This European standard replaces the previous national standards such as NFA 09 - 205
(AFNOR) or BS 3971. IE-NDT Ltd. manufactures EN 462-2 IQIs in steel as standard and can also manufacture them in aluminium, copper and titanium to order.

There is a direct correlation between the specified EN models and the previous AFNOR types:

   AFNOR Model  H3   HA   HB    C
   EN Model         H1   H5   H9   H13

Description. The EN 462-2 IQIs manufactured by IE-NDT Ltd comprise six plaques, measuring 5 x 7mm, 7 x 10mm or 15 x 15mm, which are encapsulated in transparent plastic along with an identification monogram in cast white metal. Each plaque has one or two through-drilled holes whose diameter is the same as the plaque thickness. The IQIs are supplied in a wallet with a Declaration of Conformity.

Quality Assurance. Manufacturing, including inspection, follows a written procedure, which forms part of a Quality Management System registered according to ISO 9001. Each IQI carries a unique serial number. The Declaration of Conformity provides a complete manufacturing history.

The monogram within the IQI identifies the model, for example, H 13 FE means:
H = Hole type IQI, 13 = Number of the thinnest step, FE= Steel.
