Keywords: Industrial Polymers

Test Performed by: Maxim Technologies/Twin City Testing, 662 Cromwell Avel, St. Paul, Minnesota 55114

Project No.: 301898-67029

Introduction: This report presents the results of Dielectric tests conducted on 9 samples of polymer blocks. The test samples were submitted to our laboratory by Mr. Carl Boddie of Industrial Polymers Inc. on June 27, 1998. The scope of work was limited to conducting a Dielectric Proof test on the samples and providing a factual report of the results. Testing was completed on July 2, 1998.

Sample Identification: A total of 9 samples were submitted for testing. The samples were identified as shown below:

Sample ID Description
1 1 1/4", CS-100, yellow, studs, CS-200 non skid, CS-300 top coat
2 3/4", CS-100, yellow, studs, CS-200 non skid, CS-300 top coat
3 3/4", CS-100, yellow, no studs, CS-200 non skid, CS-300 top coat
4 1/2", CS-100, yellow, no studs, CS-200 non skid, CS-300 top coat
5 1 1/4", gray, no coating, no studs
6 3/4", gray, no coating, no studs
7 1/2", gray, no coating, no studs
8 1 1/4", yellow, no coating, no studs
9 3/4", yellow, no coating, no studs

Results (ok indicates that no breakdown was observed):

Sample Thickness 10,000 VAC 25,000 VDC
1 1 1/4" ok ok
2 3/4" ok ok
3 3/4" ok ok
4 1/2" ok ok
5 1 1/4" ok ok
6 3/4" ok ok
7 1/2" ok ok
8 1 1/4" ok ok
9 3/4" ok ok

Dielectric Test Method: The test was conducted using the methodology of ASTM:D149. Samples were tested using both Direct Current and Alternating Current. Electrodes (2 each) were machined from Brass round stock to a diameter of 1 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 25,000 VDC. These conditions were maintained for a period of 1 minute. After this period, the voltage was slowly reduced to 0 VDC. during this period, observations were made for evidence of breakdown.

This procedure was repeated except that a voltage of 10,000 VAC was used.

This procedure was repeated on an additional 8 samples.

Instrumentation: Dielectric Tester Hipotronics, Model Number HD-100, Serial Number: MM180-012, Calibrated 10/24/97, Calibration Due: 10/24/98.
