Wire Type Image Quality Indicators EN 462-1

Wire type IQIs to EN 462-1:1994 manufactured by IE-NDT Ltd. comprise seven parallel wires 10, 25 or 50mm long, which are encapsulated in thin, transparent plastic along with a radio-opaque identification plaque. Each IQI is supplied in a wallet. For ease of recognition, the wallet carries stickers showing the IQI model and wire length it contains. These are colour coded:

• Blue – Steel
• Yellow – Aluminium
• Red – Copper
• White – Titanium

. The wires in models W1, W6 and W10 as well as W13 in FE and CU are encapsulated in thin PVC. Because of the low radiation energy normally appropriate when models W13AL and W13TI are used, these wires are encapsulated in thin, less radiation absorbent polythene (complies with Standard requirement 4.2 ).

Domain of use:

• W1 type – 40 – 160 mm
• W6 type – 12,5 – 50 mm
• W10 type – 5 – 20 mm
• W13 type – 2,5 – 10 mm
