EN 462-1:1994-ISO 19232 Wire Type were introduced as a EUROPEAN STANDARD to supersede the German Standards Institute (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 thickness 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 lengths ; 10mm, 25mm , 50mm or 100mm (Please state length required when ordering)
Wire Spacings Available :Standard 5mm or 2.5mm
There are four sizes of EN-ISO Image Quality Indicators.
Size 1 – contains wire numbers 1 to 7 and used for material thicknesses in the range of 40 to 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
Available Materials: Carbon Steel (Fe), Stainless Steel (SS), Aluminium (Al), Copper (Cu), Titanium (Ti) Inconel (IN)
As an illustration the identification (i.e. lead monogram) for, say Size 1 (Wire numbers 1 to 7) in carbon steel (Fe) would be 1 FE EN
All EN-ISO Image Quality Indicators are individually numbered and supplied with a Certificate of Conformity
