BIS Group use of the very best materials and manufacturing techniques combined with rigorous quality control throughout the production process ensures that BIS Group Image Quality Indicators are free from defects.
Our range of Image Quality Indicators are available in European, DIN, ASTM & ASME Standards.
Manufactured in the United Kingdom in our own factory to exacting standards, by controlling the production process end to end we can ensure that quality can be assured.
This attention to detail has meant over time that BIS Group Image Quality Indicators have become the industry benchmark standard.
Each EN-747-87a type indicator consists of a series of seven parallel wires of different thicknesses and 10, 25, 50 or 100 mm long mounted between two thin sheets of transparent, flexible PVC.
A lead monogram indicates the number of the thinnest and the thickest wires, the material and includes the DIN symbol. These indicators are available in Steel (FE), Aluminium (AL), Copper (CU) and Titanium (TI).
A full range of BIS Group EN 462-1 type indicators are available in both 5 mm and 2.5 mm wire spacing see page 30 of our catalogue for further details.
BIS Group ASTM E747-87a / ASME SE747-97 a type indicators are also available in Inconel 600 alloy.
All BIS Group wire type Image Quality Indicators indicators have a unique serial number for Quality Assurance purposes and full audit traceability.
For each serial number we maintain full records of the wire type, actual measured wire diameters and date of manufacture.
