    2、ty of the individual components used in the assembly. Apparatus Required Tensile Machine Shall meet the requirements of ASTM D 76. Oven Mechanical convection oven capable of maintaining 102 +/- 3 OC. Fade -0meter Operated as described in SAE J 1885 Fluorescent Sunlamp Cabinet See FLTM BO 11 5-01 for

    3、 details of the cabinet. Cold Box Must be capable of being maintained at - 18 +/- 1 OC. W Flex Tester As described in FLTM BN 102-02. Conditioning and Test Conditions All test values indicated herein are based on material conditioned in a controlled atmosphere of 23 +/- 2 OC and 50 +/- 5 % relative

    4、humidity for not less than 24 h prior to testing and tested under the same conditions unless otherwise specified. I Date I Action I Revisions I Copynght02001, Ford Global Technologies, Inc FORD LABORATORY TEST METHOD BN 013-03 Procedure Test Procedure “A“ This procedure shall be used to determine if

    5、 critical areas of the cover material have been properly processed during the manufacturing operations employed in unitizing a specific seat cover assembly. Note: Critical areas are defined as bond lines, embossments, sew lines and formed or shaped areas. Test Procedure “B“ This procedure is used to

    6、 evaluate unitized seat cover components under accelerated aging conditions to determine the compatibility of the assembly components. Conditioning of Samples All samples shall be conditioned at 23 +/- 2 OC and 50 +/- 5 % relative humidity for at least 24 h prior to testing. Test Procedure “A“ 1. Cu

    7、t samples from the critical areas of the unitized seat assembly and separate the cover stock from the other components except in the critical areas to be tested such as bond lines, sew lines, etc. Cut samples from non-critical areas and separate cover stock from other components to test the virgin a

    8、rea of the cover stock when required. 2. Determine tensile strength as outlined in ASTM D 1682. 3. If test results are below the minimum tensile specified by the applicable Engineering material specifications for bonded, embossed, formed, shaped or sewn area, the assembly shall be rejected for impro

    9、per processing, provided that the virgin areas of the cover material meet the specifications. (If the virgin areas do not meet specification, then the quality of the processing cannot be verified.) Test Procedure “B“ This test is conducted after the assembly has been approved when evaluated by Test

    10、Procedure “A“. 1. Cut three test specimens 65 x 80 mm from the bonded seat assembly and subject one specimen to aging test “a“, the second to “b“ and the third to “c“. The samples shall be cut to represent all typical bonded or sewn areas. Aging Test “a“ Age a test specimen for seven days at 102 +/-

    11、 3 OC. Aging Test “b“ Expose a test specimen for 200 h in a fluorescent sunlamp cabinet at 63 +/- 3 OC at 300 mm from the lamps. Page 2 of 3 Copynght02001, Ford Global Technologies, Inc FORD LABORATORY TEST METHOD BN 013-03 Aging Test “c“ 1. Expose a test specimen for 225.6 kJ/m2 in a Xenon Fade-ome

    12、ter operated as described in SAE J 1885. 2. Remove the cover stock from the test specimens retaining the thread, if present, and the bonding pad in the bonded area. 3. Mount the test specimens on a W Flex Tester, as described in FLTM BN 102-02, and place the tester with the mounted specimens in a co

    13、ld box at 18 +/- 1 OC. 4. Run the specimen for the specified number of test cycles indicated by the Engineering material specification. 5. Examine the cover stock after the cold flex tests and report any staining, cracking of cover material or other adverse effects as specified by the Engineering material specification. 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.
