Charles, MO,http: Subscribe to our YouTube Channel. Such contamination is considered representative of some severe industrial environments. This is the most harsh of f2303 most common track resistance tests. Flat surface approximately 2 by 5 inches 50mm by mm and of a thickness rigid enough to support itself without flexing or bending. The use of this method for measuring erosion is consequently important. The preferred test specimen s: A minimum of 5 specimens are recommended.

Use caution when making zstm direct or comparative service behavior inferences derived from the results of tracking tests. 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.

To arrange tracking tests, request a quote online now or call Approximately x mm and minimum of 1. One test means up to 5 tests on a single material; the five tests can be conducted on e2303 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.


The condition of the surface of the material will greatly effect the results.

A minimum of 5 specimens per material per thickness must be tested, however, that satm is only sufficient if the number of drops falls exactly in line with expectations. For erosion studies, only tests as a function of time at constant voltage are useful. Link to Active This link will always route to the current Active version of the standard.

The preferred test specimens are mm 4 inches diameter disks with a minimum thickness of 2. Charles, MO Email Us. This method evaluates surface tracking and erosion through the material.

The effects are similar to those that may occur in service under the influence qstm dirt combined with moisture condensed from the atmosphere. The recommended minimum number of samples is 20 samples; the preferred number of samples for each material is Historical Version s – view previous versions of standard.

For example, an ionic contaminant containing, in addition, a carbonaceous component such axtm sugar is substituted to cause tracking on asmt resistant materials like polymethylmethacrylate. At least 5 specimens per material per thickness to be tested must be provided; the 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.

The surface to be tested must be specified. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Specific precautionary statements are given in Section 8.

Emails are serviced by Constant Contact. All test specimens should be free of surface imperfections such as scratches and bubbles. This method recognizes the importance of such variability and suggests the use of special test solutions to meet specific service needs.
