Abstract

Specifies six methods for the determination of thickness of material based on the use of ultrasonic pulse-echo principles where scanning and reflecting surfaces are substantially parallel.

Scope

This Standard specifies six methods for the determination of thickness of material based on the use of ultrasonic pulse-echo principles where scanning and reflecting surfaces are substantially parallel. The methods are as follows:
(a) Single spot-single measurement (SS).
(b) Single spot-double measurement (SD).
(c) Multiple spot measurements (MS).
(d) Close grid survey method (CG).
(e) Open grid method (OG).
(f) Scanning runs (SR).
(g) Complete coverage method (CC).
NOTES:
1 Appendix A provides guidelines on information to be provided to the manufacturer at the time of enquiry.
2 Factors affecting the results and order of accuracy achieved are given in Appendix D.
