One test means up to 5 tests on a single material; the five tests can be conducted on different individual test specimens or on a single test specimen if ast, separation between the test locations is sufficient to avoid damage of one test to the surface of another test location.
A minimum of 5 specimens are recommended. The preferred test specimen s: The preferred test specimens are mm 4 inches diameter disks with a minimum thickness of 2. A minimum of 5 specimens per material per thickness must be tested, however, that number is only d23033 if the number of drops falls exactly in line with expectations.
The recommended minimum number of samples is 20 samples; the preferred number of samples for each material is The condition of the surface of the material will greatly effect the results. All test specimens should be free of surface imperfections such as scratches and bubbles. The surface to be tested must be specified. Flat surface approximately 2 by 5 inches 50mm by mm and of a thickness rigid enough to support itself without flexing or bending.

At least 5 specimens per material per thickness to be tested must be provided; astk preferred number is 7 specimens. Dust—and—Fog Tracking and Erosion Resistance of Electrical Insulating Materials This test method evaluates the tracking resistance of a material in a continually wet and dusty environment. This is the most harsh of the most common track resistance tests. This method evaluates surface tracking and erosion through the material.
