If the surface of the cork become smooth replace it with new cork liner 2. After replacing, run the box with empty tubes for 200 hours NED University Of Engineering & 5 Technology  APPARATUS FOR FIXING THE FABRIC ON TO THE TUBES POLY URETHENE TUBES MOUNTING OF SPECIMEN NED University Of Engineering & 6 Technology  CONDITIONING REQUIREMENTS Conditioned the fabric sample in standard atmosphere as per ISO 139 (20 to 24 hours) at Temperature = 20 +/- 2 °C Relative humidity = 65 +/- 2% NED University Of Engineering & 7 Technology  SPECIMEN SIZE AND PREPARATION CUTTING OUT: From the sample, cut four test specimens, each 125 mm x 125 mm (2 for warp 2 for weft). On each test specimen mark the back of the fabric and the length direction, Where a fabric has no visible face, test both sides. An additional specimen of 125 mm x 125 mm is required for assessment. NOTE: Test specimen should be randomly placed with none of the test specimens having common warp or weft threads. NED University Of Engineering & 8 Technology  SPECIMEN SIZE AND PREPARATION TEST SPECIMENS PREPARATION: 1. Take a specimens and fold with its face, if visible, inward and with the machine direction running in the direction of the fold. 2. Sew 12 mm from the cut edges to form a tube, using a stitch density such that a balanced seam is produced. After stitching turned inside out 3. Prepare the other three specimens similarly with the cross direction ruining in the direction of the fold. NED University Of Engineering & 9 Technology  SPECIMEN SIZE AND PREPARATION MOUNTING OF THE SPECIMEN: Turn each specimen inside out, so that the fabric face forms the outside of a tube, and cut 6 mm of each end of the fabric tube to remove any sewing distort ion. Using the mounting jig , mount one specimen on each polyurethane specimen tube so that the specimen ends are an equal distance in from the ends of the polyurethane specimen tube Ensure that the seamed portion lies as flat as possible. Apply self-adhesive PVC tape around each of the specimen, so that the tape fixes the specimen on to the tube and leaves 6 mm of the polyurethane specimen tube exposed. The length of tape on each end of the specimen shall not exceed a length of approximately 1,5 times the circumference of the tube.
