Reusable constant force spring force bands CFSB M3262801-10 thru 13 ISOTDS1 thru 4 shield termination bands were evaluated for tensile strength performance as described in SAE AS85049 and AS85049128. The shield bands are employed on shielded wire harness constructions to secure the shield on to the connector accessorybackshell banding platform in order to protect the wires in the bundle from electromagnetic interference EMI. Four sizes of CFSBs M3262801-X, ISOTDS1-X shield termination bands were tested on the eight shell sizes of connector accessories, thus eight test articles. The shield bands were installed on shield braid of suitable width A-A-59569, on shell size A- H of M8504988 backshells, mated to interface connector fixtures. The M8504988 backshells mate to the Mil-Dtl-38999 Series 3 connectors, the most common electrical connector types employed in aerospace applications. The braid retention tensile tests were performed as per AS85049128F, para 2a requirements. All shield bands, configurations and sizes tested in this effort passed tensile test requirements. None of the M3262801-10 thru -13 constant force spring band configuration test articles exhibited shifting, loosening, or other damage after exposure to prescribed linear force. All CFSB test articles passed tensile testing.
