Operation Overview Prepare test specimens Turn on the instrument and warm up for 90 min Connect the gas supply Level and balance the instrument Set up parameters Install a proper weight Mount test specimen Start test Finish test Operation Procedures Prepare Test Specimen According to ISO 291 standard, all test specimens should be conditioned at 23±2℃ and 50±5% RH for 12 hours. Two types of specimens can be tested: constant-radius and rectangular. Cut Slit Cut Slit 24 Tearing T este r SLY-S1 According to specific requirements, prepare a number of test specimens as shown in the above scheme. Make sure the test direction and side are notified in the report. Take three measurements along the tearing direction and average these values to obtain specimen thickness. Please note: there is no linear correlation between tearing force and specimen thickness. However, when compare different specimens, the thicknesses should be unified for easy comparison. Prepare the Instrument Turn on the instrument, warm up for at least 90 min, and adjust the output pressure to 0.5—0.55 MPa. Level and balance the instrument as described in Installation section of 2 Instrument. Open the operating software and enter “Preset” interface. Set up the corresponding parameters and click “Save” to confirm. Start the Test Set the pendulum to its latched position. Place the test specimen in specimen holder with the right tearing direction. Press “CLAMP” to grip the specimen. Then cut a slit of 20±0.5 mm with the cutter. Press “TEST” key to release the pendulum. As the specimen is torn up, check if the tearing force lies in between 20%—80% of the pendulum. If not, change the extra weight until the pendulum weight is proper. If the number of specimen layers is changed, modify the parameter “Layers” in “Preset” interface. If the pendulum weight is changed, modify the parameter “Configuration” in “Preset” interface, and rebalance the instrument. If a test is performed improperly, click “Undo” to cancel results of such test. When all tests are finished, save test results and print out test report. 25 Tearing T este r SLY-S1 Change Test Range The test range can be easily changed from 200 gf to 6400 gf by installing different extra weights. Appendix 1 gives several quick means for test range modification. Generally: With the 200 gf basic pendulum, test range can be extended to 800 gf by installing extra weight; With the 1600 gf basic pendulum, test range can be extended to 6400 gf by installing extra weight. Take the change from 200 gf to 400 gf for example: a. Set the pendulum to its latched position and hold it with the pendulum latch; b. Hold the 200 gf balance weight, unscrew the M4X15 bolt, and remove the extra weight; c. Install the 400 gf extra weight by screwing the M4X15 bolt; d. Balance the instrument; e. Perform a bare swing without specimen mounting, and input the maximum angle reached into the red box of “Calibration” interface. Adjust the Cutter and Specimen Holder Replace and Adjust the Cutter If the precut slit of the specimen by the cutter exceeds 20±0.5 mm, the position of cutter should be adjusted. First unscrew two M4X8 bolts as shown in Figure 5, place a calibration ruler at the bottom of the specimen holder, slightly move the cutter to contact the meter tightly, and re-screw the M4X8 bolts. Once the blade of cutter is blunt, it should be replaced simply by unscrewing the M4X8 bolts. 26 Tearing T este r SLY-S1 Left View Front View Figure 5 Adjust the cutter 1&6. Cutter 2.
