Stone Chip Tester 508 VDA |
Application |
The 508 VDA Stone Chip Tester was originally developed together with the German Association of the Automotive Industry (VDA), but now also complies with other national and international standards. |
For easier handling, a pneumatic sample clamping device is available on request. |
It tests the resistance of single or multi-layer paints and similar coatings to impact from small, fast-moving stones, simulating what vehicles encounter on the road. |
Optional accessories |
PSA D24 1312 test kit, perpendicular impact, angle 90°. |
Test principle |
A set quantity of impact media of specified shape, material and surface strikes the sample within a specified time, at a defined impact energy and impact angle (DIN/ISO 54°). |

Design and mode of operation |
The 508 VDA Stone Chip Tester is a high-precision test instrument. It is characterised by good repeatability and comparability of results. The sample is struck by sharp-edged steel grit accelerated by compressed air. The unit has an air reservoir that removes the effect of pressure fluctuations in the external air supply. The grit is fed automatically by an adjustable vibrator. A multifunction display shows working pressure, test time, vibrator speed and number of tests (total / resettable). |
508 SAE Stone Chip Tester |
Purpose and application |
The new 508 SAE Stone Chip Tester is an instrument for impact testing with gravel; unlike the VDA version, its impact angle is adjustable. |
Unlike the VDA version, in the 508 SAE the sample sits entirely inside the test chamber throughout the impact. |
Because the two instruments differ technically in many respects (conditions set by the standards), VDA tests cannot be carried out on the SAE version. |

The grit is fed automatically by an adjustable vibrator. A multifunction display shows working pressure, test time, vibrator speed and number of tests (total / resettable). The unit has an air reservoir that removes the effect of pressure fluctuations in the external air supply. |
Users can test a complete wheel rim, and in principle several other samples can be placed in the chamber too. Previously, rims were too large and had to be cut up before testing. |
Once fixed, the rim can be rotated, so each spoke can be tested differently by choosing different impact media, number of impacts, media mass, impact cycles and impact pressure. |
The impact angle can be adjusted in the 508 SAE sample holder, from 30° to 90° in 15° steps. |
So besides testing to current standards, users can also run their own custom tests. |
Like the VDA version, the 508 SAE gives results with good repeatability and comparability. The sample is struck by specified gravel (to ASTM D 3170) accelerated by compressed air. Other impact media can be chosen as required by other test standards (mostly automotive standards). |
