Instructions for use of the bellows -Flexibility tester:qoKTextile Testing Instruments, Testing Equipment Manufacturer


1. Fix a sample with a length of 1100mm vertically on the test platform.qoKTextile Testing Instruments, Testing Equipment Manufacturer


Choose a suitable curved support plate, chooseUse a backing plate with a radius of curvature of 1500 mm for an inner diameter ≤ 90 and a backing plate with a radius of curvature of 1800 mm for an inner diameter > 90. qoKTextile Testing Instruments, Testing Equipment Manufacturer


2. In the area 900 mm above the specimen, slowly bend the specimen to both sides by hand into the arch template position. Bend left and right back and forth five times. qoKTextile Testing Instruments, Testing Equipment Manufacturer


3. When the sample bends to the final position and stays in the bent state for 2 minutes, select a special bellows flexibility gauge suitable for the pipe diameter, insert it into the bellows and observe whether the gauge can pass smoothly. qoKTextile Testing Instruments, Testing Equipment Manufacturer


If the special plug gauge can pass through without any problems, the flexibility of the plastic bellows is qualified. On the contrary, it is not a qualifying product. qoKTextile Testing Instruments, Testing Equipment Manufacturer
