Instructions for use of the bellows flexibility tester: nxHTextile Testing Instruments, Testing Equipment Manufacturer


1. Take a sample with a length of 1100 mm, vertically on the test platform attached;nxHTextile Testing Instruments, Testing Equipment Manufacturer


Choose a suitable curved support plate, choose oneBacking plate with a radius of curvature of 1500 mm if the inner diameter is ≤90 and select a backing plate with a radius of curvature of 1800 mm if the inner diameter is >90. nxHTextile Testing Instruments, Testing Equipment Manufacturer


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


3. After the specimen is bent to the final position and kept in the bent state for 2 minutes, select a special bellows flexibility gauge suitable for the diameter that tube, insert it into the bellows and watch the plug. Whether the regulations can be successfully met. nxHTextile 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. nxHTextile Testing Instruments, Testing Equipment Manufacturer
