INDEPENDENT DIELECTRIC STRENGTH TEST
Bronz-Glow 698
Dielectric Strength Testing conducted using methodology
of ASTM D-149. The scope of the work was limited to conducting
the dielectric strength tests on the 20 specimens submitted.
The test was complete January 30, 2001.

Specimen Description
Twenty (20) specimens approximately 3” x 3”,
Ten Red and Ten Black, Coating Bronz-Glow F-855
Testing Method
The test was conducted in accordance with ASTM D-149. Samples
were tested using alternating current, electrodes two each
machined from brass round stock to a diameter of 1.00 inches.
The test sample was placed between the electrodes. The
probes of the dielectric tester were attached to the electrodes.
The voltage was increased slowly to 10,000 VDC. These conditions
were maintained for a period of one (1) minute. After this
period the voltage was slowly reduced to 0 VDC. During
this period observations were made for evidence of breakdown.
Test Equipment
Mitutoyo Micrometer, MM-160016, S/N 14862, calibrated 4/28/00,
next due 4/28/01. Model HD series HIPOT Tester, MM180-012,
calibrated 12/7/00 next due 12/7/01.
