| Significance and Use | ||||||||||||||||
|
4.1 Owners consider chipping of coatings, particularly on the leading faces and edges of automobile surfaces, unacceptable. 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 it can vary considerably as other properties are adjusted. 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. This test method is designed to produce a controlled amount of impact by the media on the coated panel in order to enhance reproducibility. |

| 1. Scope | ||||||||||||||||
|
1.1 This test method covers the determination of the resistance of coatings to chipping damage by stones or other flying objects. 1.2 The values stated in metric
units are to be regarded as the standard. The English units given
in parentheses are for information only. All dimensions are nominal
unless otherwise specified.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
