Patent ID: 7726191

Claim:
A method for ultrasonic testing of an object, wherein at least one test moment an ultrasonic test signal (S 1 , S 2 ) is transmitted into the object, while after a particular verification period (Δt 1 , Δt 2 ) measured from said test moment, an ultrasonic verification signal (S 1 ′, S 2 ′) is transmitted into the object, a possible echo of said test signal (S 1 , S 2 ) being received from said object at a particular first measuring moment, the possible echo being accepted as being the echo (E 1 , E 2 ) of said test signal (S 1 , S 2 ) only when an echo (E 1 ′, E 2 ′) of the verification signal (S 1 ′, S 2 ′) is received at a particular second measuring moment.
