This European Standard specifies the requirements for the manufacture, checking and marking of the series of ultrasonic testing reference blocks containing flat bottom holes (FBH) which define the indicated defect size to which reference is made in EN standards.
The application of ultrasonic testing reference blocks containing side drilled holes (SDH) which define an indicated defect size shall be agreed between manufacturer and purchaser.
This standard is applicable to the production of master and standard test blocks to be used when carrying out ultrasonic inspection to the requirements of EN 4050 1 (FBH method).
It is recognized that particular difficulties are encountered with round forging stock and bars due to the wide range of curvatures. For this application, only one block shall be produced to act as both master and standard test block.
