MIL-DTL-81306B
4.5.6 Tensile strength. The straps shall be subjected to and comply with the tensile test
requirement of SAE-AS23190.
4.5.7 Low temperature performance. The tiedown strap tool, four of each size cable strap,
and wire bundle, fabricated in accordance with SAE-AS23190, shall be maintained at a
temperature of -15 º ± 2 ºC for a period of one hour. The tiedown strap shall then be installed to
its wire bundle while at this temperature. The tool shall continue to function during and after this
test. The test straps shall comply with the requirements of SAE-AS23190. It is permissible for a
change in the tightness of the bundle if the temperature of the bundle is allowed to return to
normal environmental conditions.
4.5.8 Corrosion. One tool shall be subjected to a salt spray (corrosion) test in accordance
with MIL-STD-202, Method 101, Condition A. The tool shall then be dried. After the tool is
dry, it shall comply with 4.5.6 and 4.5.7 and shall not exhibit basis metal on plated or treated
parts. White or black residue is permitted as long as the tool function is not impaired.
4.5.9 Life cycle. The tool shall withstand a total of 15,000 tension and cut cycles.
Unstressed polyamide (nylon) stock conforming to ASTM D4066, type PA111 or metal stock
conforming to ASTM A666, type 304, 304, or 316 shall be used in lieu of straps. The stock shall
have the dimensions specified in table I. The nylon or metal stock shall be fed to the tool in such
a manner that the action of the gripping device, when the tool is operated, shall exert tension
corresponding to the maximum tool tension setting for the strap size being tested. A cycle shall
consist of closing the tool through the cutting position and returning the handle to the full open
position. After each 2500 cycles, the tool shall be tested by installing the straps as specified in
table I around a bundle of wires fabricated in accordance with SAE-AS23190. At no time during
this test shall the compression force, required to be exerted on the handles of the tool at a point 1
+ 1/8-inch from the extremity of the handles, exceed that shown in table I.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified
in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-
house contractor personnel, these personnel need to contact the responsible packaging activity to
ascertain packaging requirements. Packaging requirements are maintained by the Inventory
Control Point's packaging activities within the Military Service or Defense Agency, or within the
military service's system commands. Packaging data retrieval is available from the
managing Military Department's or Defense Agency's automated packaging files, CD-ROM
products, or by contacting the responsible packaging activity.
