Overview
EN ISO 5580:2023 - "Non‑destructive testing - Industrial radiographic illuminators - Minimum requirements" defines the minimum design, performance and marking requirements for industrial radiographic illuminators used to view developed radiographic films (radiographs). It specifies physical construction, viewing‑screen properties, luminance, light colour, diffusion and uniformity, safety features (anti‑glare, heating protection) and measurement methods. This EN-adopted ISO standard is essential for consistent, safe and repeatable radiographic film viewing in NDT (non‑destructive testing).
Key topics and technical requirements
- Function: Provide sufficiently diffuse, uniform light for reliable interpretation of radiographs.
- Viewing screen: Must be easy to clean, scratch‑resistant, heat‑stable and sized to prevent operator glare. Masks (internal/external) are required for different film sizes.
- Luminance (brightness): Measured in cd/m² with a luminance meter per ISO/CIE 19476 using V(λ) responsivity. The illuminator must have a variable, continuous luminance control (preferably constant‑current control to avoid pulsed illumination artifacts). Representative minimum screen luminances (Lmin) provided:
- D = 1.0 → Lmin ≈ 300 cd/m²
- D = 1.5 → Lmin ≈ 1 000 cd/m²
- D = 2.0 → Lmin ≈ 3 000 cd/m²
- D = 2.5 → Lmin ≈ 10 000 cd/m²
- D = 3.0 → Lmin ≈ 10 000 cd/m² (and higher for denser films up to 1 000 000 cd/m² for D = 5.0)
- Note: very high luminance (>300 000 cd/m²) can heat films and should be used only for short periods.
- Colour of light: Normal white light with correlated colour temperature (CCT) between 2 500 K and 7 000 K; film‑specific colours allowed if recommended by the film manufacturer.
- Diffusion and uniformity: Diffusion factor σ' > 0.7; uniformity factor g > 0.5 to ensure even illumination and viewing comfort.
- Safety features: Anti‑glare device to protect operators when films are removed; mechanical/electrical safety to conform with national electrics standards; protections against liquid ingress for wet-film viewing when required.
- Measurement & marking: Characteristics and nominal power consumption shall be determinable; marking and user recommendations included.
Applications and users
- Intended for NDT/radiography labs, welding inspection, foundries, petrochemical/aviation maintenance, and any facility performing film‑based radiographic testing.
- Primary users: NDT technicians, radiographers, QA/QC managers, procurement teams and equipment manufacturers specifying or certifying industrial radiographic illuminators.
