accelerated test definition

An accelerated test is a test of materials, such as pigments and paints, by artists.  The test is performed in a lab with certain equipment in order to simulate situations that will result in cracking, fading and other breakdowns that paintings are vulnerable to over a period of time.  Although accelerated tests do not exactly replicate normal effects aging because of their severity and concentrated forces, the tests are able to point out the resistance/lack of resistance that ingredients and materials may manifest when put under severe forces.
