摘要：
A statistical analysis of the variation in some of the important properties of ultrasonic probes is described. The probes evaluated by the NDT Centre's probe-beam plotter have been used as a sample. An attempt has been made to define acceptible limits to the variations in probe parameters, although these may not be of wide application since every application of ultrasonic testing defines slightly different limits of acceptability. It appears that 45% of low frequency probes and 81% of high frequency probes may lie outside these limits.
