The insulation resistance test of the heat shrink tape is a change in the insulation resistance obtained by the test, and the sealing property of the reaction port.
Test preparation: 1, in the steel pipe filling area cut the heat shrink tape with the edge of the specimen, and with the provisions of the identification of leakage leak detection point, the specimen size of 200mm (circumferential) * 300mm (horizontal). 2, the diameter of 120mm plastic pipe with the adhesive on the surface of the specimen, the test area should be filled with the original material and half of the original coating. 3, until the glue is fully cured, the tank into the water, to the slot 3/4.
Test operation: 1, room temperature after 24 hours, with a range of 0-10 11 times the Ω of the high resistance meter to measure the resistance value of R. 2, will be filled with water samples of anti-corrosion 60 degrees Celsius oven placed 7 days. 3, after expiration, remove the specimen placed 24 hours, until the water reaches room temperature, and then measured the resistance value of R. 4, the calculation of insulation resistance: R = R. S where R --- insulation resistance, Ω.m2 R. --- test measured resistance, Ω S --- test tank test area, m2.
