9、ze Cut six specimens 38 +/- 1mm diameter from widely distributed locations on the sample, it the design is complex, specimen selection should be agreed with Materials Engineering. The specimens should be taken from not less than 50mm from any selvedge. Cut discs 38 +/- 1mm diameter from the 3mm thic
10、k foam for use as backings for the specimens if unlaminated. If the fabric is laminated, adjust the thickness foam to max 3mm. Test Procedure 1. Mount the conditioned specimens backed with foam discs if unlaminated in the specimen holders using the mounting device on the machine frame. 2. Mount new
11、pieces of abrading material 140mm diameter over the backing felt on the machine tables. 3. Clamp the specimen holders on the moving plate and load the holders to achieve the specified pressure of the specimens of 12 kPa on the abradant. 4. Run the machine for the specified number of cycles, changing
12、 the abradant at 50,000 cycle intervals. 5. Run the machine for 10,000, 20,000, 30,000, 40,000 and 50,000 cycles for insert fabric. Run passenger vehicles to 60,000 cycles for bolster fabric or increase the number of cycles per Material Engineering direction. FORD LABORATORY TEST METHODBN 158-01Prin

14、the fabric must not be significantly removed or changed by wear. Mount all test specimens on a card endorsed with relevant details, for future reference. Report as satisfactory or otherwise the number of cycles to failure. Chemicals, materials, parts and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities.
