Prova pa shkatërrim në tuba çeliku - Pjesa 12: Prova e plotë periferike automatike e trashësisë me ultratinguj e tubave prej çeliku pa tegel saldimi dhe me saldim (përveç saldimit me hark të zhytur) (ISO 10893-12:2011)
Non-destructive testing of steel tubes - Part 12: Automated full peripheral ultrasonic thickness testing of seamless and welded (except submerged arc-welded) steel tubes (ISO 10893-12:2011)
ISO 10893-12:2011 specifies requirements for the automated full peripheral ultrasonic testing of seamless and welded steel tubes, with the exception of submerged arc-welded (SAW) tubes, for wall thickness measurement. It specifies the testing method and corresponding calibration procedures.
It can also be applicable to the testing of circular hollow sections.
ISO 10893-12:2011 is applicable to the thickness measurement of tubes with a specified outside diameter equal to or greater than 25,4 mm and a minimum wall thickness of 2,6 mm, unless otherwise agreed on.
