NIST Traceable

We recommend a yearly recalibration cycle for all IST data recorder systems. IST provides a complete recalibration service to help keep your system providing accurate results. IST has been certified to MIL-STD-45662A. All IST calibrations are traceable to the National Institute of Standards and Technology (NIST) We request customers contact IST Technical support via e-mail, fax or phone to get an RMA number before returning equipment.


IST offers ISO Z-540 certified recalibration services on all SnapShock-Plus; EDR-3/3C/3D/6DOF; EDR-4 and MSR-3C series products as well as external accelerometers. IST maintains an in-house metrology lab which supports all of these repair and re-calibration services. All calibrations are traceable to NIST.

IST generally recommends annual re-calibrations on all of its instruments referenced above.
