Test Blocks

Test Blocks and Calibration Test Blocks are essential for all NDT inspections.

We offer a full range of Eddy Current (ECT) Test Blocks and hold plenty in stock for those times when they seem to just disappear from your inspection kit!

As leaders in Eddy Current (ET) NDT, we also understand the need for EC Test Blocks to be perfectly set is essential. We ensure that all our test blocks are delivered in a timely matter and ready to test from the first moment. If you have a specific Eddy Current (ECT) Test Block query, please email us directly via​ sales@ethernde.com

Conductivity Test Blocks (ATBC)

Used as a reference in the application of electrical conductivity measurement of non-ferrous metals, ideal for both laboratory and field use.

All supplied blocks are calibrated and the certification of the equipment used in this process is traceable to the National Physics Laboratory (NPL) and the National Institute of Standards and Technology (NIST), and calibrated in accordance with ASTM B193-02.

Blocks are calibrated at 20oC, at a frequency of 60 kHz and to an accuracy of +/- 1.2% of the value or +/-0.4% IACS, whichever is less.

NB Conductivity Values vary, for current stock values contact us via sales@ethernde.com
