ASTM E-747

EN 462-1 Wire type Image Quality Indicators / IQIs.

The International Standards Organisation issued Standard No ISO 19232 in June 2013. This replaces EN 462-1 but there is no practical difference as the Standard states that “EN wire IQIs of EN 462-1:1994 and its designation are identical with ISO wire IQIs” The wire diameters and system of numbering follow the previous DIN practice. IE-NDT manufactures EN 462-1 IQIs in steel (FE), Aluminium (AL), Copper (CU) and W6, W10 and W13 Titanium (TI). Description. 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:
