SAE Stone Hammer Blow Test Instrument,
MULTI GRIT TESTER 508 SAE

Purpose and Application
The new MULTI GRIT TESTER 508 SAE is a stone hammer blow testing instrument equipped with an adjustable impact angle, contrary to the execution of VDA.
Contrary to the VDA version, the test panel in the MULTI GRIT TESTER 508 SAE is located completely within the testing room during the whole bombardment procedure.
Due to numerous technical differences between both versions (conditional on the standards), a test in accordance with VDA using the SAE version, is not intended and thus technically excluded.
Accessories (option)
Impact Cabinet RIMpact I (for models 508/SAE and VDA)
Enables the user to test complete rims respectively in principle also several other specimen, which up to now – due to their big sizes – would have to be previously segmented by cutting them.
The wheel rim to be tested is turnably fixed, so each single spoke can be tested differently by choice with varying combinations of shot gravel, shoot cycles, shot gravel quantities, shoot periods and shoot pressures (under an impact angle of 90°).
So, the user is free to use it in accordance to the current standards’ stipulations he has to follow as well as for individually tailored tests.
