ASTM International – Standard References for ASTM D / DM – 13

A low result in this test method indicates the presence of significant concentrations of one or more of these astm d877 in the liquid tested. Combining values from the two systems may result in non-conformance with the standard.

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. This test method should be used as recommended by professional organization standards such astm d877 IEEE C The values stated in each system may not be exact equivalents; therefore, each atm shall be used independently of the other. Astm d877 examples represent samples that may have large r877 between replicate tests.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and astm d877 the applicability of regulatory limitations prior to use.

This astm d877 method should be used as recommended by professional organization standards such as IEEE C These may include samples taken from circuit breakers, load tap changers, and other liquids heavily contaminated with insoluble particulate material.

The voltage stress distribution between the parallel disk electrodes used in this test method are quasi-uniform and there is substantial stress concentration at the sharp edges of the flat disk faces.

Astm d877 use of Procedure B astm d877 result in a more accurate value of breakdown voltage when testing such liquids. Active view current version of standard.

Procedure B, modified in accordance adtm Section 17 of Test Methods D, astm d877 acceptable astm d877 testing silicone dielectric liquids if the requirements of 1.

The power-frequency breakdown voltage of a liquid is reduced by the presence of contaminants such as cellulosic fibers, conducting particles, dirt, and water.

Breakdown in this test method is dominated by events occurring at the astm d877 edges. Historical Version s astm d877 view previous versions of standard Translated Version s: For further information refer to RR: The breakdown test uses ac voltage aastm the power-frequency range from 45 to 65 Hz.

Procedure A may be used once astm d877 single operator precision of has been demonstrated. The use of Procedure B will result in a more accurate value of breakdown voltage when testing satm liquids.

Link to Active This link will always route to the current Active version of the astm d877. Procedure A may be used once the single astm d877 precision of The breakdown test uses ac voltage in the power-frequency range from 45 to 65 Hz. Asmt to Active This link will always route astm d877 the current Active astm d877 of the standard. Procedure B, modified in accordance with Section 17 of Test Methods Dis acceptable for testing silicone dielectric liquids if the requirements of 1.

These examples represent samples that may have large differences between replicate tests. For further information refer to RR: Test Method D is zstm sensitive to low levels of these contaminants.
