Are there any standards for pulse echo testing?

Pulse echo testing is included in the European standard EN 12504-4 for pulse velocity determination. This is then subsequently included in the standard EN13791 for in-situ compressive strength estimation. The application is also covered in a number of guidelines. The most comprehensive of these is the German Society for Non-Destructive Testing Guideline B4. It is also covered in a German highway authority guideline for measuring tunnel lining thickness (ZTV-ING Teil 5 Tunnelbau) and ACI 228.2R.
