ASTM D2303 – Inclined-Plane Tracking and Erosion Tester
For erosion studies, only tests as a function of time at constant voltage are useful. One test means up to 5 tests d23003 a single material; the five tests can be conducted on different individual test specimens or on a single test specimen if the separation between the test locations is sufficient to avoid damage of one test to the surface of another test location.
Charles, D303,http: 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. All test specimens should be free of surface imperfections such as scratches and bubbles.
Use caution when making either direct or comparative service behavior inferences derived from the results of tracking tests. The use of this method for measuring erosion is consequently important. You can unsubscribe anytime. Link to Active This link will always route to the current Active version of the standard.
The condition of the surface of the material will greatly effect the results.
The recommended minimum number of samples is 20 samples; the preferred number of samples for each material is Emails are serviced by Constant Contact. Watch our video about Inclined Plane Testing. The preferred test specimens are mm 4 inches diameter disks with a minimum thickness of 2.
The preferred test specimen s: Subscribe to our YouTube Channel. In this case, the time-to-track technique is used, since time is required to decompose the contaminant solution and build up conducting residues on the sample surface. This is the most d3203 of the most common track resistance tests. Approximately x mm and minimum of 1.
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. At least 5 specimens per material per thickness to be tested must be provided; the preferred number is 7 specimens.

Flat surface approximately 2 by 5 inches 50mm by mm and of a thickness rigid enough to support itself without flexing or bending. The effects are similar to those that may occur in service under the influence of dirt combined with moisture condensed from the atmosphere.
By submitting this form, you are consenting to receive marketing emails from: The surface to be tested must be specified. For example, an ionic contaminant containing, in addition, a carbonaceous component such as sugar is substituted to cause tracking on very resistant materials like polymethylmethacrylate.
Historical Version s – view previous versions of standard. Charles, MO Email Us. To arrange tracking tests, request a quote online now or call A minimum of 5 specimens per material per thickness must be tested, however, that number is only sufficient if the number of drops falls exactly in line with expectations. This method recognizes the importance of such variability and suggests the use of special test solutions to meet specific service needs. Such contamination is considered representative of some severe industrial environments.
A minimum of 5 specimens are recommended. This method evaluates surface tracking and erosion through the material. Specific precautionary statements are given in Section 8.
