5. Test Notes

Preparation of Specimen

(1) At least three specimens of the same size are prepared for each test. The specimens are rectangular, 110 mm in length, 50 mm in width and 2 mm or 4 mm in thickness. Thickness should be measured at approximately 6 points of equal distance along the length of the specimen, and the difference between the measured value and the average value of each point should not exceed (±5%).

(2) The surface of the test piece should be clean. When necessary, the test piece can be gently scrubbed with clay mixed with water, then rinsed with distilled water, and then dried in the air. When scrubbing, the surface of the test piece should not be damaged, and the test piece should not be cleaned with organic solvent which has corrosive or swelling effect.

(3) The vulcanized or plasticized specimens should be placed for at least 16 hours before they can be used for the test, but the longest time should not exceed 28 days. The test piece used as a contrast test has the same storage time as possible.

6. Pretreatment Before Test

(1) The two ends of the sample are clamped in two current electrode fixtures and placed on the insulating board. The sample is heated for 2 hours at (70±1)℃ in a thermostat.

(2) After heating, the samples, current electrodes and insulating plates were taken out and placed for 16 hours under the environment of (23±2)℃ and (50±5)% relative humidity.
