Non-destructive testing of steel forgings - Part 3: Ultrasonic testing of ferritic or martensitic steel forgings

This European Standard describes techniques to be used for the manual, pulse-echo, ultrasonic testing of forgings manufactured from ferritic and martensitic steel. Mechanized scanning techniques, such as immersion testing, may be used but should be agreed between the purchaser and supplier (see Clause 4).
This part of EN 10228 applies to four types of forgings, classified according to their shape and method of production. Types 1, 2 and 3 are essentially simple shapes. Type 4 covers complex shapes.
This part of EN 10228 does not apply to:
-   closed die forgings;
-   turbine rotor and generator forgings.
Ultrasonic testing of austenitic and austenitic-ferritic stainless steel forgings is the subject of EN 10228-4.

Zerstörungsfreie Prüfung von Schmiedestücken aus Stahl - Teil 3: Ultraschallprüfung von Schmiedestücken aus ferritischem oder martensitischem Stahl

La présente norme européenne décrit la méthode manuelle par réflexion d'ondes ultrasonores utilisée pour le contrôle par ultrasons des pièces forgées en aciers ferritique et martensitique. Les méthodes de balayage automatique telles que l'essai par immersion peuvent être également utilisées, mais il convient qu’elles fassent l'objet d'un accord entre l’acheteur et le fournisseur (voir article 4).
La présente partie de l'EN 10228 porte sur les pièces forgées, classées en quatre familles suivant leur forme et leur mode de forgeage. Les familles 1, 2, et 3 recouvrent essentiellement les formes simples. La famille 4 concerne les formes complexes.
La présente partie de l'EN 10228 ne s'applique pas :
      aux pièces estampées ;
      aux rotors de turbine et aux alternateurs.

Neporušitveno preskušanje jeklenih izkovkov - 3. del: Ultrazvočno preskušanje feritnih ali martenzitnih jeklenih izkovkov

Ta del standarda EN 10228 opisuje tehnike, ki se uporabljajo za ročno pulzno-odbojno ultrazvočno preskušanje izkovkov, izdelanih iz feritnega in martenzitnega jekla. Mehanizirane tehnike skeniranja, kot so preskusi s potopitvijo, se lahko uporabljajo, vendar naj bi se kupec in dobavitelj o tem predhodno strinjala (glej točko 4).
Ta del standarda EN 10228 se uporablja za štiri tipe izkovkov, ki so klasificirani glede na njihovo obliko in metodo izdelave. Tipi 1, 2 in 3 imajo preprosto obliko. Tip 4 zajema kompleksne oblike.
Ta del standarda EN 10228 se ne uporablja za:
– izkovke, proizvedene z zaprtimi kokilami,
– izkovke turbinskih rotorjev in generatorjev.
Ultrazvočno preskušanje izkovkov iz avstenitnega in feritno-avstenitnega nerjavnega jekla je predmet 4. dela standarda EN 10228.

Overview

EN 10228-3:2016 is the CEN European standard that specifies techniques for manual, pulse-echo ultrasonic testing (UT) of forgings made from ferritic or martensitic steels. It covers A-scan pulse-echo inspection methods, probe selection, calibration, sensitivity setting and scanning strategies for four forging shape types (Types 1–4, with Type 4 being complex shapes). The standard excludes closed-die forgings and turbine rotor/generator forgings and notes that mechanized or immersion scanning may be used only by agreement between purchaser and supplier.

Key topics and technical requirements

• Scope: Manual pulse-echo UT of ferritic/martensitic steel forgings; separate part (EN 10228-4) covers austenitic and duplex stainless forgings.
• Test procedure: UT shall be performed using a written procedure (product specification, bespoke procedure, or EN 10228-3 with application-specific details). Procedure content requirements are listed (forging description, equipment, calibration, scanning plan, acceptance criteria, test report).
• Personnel: Qualification in accordance with EN ISO 9712 is mandatory.
• Equipment & probes:
  • Instruments with A-scan presentation conforming to EN 12668-1.
  • Probes per EN 12668-2; nominal frequency 1–6 MHz.
  • Normal-beam probes: effective diameters 10–40 mm.
  • Angle-beam probes: angles 35°–70°; effective area 20–625 mm².
  • Dual-element probes required when near-surface testing is specified.
• Calibration & reference blocks: Calibration blocks per EN ISO 2400; reference blocks should represent the tested surface and typically include at least three reflectors to cover the depth range when using DAC/DGS techniques.
• Sensitivity & sizing: Sensitivity setting using DAC (distance-amplitude curve) or DGS techniques as specified; EN provides rules for recording levels, acceptance criteria, classification and sizing of discontinuities.
• Scanning & coverage: Defines grid scanning vs 100% coverage, scanning speeds, and special requirements for complex forgings (Clause 12).

Applications

• Quality control and acceptance testing of heat-treated and forged ferritic/martensitic steel components used in oil & gas, rail, heavy machinery, and general engineering.
• Incoming inspection, production-stage inspection, and final inspection where manual ultrasonic NDT is required.
• Useful for suppliers, NDT technicians, QA/QC engineers, and purchasers who need to specify agreed UT techniques, acceptance criteria and documentation requirements.

Who should use this standard

• NDT service providers and certified UT operators (per EN ISO 9712)
• Forging manufacturers and quality managers
• Procurement/specification engineers defining inspection requirements for steel forgings
