scope:

This standard establishes dimensional limits, design considerations, positioning requirements, and strength requirements for slinging (to include helicopter external air transport (EAT)) and tiedown provisions for lifting or tying down tanks and other tracked vehicles, tactical wheeled vehicles, helicopters, and other military equipment shipped assembled or disassembled in unboxed or uncrated condition and for tying cargo or accessories to such equipment.

This standard excludes external provisions on cargo containers (for example, ISO containers, CONEXes, and MILVANs). It also excludes helicopter and aircraft cargo tiedown provisions.

Although the design of the slinging provisions is covered in this standard, items of equipment requiring helicopter EAT certification must also meet the static lift and helicopter flight-test requirements of MIL-STD-913.

Even though airdrop design criteria for military equipment are specified in MIL-STD-814, Requirements for Tiedown, Suspension, and Extraction Provisions on Military Materiel for Airdrop, equipment must also be transported by surface modes. Therefore, slinging and tiedown provisions for airdrop-designed equipment shall meet both the requirements of this standard and MIL-STD-814.

This standard applies to the following:

a. All new developmental, nondevelopmental, military-adapted commercial items, and reprocurements as noted above.

b. Modified equipment, when the modifications result in changes to slinging or tiedown requirements (for example, provision relocation or item weight increase).

Slinging and tiedown provisions are classified as follows:

Class 1. Slinging provisions. Class 2. Equipment tiedown provisions, including supplementary points of tiedown. Class 3. Multipurpose provisions. Class 4. Cargo tiedown provisions provided within cargo compartments. Class 5. Cargo tiedown provisions provided for cargo platforms of flatbed trailers and flatracks used as demountable truck and trailer beds.

Equipment shall be classified as follows:

Type I. Combat vehicles (for example, armored carriers, self-propelled artillery, tanks, and recovery vehicles). Type II. Tactical and support vehicles (for example, semitrailers, trailers, trucks, materials handling equipment, construction equipment, modified commercial equipment, support vehicles, and other vehicles). Type III. Support vehicles (standard commercial equipment, such as construction equipment, materials handling equipment, trucks, and other vehicles). Type IV. Other military equipment, including helicopters, shipped unboxed or uncrated and lifted separately, each as an individual unit.

Metric equivalents shall conform to FED-STD-376. Conversion tables are in appendix D.

intended Use:

This standard covers the design and testing of slinging, tiedown, and cargo tiedown provisions.
