Overview

EN 2003-002:2023 - “Aerospace series - Steels - Test methods - Part 002: Izod impact test” (CEN, approved Feb 2023) specifies the procedure for performing the Izod impact test on steels intended for aerospace applications. It is applied when referenced in an EN technical specification or material standard and defines machine characteristics, specimen geometry, test conditions and reporting requirements to measure impact strength using a pendulum (Izod) impact machine.

Key Topics and Requirements

• Scope & principle
  • Measures energy absorbed by a notched steel specimen broken by a single blow from a swinging pendulum.
• Equipment
  • Pendulum impact machine verified per EN 2003-003.
  • Plane of pendulum swing vertical; centre of percussion at striker impact point.
  • Anvil and foundations weight ≥ 40× pendulum weight.
  • Striker speed at impact: 3.5 m·s⁻¹ ± 0.5 m·s⁻¹.
  • Specified striker geometry (e.g., tip radius ~0.75 mm ± 0.25 mm).
• Specimens (test pieces)
  • Round, machined specimens with V-notches (single, two or three notches per Annex A figures).
  • Key dimensions/tolerances: diameter 11.43 mm ± 0.025 mm, notch depth 8.13 mm ± 0.05 mm, root radius 0.25 mm ± 0.025 mm, and specified spacing/lengths.
  • Machining must minimise cold work; notches must be free from visible grooves.
• Test conditions
  • Standard ambient range 10 °C to 35 °C; in disputes use 23 °C ± 5 °C.
  • For non-ambient tests: immersion times (e.g., ≥10 min in liquid, ≥30 min in gas) and break within 5 s after removal.
• Results & reporting
  • Results in specified units (J or ft·lbf), individual and/or mean absorbed energies.
  • Test report must reference the standard and include equipment, temperature, specimen traceability, results, incidents and any deviations (see clauses a–k).

Applications and Who Uses It

• Practical uses
  • Qualifying aerospace steels for toughness and fracture resistance.
  • Material acceptance tests, design validation, supplier control and failure analysis.
• Primary users
  • Materials and mechanical engineers, metallurgical test laboratories, aerospace manufacturers, quality/inspection teams, certification authorities and procurement specialists specifying material test methods.

Related Standards

• EN 2003-003 - Calibration of pendulum impact machines (normative reference)
• EN 4258 - Organisation of the aerospace metallic material standards series
• Relevant national/adopted versions (CEN members and ASD‑STAN)
