Ultrasonic test block

Gentlemen,
What is the designation "TIF-block" referring to? Is it a block for setting gain levels?
Regards
Nick

Hello Nick,

sometimes a gamma projector called " bloc " . There was the former company " Sauerein " which produced a kind of gamma projector called " Gammamat TIF "

Maybe only an idea !

Christoph,
I should have been more specific: it is an ultrasonic reference block with what appears on the sketch to be three cross-drilled holes. The item is from a European document.

(I have seen the Saurwein Gammamat-TIF, also remember fondly the excellent Gammalux personal alarm)
regards
Nick

Nick

EN 583-2 has a 3 SDH block for setting sensitivity on material between 20mm and 40mm thick (Table B2 Reference blocks and reflectors for Class 1 objects.

Could it possibly read ToF instead of TIF, in which case it could be a TOFD block from Annex A of EN 583-6?

If it has crossed drill holes it was probably used to set gain levels to check welding seams.
Usually they have to be calibrated once a year (compared to a master block).
Most test blocks have flat bottom holes.
