Double Wire Image Quality Indicator Tungsten Platinum Wire

Double Wire Image Quality Indicator Tungsten Platinum Wire

The dual-wire IQI employs 13 sets of precise tungsten-platinum wires to achieve the imaging limit of "clear → unclear", directly quantifying the total image blurriness (U = 2d) and spatial resolution (SRb = d) of the radiographic images. It is the gold standard tool for evaluating the performance of NDT imaging systems.

Standards: EN462-5 and ASTM E2002 optional

13 groups of double wires (1D to 13D): The diameter decreases from 0.80mm (1D) to 0.05mm (13D).
1D to 3D: **Tungsten (W)** wire (purity ≥ 99.90%)
4D to 13D: **Platinum (Pt)** wire (purity ≥ 99.95%)
Key design: Wire spacing = Wire diameter (d)
Packaging: Embedded in a low-absorption plastic substrate to ensure the parallelism and precise spacing of the wire pairs.
