Overview
EN 2004-7:2017 (CEN) specifies reference blocks for the calibration of eddy‑current electrical conductivity measuring equipment used on wrought aluminium and aluminium alloys. It defines three hierarchical block types - master reference standards, secondary reference blocks, and operating reference blocks - and covers their production, calibration, identification, recordkeeping and calibration schedules. EN 2004-7 is intended to be used in conjunction with EN 2004-1 (determination of electrical conductivity) and references ISO 10012-1 for uncertainty evaluation and metrological confirmation.
Key topics and technical requirements
- Definitions and traceability:
- Master reference standards: held by National or Accredited Laboratories and traceable to electrical standards.
- Secondary reference blocks: calibrated against master standards; used to maintain traceability.
- Operating reference blocks: calibrated against secondary blocks for routine instrument calibration.
- Calibration environment and normalization:
- Calibrate at 20 °C ± 2 °C, results normalized to 20.00 °C.
- Temperature stability during operating-block calibration: actual variation within ±0.5 °C.
- Physical and material requirements:
- Surface roughness not greater than R = 1.6 µm.
- Secondary blocks: square or circular, thickness ≥ 4 mm, sides/diameter ≥ 30 mm (dimensions must avoid edge effects).
- Anodised protection layers (10–15 µm) must have lift‑off compensation applied.
- Performance and uncertainty:
- Surface conductivity variation (eddy current) should not exceed 0.05 MS/m; frequency-dependent variation (10 kHz–100 kHz) also ≤ 0.05 MS/m.
- Secondary block certificates: electrical conductivity in MS/m, test frequency and normalization temperature; maximum overall uncertainty ≤ ±0.7% (95% confidence).
- Calibration practice:
- Typical calibration frequency: 60 kHz (or within master standard’s calibrated range).
- Eddy‑current meter verification: meter must read secondary block certified value within ±0.2 MS/m or ±0.3% IACS before use.
- Operating block readings acceptable if within ±2 MS/m or ±3.5% IACS of the applicable secondary block; linear (or non‑linear) interpolation is permitted to determine calibrated values.
- Schedules and records:
- Secondary blocks: calibrated at intervals ≤ 4 years.
- Operating blocks: calibrated at intervals ≤ 13 months.
- Unique identification, calibration dates, uncertainty and full calibration records required.
Applications
- Ensures reliable calibration of eddy‑current conductivity equipment used in:
- Aerospace manufacturing and inspection of wrought aluminium components.
- Quality control labs and NDT facilities measuring aluminium alloy conductivity.
- Materials verification where conductivity is used to infer alloy composition, heat‑treatment condition or electrical performance.
Who should use this standard
- Aerospace manufacturers, NDT service providers, calibration laboratories, quality assurance personnel, and national standards bodies who require traceable, reproducible electrical conductivity measurements on aluminium alloys.
