5、ng J365 APR2004 Method of Testing Resistance to Scuffing of Trim Materials RATIONALEChange humidity requirement from 5% to 10% and temperature from 21 to 23 in section 4.1. 1. SCOPE This test can be used to determine the resistance to scuffing of test specimens such as fiberboards, fabrics, vinyl-co

6、ated fabrics, leathers, and similar trim materials. 2. REFERENCES There are no referenced publications specified herein. 3. MATERIALS AND EQUIPMENT REQUIRED 3.1 Abrader Taber Model 5150 or equivalent. 3.2 Specimen Holder 108 mm OD. 3.3 Hold-Down Ring 108 mm OD. 3.4 Rubber Pad 3.5 Clamp Plate 54 mm O

7、D for fabrics, leather, coated fabrics, and similar flexible materials. 32 mm OD for carpets and other floor covering materials. SAE J365 Revised MAY2012 Page 2 of 5 3.6 Scuff Fixture The special scuff fixture head, weight, and other components are shown in Figure 1 and are assembled as shown in Fig

8、ure 2. The scuff fixture is attached to the abrader as shown in Figure 3. The scuff head is held at a 110 degree angle. The vertical centerline of the scuff head is 32 mm from the specimen holder center pin. The tip is centered under the 0.9 kg weight and in a horizontal alignment with the center pi

9、n as shown in Figure 3. NOTE: The attachment bracket shown in Figure 1, detail 8 may be modified for other abrader models, provided the scuff head position is maintained and test results correlate. The scuff head tip shown in Figure 1, detail 11 shall be frequently checked for dimensions and regroun

10、d or replaced if found to deviate from the specified tolerances.

11、evised MAY2012 Page 4 of 5 4. PROCEDURE 4.1 Conditioning The test specimens shall be conditioned for a minimum of 24 h at 23 C 2 C and 50% 10% relative humidity for this test. Unless otherwise specified, the test shall be conducted under the same controlled conditions since a change in relative humi

12、dity and temperature can affect test results. 4.2 Test Samples for Textiles, Coated Fabrics, Leather, or Similar Flexible Materials a. Cut a 6.4 mm hole in the center of a 131 mm diameter specimen. b. Place the specimen on the rubber pad of the specimen holder. c. Place a 54 mm OD clamp plate over t

13、he material and tighten down securely with the clamping nut. d. Press the hold-down ring over the test specimen so that the material is drawn taut over the specimen holder with no wrinkles or bulges. e. Tighten the adjusting screw of the hold-down ring just enough to hold the test specimen but not s

14、o tight as to cause wrinkling or bulging. f. Place the assembled test specimen on the abrading machine and lower the scuff fixture onto the test specimen as shown in Figure 3. g. Scuff for the number of cycles indicated by the engineering specification. 4.3 Test Samples for Fiberboard, Rubber Floor

15、Mats, Carpets, and Other Semirigid Materials a. Cut a 6.4 mm hole in the center of a 106 mm diameter test specimen. b. Place the test specimen on the rubber pad on the specimen holder and tighten down securely with a 32 mm clamp plate and nut. c. Place the hold-down ring over the test specimen, pres

16、s the ring with the fingers, and tighten it. The specimen, when properly secured, shall be free of wrinkles and bulges. d. Place the assembled test specimen on the abrading machine and lower the scuff fixture onto the test specimen as shown in Figure 3. e. Scuff the test specimen for the number of c

17、ycles indicated by the engineering specification. 5. REPORTING Observe and report scuff resistance by comparing the test specimen to an approved master scuff specimen and mounting configuration established by the customer. Report configuration tested.
