Dimensional testing in UT

Dear Friends

Ultrasonic testing is used for thickness measurement and in some application by using software features it can be used to calculate OD, ID and ovality of rounded tubes / pipes.

I am using automated immersion ultrasonic testing for dimensional measurement (OD & wall thickness) of stainless steel tubes.

My question is for thickness measurement is there any requirement for machined samples as a standard reference calibration sample to calibrate my UT system for lower and higher range?

As per my view two samples one nearer to lower thickness and one nearer to higher thickness withing the specified tolerance range shall be used. am i right or if i am wrong plz let me know other aspects.

Please mentioned the code reference for such requirement if any..

l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
