Pro-NDT ASTM Step is a high-precision step wedge designed for quality assurance of digital detector systems, according to the ASTM E2597‑07 standard (Standard Practice for Manufacturing Characterization of Digital Detector Arrays).

Key features and benefits

• Consists of three step-wedge variants in different materials: aluminum 6061, titanium Ti-6Al-4V, and Inconel 718 — allowing for testing under different attenuation conditions.

• Dimensions for the variants:
  Aluminum 6061: 210 × 175 × 100 mm
  Titanium Ti-6Al-4V: 210 × 175 × 30 mm
  Inconel 718: 210 × 175 × 12.5 mm

• CE certified and designed in accordance with international requirements for NDT image quality indicators.

• Provides repeatable and documentable measurement of step-wedge curves, which is important for evaluating detector performance (linearity, contrast, dose-response).

Technical specifications

• Materials: Aluminum 6061, Titanium Ti-6Al-4V, Inconel 718.

• Dimensions: 210 × 175 × 100 mm (Aluminum) / 210 × 175 × 30 mm (Titanium) / 210 × 175 × 12.5 mm (Inconel).

• Standard: ASTM E2597-07.

Areas of application

• Quality control (QA) of digital detector systems in non-destructive testing (NDT) — for example, X-ray images with digital plate or flat panel detectors.

• Documentation and assessment of detector performance over time: linearity, contrast action, step-wedge response.

• Use in production, verification and acceptance testing of digital detector systems according to ASTM standards.
