing of forged components.
The European Committee for Standardization (CEN) publishes EN standards that are adopted as national standards across the EU and EFTA.
EN standards underpin the Pressure Equipment Directive (2014/68/EU) and are mandatory for CE-marking in the EU; outside the EU they remain widely used as accepted technical references.
EN 10228 is invoked when the scope of work matches its title — ultrasonic testing of forgings — and when the contract or regulatory regime cites it as the controlling document. In power and nuclear work, the inspection plan is built directly off the standard's tables; an auditor will cite the paragraph that was followed (or the one that was missed) when writing a finding. Aerospace work treats the standard as a floor rather than a ceiling — most prime contractors layer their own internal procedures on top, with tighter acceptance criteria than the published code. In fabrication shops the standard is reproduced inside the written procedure book and referenced from every inspection report so that the auditor's paper trail leads back to the same paragraph the inspector worked from.

- Personnel qualification: examinations under EN 10228 must be performed by inspectors qualified and certified to a recognised scheme (typically ASNT SNT-TC-1A, CP-189, or ISO 9712 depending on jurisdiction), with documented training hours, vision tests, and a controlling written practice.
- Written procedure: every examination requires a written, controlled procedure that names the method, equipment, calibration steps, scanning pattern, and acceptance criteria — and is qualified before first use.
- Equipment verification: ultrasonic instruments must be verified against a calibration block (V1, V2, IIW, or job-specific reference) at intervals defined by the procedure — typically before use, every four hours of scanning, on operator change, and at end of shift.
- Acceptance criteria: indications are evaluated against the standard's tabulated limits (length, depth, alignment, frequency); any indication exceeding the criteria is recorded, dispositioned, and either repaired or evaluated for fitness-for-service.
- Documentation: examination reports must include enough information for a third party to reproduce the inspection — equipment serial numbers, calibration records, inspector ID, sketches of indications, and the controlling procedure revision.
EN standards are managed under CEN's revision cycle and are republished as the European harmonised version of an ISO document where one exists. Updates to EN 10228 flow into the harmonised standards list under the relevant EU directive (e.g. PED 2014/68/EU); compliance with the latest harmonised version provides a presumption of conformity with the directive's essential requirements.
An aerospace manufacturing line will reference EN 10228 on the inspection-traveler card for each component; the inspection is performed by NAS 410-qualified personnel, and any indication exceeding the standard's limits triggers a Material Review Board disposition before the part is released to assembly.
What does EN 10228 cover?
EN 10228 (Ultrasonic Testing of Forgings) is published by CEN. European standard for ultrasonic testing of forged components..
Is EN 10228 mandatory or voluntary?
EN 10228 is a consensus standard. It becomes mandatory when invoked by a contract, by another code that cites it (for example ASME Section V calling out an ASTM practice), or by a regulator that has adopted it into law in a specific jurisdiction.
Who is qualified to perform inspections under EN 10228?
Inspections under EN 10228 must be performed by personnel qualified and certified to a recognised NDT certification scheme — most commonly ASNT SNT-TC-1A or CP-189 in the United States, ISO 9712 in much of the rest of the world, and NAS 410 for aerospace work. The written practice that controls qualification must be in place before any examination is started.
Which other standards are commonly cited alongside EN 10228?
EN 10228 is most often cited together with the parent code that brings it into the contract — typically ASME Section V or VIII for U.S. pressure equipment, AWS D1.1 for structural welding, API 510/570/653 for in-service petroleum equipment, or the matching EN/ISO standard for European and international work.
