View our standard range of UT test blocks

At NDT Equipment, our main focus is supplying  quality products, on time. We hold an extensive range of standard UT blocks in stock ready for immediate dispatch, all meeting the relevant standards and dimensional tolerances required. For any that we do not have in stock, we are able to offer quick turnaround times to help with those urgent jobs!

We manufacture ultrasonic standard and special test blocks and test pieces, all to the most recent and up to date standards including No.1/V1s to EN ISO 2400:2012, No.2/V2s to EN ISO 7963:2010 and Ladder Step Wedges to 16946:2017.  All can be supplied in any material that you require.  Specials are manufactured to customer specifications.

We follow our strict quality assurance system (ISO 9001:2015) and provide full traceability and certification with all of our products.

We offer a full in-house measurement report using our CMM (Co-ordinate Measuring Machine) However, where UKAS is required, we can provide a full independent UKAS certification using one of our trusted suppliers.
