DC voltage levels in parallel to AC voltage in the ASTM inclined plane tracking and Index Terms — DC Inclined plane test, tracking and erosion, ASTM D ASTM D Standard Test Methods for Liquid-Contaminant, Inclined-Plane Tracking and Erosion of Insulating Materials. The use of polymers covered cables for medium voltage electricity distribution grids is an attractive option in Brazil thanks to their low cost and simplic.

This method evaluates surface tracking and erosion through the material. Watch our video about Inclined Plane Testing. 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.
Approximately x mm and minimum of 1. By submitting this form, you are consenting to receive marketing emails from: Specific precautionary statements are given in Section 8. The use of this method for measuring erosion is consequently important.
Aastm surface to be tested must be specified. 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. For erosion studies, only tests as a function of time at constant voltage are useful.
Subscribe to our YouTube Channel. This is the most harsh of the most common track resistance tests.
ASTM Testing Procedures And Test List: Eltek International Laboratories
The preferred test specimens are mm 4 inches diameter disks with a minimum thickness of 2. Use caution when making either direct or comparative service behavior inferences derived from the results of tracking tests.
Emails are serviced by Constant Contact. 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. 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.
This method recognizes the importance of such variability and suggests the use of special test solutions to meet specific service needs. The effects are similar to those that may occur in service under the influence of dirt combined with moisture condensed from the atmosphere. Referenced Documents purchase separately The documents listed below are referenced within the subject standard ashm are not provided as part of the standard.

Such contamination is considered representative of some severe industrial environments. To arrange tracking tests, request a quote online now or call Charles, MO Email Us. Charles, MO,http: Link to Active This link will always route to the current Active version of the standard. A minimum d23003 5 specimens per material per thickness must be tested, however, asym number is only sufficient if the number of drops falls exactly in line with expectations.

Historical Version s – view previous versions of standard. At least 5 specimens per material per thickness to be tested must be provided; the preferred number is 7 specimens.
The preferred test specimen s: You can unsubscribe anytime. For example, an ionic contaminant containing, in addition, a carbonaceous component such aastm sugar is substituted to cause tracking on very resistant materials like polymethylmethacrylate. The recommended minimum number of samples is 20 samples; the preferred number of samples for each d23003 is A minimum of 5 specimens are recommended.
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 the separation between the test locations is sufficient to avoid damage of one test to the surface of another test location.
Flat surface approximately 2 by 5 inches 50mm by mm and of wstm thickness rigid enough to support itself without flexing or bending.
