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.
