Gravelometer Testing
What is a Gravelometer?
Chipping of coatings, especially on automobile surfaces, is considered undesirable. In formulating a coating or coating system to meet service requirements, the resistance to chipping damage by flying objects such as gravel is one of the properties of importance. Since resistance to chipping decreases at lower temperatures partly as the result of decreased flexibility, the test may be more directly related to service conditions by performing it at a low temperature. Gravelometer testing is designed to produce a controlled amount of impact by the media on the coated panel to enhance reproducibility.
Gravelometer testing has been conducted for more than 30 years to thoroughly evaluate the impact that flying gravel and debris has on surface coatings. Typically, gravelometer tests are conducted on the following types of automotive surface coatings: paint, clear coats, or metallic plating. Through both standard and customized gravelometer testing, ATS can successfully simulate real-life conditions.
During a typical test, the sample will be mounted to the back of a Gravelometer. Air pressure is used to propel gravel at the test sample. The sample is removed and gently wiped with a clean cloth. A tape is then used to remove loose fragments from the rest of the surface. The sample’s appearance is compared to standard transparencies and a visual examination is conducted to better determine an accurate chipping rating. ATS conducts gravelometer testing in accordance with established industry standards such as ASTM D3170 and SAE J400.
