The current international standard for wire type Image Quality Indicators is ISO 19232-1:2013, which replaced EN 462-1:1994. Despite the change in standard number, the wire IQIs and their designations remain identical, as confirmed in the ISO text. The wire numbering and diameters follow the same format as the earlier DIN standard.
IE-NDT Ltd. supplies EN 462-1 wire IQIs in a range of materials:
- Steel (FE)
- Aluminium (AL)
- Copper (CU)
- Titanium (TI) – available in W6, W10, and W13
Description
Each IQI consists of seven parallel wires, held in place by a clear plastic strip along with a radio-opaque identification plaque. Wire lengths are available in 10 mm, 25 mm, or 50 mm versions. All IQIs are packaged in protective wallets, clearly labeled with model and length information.
The labels are colour-coded by material to make selection straightforward:
- Blue – Steel
- Yellow – Aluminium
- Red – Copper
- White – Titanium
Quality Assurance
Production and inspection follow a documented process as part of an ISO 9001-certified Quality Management System. Each IQI is marked with its own serial number for full traceability.
A Declaration of Conformity is supplied in line with ISO/IEC 17050-1, including detailed records of manufacture and individual wire measurements.
