Adhesive Shear Testing Equipment Tape Holding Power Lasting Test ASTM D 3654
The holding power of pressure-sensitive tapes, to do a static load test for the adhesive force of the tape, automatically under a certain load,Record the time that the tape can hold to confirm the aging of the tape. Cut a 1 inch wide strip The tape is attached to the specified SUS#304 stainless steel plate, and is passed through a 2kg standard roller at a speed of 300mm per minute. Roll back and forth once, hang the steel plate on the testing machine, add the specified weight, generally 1kg when the tape comes from the steel plate, after falling, the timer automatically keeps the test time

Test Steps :
1. Take a certain length of adhesive tape to be tested, place it on the attached test board, use a roller with a weight of 2000gf±50gf at a speed of 300mm/min
Roll back and forth 3 times to make the adhesive tape evenly adhere to the test board (generally 1"×1" or according to relevant test standards), prepare ten sets of test boards according to this method.
Note: The test board is made of #304 mirror steel plate. After the sample is pasted on the test board, it should be placed at a temperature of 23℃±2℃ and a relative humidity of 65%±5%.
20 minutes, then hang on the hooks in the testing machine.
2. Gently connect the connecting piece and the weight (the choice of weight depends on the material). After hanging the weight, the timer automatically starts timing.
3. When the tape falls off, it automatically stops timing and keeps the tested time, and reads the adhesive time of the tape. If the time is greater than 1h, take min as the unit, smaller
In 1h, the unit is s. Or after the specified time, when the sample has not fallen off, use the indexed magnifying glass to measure the sliding displacement of the sample, accurate to 0.1mm
4. Before each test, be sure to reset the timer to zero.
