EN 462-1 Image Quality Indicators (I.Q.I’s) - Penetrameters,

RADIOGRAPHY Accessories

EN 462-1 Wire Type were introduced as a EUROPEAN STANDARD to supersede the

German Standards

(DIN 54.109) and the British Standards Institute (BS3971:1980 type 1) Image Quality

Indicators. Each

indicator consists of a series of seven parallel wires of different thichkness mounted and

encapsulated

between two thin sheets of transparent, flexible PVC. A lead monogram indicates the

number of the thickest wire, the material and the EN symbol.

Wire Diameters:

Indicator Sizes:

There are four sizes of EN Image Quality Indicators.

Size 1 – contains wire numbers 1 to 7 and used for material thicknesses in

the range of 40 t 160mm

Size 6 – contains wire numbers 6 to 12 and used for material thicknesses in

the range of 12.5 to 50mm

Size 10 – contains wire numbers 10 to 16 and used for material thicknesses

in the range of 5 to 20mm

Size 13 – contains wire numbers 13 to 19 and used for material thicknesses

in the range 2.5 to 10mm

All sizes are available in Steel(Fe), Aluminium(Al), and Stainless Steel(SS). Copper(Cu),

Zirconium(ZR) Image Quality Indicators are only available in sizes 6 and 10. Nickel(Ni)

Image Quality Indicators are only available in sizes 6, 10 and 13.

As an illustration the identification (i.e. lead monogram) for, say Size 10 (Wire numbers 10

to 16) in steel(Fe) would be 10 FE EN.
