KOU-2 SET (SO-2, SO-3)
The standard sample SO-2 is used in the control of products made of low-carbon and low-alloy steels with an ultrasonic flaw detector to determine:
– conditional sensitivity;
– dead zone;
– depth gauge errors;
– beam entry angle;
– width of the main lobe of the radiation pattern;
– impulse conversion factor;
– extreme sensitivity.
Standard sample SO-3 is used to determine the exit point of the ultrasonic beam and the transducer boom of the ultrasonic flaw detector. It can be used to determine the propagation time of ultrasonic vibrations in the transducer prism.
Specifications:
– made of steel grade 20 or steel grade 3 according to GOST 14637;
– the velocity of propagation of a longitudinal wave in the sample material at a temperature of 20±5 °C is 5900±59 m/s;
– propagation time of ultrasonic vibrations in the forward and reverse directions 20±1 µs;
-geometric dimensions comply with the requirements of GOST 14782
