Overview
EN 16714-2:2016 - “Non‑destructive testing - Thermographic testing - Part 2: Equipment” (CEN) specifies properties and requirements for infrared (IR) cameras used in thermographic testing for non‑destructive testing (NDT). The standard guides selection, classification, accessory use, function checks and traceability of cameras and gives examples of excitation sources used in active thermography. It complements EN 16714‑1 (general principles) and EN 16714‑3 (terms and definitions).
Key topics and technical requirements
- IR camera selection: choose cameras based on application and object temperature. Manufacturers must provide key parameters.
- Classification:
- By detector arrangement: single‑element (scanning), line scanners, or two‑dimensional focal plane arrays (FPA).
- By detector type: thermal detectors (e.g., microbolometers) vs. quantum detectors (cooled).
- Essential camera parameters:
- Temperature range (specified for black‑body, ε = 1; may be affected by filters).
- Thermal resolution: expressed as NETD (Noise Equivalent Temperature Difference). Typical NETD around 300 K: ~0.05 K for uncooled thermal detectors and ~0.02 K for cooled quantum detectors.
- Spatial resolution: characterized by IFOV (instantaneous field of view), SRF (slit response function), HRF (hole response function). Typical single‑element horizontal IFOV ~1 mrad for a 20° FOV with 320 pixels.
- Temporal performance: frame rate and response time - scanning systems limited (~30 s‑1), FPA uncooled ~60 s‑1, cooled quantum FPAs up to ~300 s‑1 full frame and much higher for windowed frames (up to ~70 000 s‑1).
- Operating and storage temperature ranges.
- Spectral filters: adapt camera sensitivity to material absorption/transmission bands (SW, MW, LW bands).
- Accessories: interchangeable lenses (require calibration with camera), IR mirrors, IR protective windows, protective housings.
- Active thermography excitation examples: flash lamps (pulse thermography), lamps/LEDs/lasers (modulated or pulsed), hot/cold air for convective excitation.
- Function checks & traceability: defines user checks, supplier checks, and recommended frequency of checks to ensure measurement reliability.
Applications and target users
- Practical uses: detection of delaminations, voids, moisture ingress, hot‑spots in electrical equipment, composite inspection, pipeline and building diagnostics.
- Primary users:
- NDT engineers and inspectors performing thermographic inspections
- Manufacturers of IR cameras and accessories
- Calibration and testing laboratories
- R&D teams developing active thermography methods
- Asset managers and maintenance teams seeking reliable inspection protocols

wavelength between approx. 2,0 µm and 5,0 µm; — long Wave, LW: wavelength between approx. 8,0 µm and 14,0 µm. 4.2.2 Temperature range The temperature range is the interval between lowest and highest measurable temperature. The range should be specified for black-body temperatures (emissivity = 1). NOTE 1 Temperature range means the total temperature range, which can consist of several partial measurement ranges that can be adjusted separately at the device. NOTE 2 The use of optical components like spectral filters can alter the measurable temperature range. 4.2.3 Thermal resolution The thermal resolution describes the ability of an IR camera to resolve small temperature differences. The thermal resolution is commonly described by the noise equivalent temperature difference (NETD, see A.5). The thermal resolution depends among others on: — the object temperature; — the integration time or response time; — the temperature range. Therefore, it shall be specified at least with indication of these values. The required thermal resolution depends strongly on the application. SIST EN 16714-2:2016
