Impact Testing

MULTI GRIT TESTER 508 SAE

The MULTI GRIT TESTER 508 SAE features, like the VDA version, a good repeatability and reproducibility of the test results. The bombardment of the test panels is carried out with determinate grit (according to ASTM D 3170) which is accelerated by compressed air.
Dependent of the specifications of further standards (mostly of car manufacturers) other shot materials can be used, too.
The shot is entered automatically using an adjustable vibratory feed. On a multifunctional display the working pressure, the duration of the test, the setting of the vibratory feed and the number of tests conducted (total / temporary) can be read off alternatively.
An air accumulator in the system eliminates effects of momentary pressure variations in the external compressed air supply.
The specimen fixing device of the MULTI GRIT TESTER 508 SAE is provided with an adjustable impact angle.
The adjusting unit for the impact angle allows to adjust the orientation of the test panel relative to the direction of impact in the range from 30° to 90° in steps of 15°.
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.

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.

Test principle: A defined number of impact bodies of specified properties is made to impinge for a given period of time and with a defined energy at a determinate angle of impact onto the specimen.
