2、eat leather and vinyl. This test uses a belt platform to rub duck cloth material against a test specimen under a fixed weight. The belt abrades the sample at 60 cycles per minute. One backward and forward motion of the duck cloth is considered as one cycle. Apparatus and Materials Required 1. Simula
3、ted Seat Wear Tester: (Seat Belt Abrasion Tester) The simulated seat wear tester is modified to hold the test material to the rubbing platform. The counterbalance weight is 2.352 kg +/- 5 g, and a 250 mm stroke length. Sample holders are 40 mm in diameter Source: Schap Specialty Machine, Inc. 17309

7、s unless otherwise specified. Procedure Duck Cloth Belt Preparation 1. Measure and cut the duck cloth to length. (1.1 Meter long) 2. Cut and remove excess material, leaving a tongue of 25 mm x 30 mm at one end. (See Figure 1) 3. Place the tongue into the weight and tighten the two screws. (See Figur
8、e 2) 4. Take the other end of the cloth and fold it back on itself by approximately 150 mm. 5. Thread the double-sided cloth through the back end of the buckle, over the top of the center bar, and back through the buckle and pull through. This will create a large loop. (See Figure 3) 6. Now place th
9、e remainder of the cloth back through the buckle and pull tight. This will secure the loop and stop it from slipping. (See Figure 4) Sample Holder Preparation 1. Ensure the sample holders are clean of all debris / double-sided tape. (See Figure 5) 2. Cut out a blank test specimen 120 mm x 60 mm. (Se
10、e Figure 6) 3. Cover the B surface / back side of the material with double-sided tape 4. Peel the remaining backing of the double-sided tape and stick the material to the holder, keeping the material tight as doing so. Make sure you do not cover the holes on the holder. (See Figure 7) 5. Place the p
11、late over the holes and tighten the screws. 6. Load the sample into the machine, with the tightened screws pointing down. (See Figure 8) Machine Operation & Testing 1. With the sample holder in the machine, take the assembled belt and place the loop around the mandrel and tighten. This will stop the
12、 loop slipping from the mandrel. (See Figure 9) 2. Lay the belt over the material sample and place the weight into the clear tube. (See Figure 10) FORD LABORATORY TEST METHOD BN 163-01 Copyright 2018, Ford Global Technologies, LLC Page 3 of 8 3. Press start on the machine, ensuring the weight does n
13、ot bottom out at the base of the machine. If so, adjust the loop accordingly around the mandrel. 4. Set the machine to the required cycles, and check the stroke arm is set to 250 mm 5. Start the machine, ensuring the machine is running smoothly. 6. After the end of the test cycle, remove the test sp
14、ecimen from the machine and then the holder. Evaluation Lay the test specimen holder on a flat surface and examine the A surface of leather / vinyl for wear through. Report the result as evidence of wear through or no wear through, see Figures 11 and 12 for examples. Notes :- This method was written
