INSTALLATION TEST: INSTALL TWO UNCOILED BANDS AS FOLLOWS: a. A TOTAL OF FOUR BANDS IN EACH CON
16、FIGURATION BEING QUALIFIED WILL BE NECESSARY TO CONDUCT THIS PARTICULAR TEST. SPECIMEN PREPARATION: FOLD TWO OF THE SAME BAND CONFIGURATIONS IN THE CENTER SO THE CENTER FOLD IS AS FLAT AS POSSIBLE. THE TWO REMAINING FLAT BANDS WILL BE USED AS IS. INSERT THE END OF THE FOLDED BAND OPPOSITE OF THE BUC
17、KLE THROUGH THE BUCKLE OF THE FLAT BAND UNTIL THE CENTER FOLD IS POSITIONED WITHIN THE BAND BUCKLE. REPEAT THIS PROCESS UNTIL TWO SETS OF THE BAND SPECIMENS FOR EACH CONFIGURATION BEING QUALIFIED ARE TEST READY. BAND BUCKLE STRENGTH AND STABILITY: ATTACH A 1.00 INCH .125 INCH ROUND MANDREL IN A HORI
18、ZONTAL POSITION TO THE TOP MEMBER OF A SUITABLE PULL TESTER. FORM THE TEST SPECIMEN OVER THE MANDREL AS SUCH SO THAT THE BUCKLE OF THE FLAT BAND IS POSITIONED ON THE TOP OF THE MANDREL. ATTACH ALL OF THE BAND ENDS OPPOSITE OF THE BUCKLE UNDER TEST TO THE LOWER MEMBER FIXTURE OF THE PULL TESTER IN A
19、WAY THAT EQUAL PRESSURE WILL BE APPLIED WHEN THE TWO MEMBERS MOVE IN OPPOSING DIRECTIONS. APPLY A LINEAR FORCE AT A RATE OF 1.00 INCH .25 INCH PER MINUTE UNTIL A 210 POUND MINIMUM LINEAR FORCE IS ACHIEVED FOR THE 1 AND 3 CONFIGURATIONS AND A 105 POUND MINIMUM LINER FORCE IS ACHIEVED FOR THE 5 AND 7
20、CONFIGURATIONS. HOLD FOR 1 MINUTE MINIMUM AND THEN RELEASE THE TENSION. REMOVE THE TEST SPECIMEN FROM THE TEST FIXTURES AND DISCARD THE FOLDED BAND. THE BAND BUCKLE SHALL NOT BE BROKEN, TORN, CRACKED, SEPARATED, OR DISTORTED MORE THAN 20% OF ITS ORIGINAL CONFIGURATION WHEN VISUALLY EXAMINED WITH THE
21、 UNAIDED EYE. b. ATTACH THE APPLICABLE AS81306/*-* TOOL (SEE TABLE 2) TO THE END OF THE BAND. MEASURE THE TOOLS LINEAR PULL FORCE ON THE BAND. THE FORCE SHALL BE 138 POUNDS MINIMUM TO 160 POUNDS MAXIMUM FOR CONFIGURATIONS 1 AND 3 AND 70 POUNDS MINIMUM TO 90 POUNDS MAXIMUM FOR CONFIGURATIONS 5 AND 7.
22、 c. MOUNT THE BAND ON A .20-INCH MANDREL. SLIDE THE BAND THROUGH THE BUCKLE TWO TIMES WHILE PULLING ON THE END WITH A FORCE GAGE. THE FORCE REQUIRED TO SLIDE THE BAND THROUGH THE BUCKLE SHALL NOT EXCEED 7 POUNDS. d. SECURE THE BAND TO A .25-INCH MANDREL WITH THE BAND INSTALLATION TOOL IN ACCORDANCE
23、WITH TABLE 2 AS DEFINED IN THE QUALIFIED MANUFACTURERS TOOL INSTRUCTIONS. EXAMINE THE MANDREL FOR VOIDS BETWEEN THE BAND AND THE MANDREL. THERE SHALL BE NO MORE THAN ONE VOID AREA GREATER THAN .03 INCH WHEN TRANSITIONING FROM THE BUCKLE EDGE TO THE MANDREL. e. EXAMINE THE BAND LOCKING MECHANISM. THE
24、 END OF THE BAND SHALL BE LOCKED OVER THE BUCKLE WITH A 45 MINIMUM BEND. 2. BAND TERMINATION TEST (CONFIGURATION 2 AND 4 ONLY): FOR EACH DASH NUMBER TO BE QUALIFIED, PERFORM THE FOLLOWING TESTS ON TWO BAND SPECIMENS FOR EACH ACCESSORY SHELL SIZE FOR A TOTAL OF SIX SPECIMENS.

FOR CON
36、NECTOR ACCESSORY PART NUMBERS AS85049/82 THROUGH /90, /93, AND /109 THROUGH /117, USE EITHER AS85049/128-1, -2, -3, OR -4 SHIELD BANDS. 4. BAND CONFIGURATIONS -5 THROUGH -8 ARE INTENDED FOR USE IN LOW PROFILE CONFINED FIT APPLICATIONS OTHER THAN STANDARD AS85049 ACCESSORIES. THE USER SHOULD VERIFY T
37、HE BAND CONFIGURATION MEETS THEIR APPLICABLE APPLICATION INSTALLATION REQUIREMENTS. 5. BANDS MUST BE DOUBLE WRAPPED COILDED BEFORE USING THE APPLICABLE INSTALLATION TOOL. FAILURE TO COMPLY WITH THIS METHOD WILL RESULT IN THE BAND NOT MEETING THE PERFORMANCE REQUIREMENTS OF THIS STANDARD. 6. BANDS SH
38、ALL BE TERMINATED ONTO CONNECTOR ACCESSORIES HAVING A SUITABLE BAND PLATFORM DESIGNED FOR THAT PURPOSE. BANDS TERMINATED ON SURFACES OTHER THAN THE INTENDED BAND PLATFORM DESIGN ARE NOT RECOMMENDED FOR USE AND MAY RESULT IN REDUCED PERFORMANCE. SPECIFICATION NOTES 1. REVISION INDICATOR: A CHANGE BAR
