Historical Version s – view previous versions of standard. 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. 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.
You can unsubscribe anytime. Use caution when making either direct or comparative service behavior inferences derived from the results of tracking tests. Approximately x mm and minimum of 1.
Flat surface approximately 2 by 5 inches 50mm by mm and of a thickness rigid enough to support itself without flexing or bending. Link to Active This link will always route to the current Active version of the standard. One test means up to 5 tests on a single material; the five tests can be conducted on different individual test specimens or aztm a single test specimen if the separation between the test locations is sufficient to avoid damage satm one test to the surface of another d203 location.

This method evaluates surface tracking and erosion through the material. The recommended minimum number of samples is 20 samples; the preferred number of samples for each material is The preferred test specimens are mm 4 inches diameter disks with a minimum thickness of 2. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
All test specimens should be free of surface imperfections such ashm scratches and bubbles. Charles, MO Email Us.

The use of this method for measuring erosion is consequently important. The condition asrm the surface of the material will greatly effect the results. Charles, MO,http: 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.
The preferred test specimen s: Specific precautionary statements are given in Section 8. By submitting this form, you are consenting to receive marketing emails from: Watch our video about Inclined Plane Testing. This is the most harsh of the most common track resistance tests.

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 method recognizes the importance of such variability and suggests the use of special test solutions to meet specific service needs.
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.
At least 5 specimens per material per thickness to be tested d233 be provided; the preferred number is 7 specimens. A minimum of 5 specimens are recommended. The surface to be tested must be specified.
