本文件规定了设计标准和测试方法，足以保证由钢丝绳制成的货物约束吊索组件的极限强度和运行可靠性，其额定极限载荷能力为22.25 kN（5000 lbf），航空业可用于在飞行期间约束民用运输机，包括: -？装载并系在适航批准的空运货盘上的货物，其本身被限制在飞机下层甲板、主甲板或上层甲板货物系统中，并符合ISO？8097（NAS？3610）或ISO？21100的要求，或 -？非单元化的单个货物，或放置在未受限制的（“浮动”）托盘上的货物，放入飞机的下层甲板、主甲板或上层甲板集装箱货舱，被限制在飞机结构连接（系紧）点上。 定义了两种类型的钢丝绳约束吊索: a） a型:可调长度约束吊索组件，包括张力保持装置和连接到钢丝绳端眼的终端配件； b） b型:与a型电缆一起使用的固定长度约束吊索延长件；延伸部分通常通过眼在两端终止，无需额外配件，并可通过挂钩或钩环连接。 本文件中规定的电缆仅用于飞机上的约束目的，而不是用作吊索。

This document specifies the design criteria and testing methods adequate to guarantee the ultimate strength and operational dependability of cargo restraint sling assemblies made of steel wire rope, with a 22,25？kN (5？000？lbf) rated ultimate load capability, as can be used by the airline industry in order to restrain on board civil transport aircraft during flight, including the following: —？cargo loaded and tied down onto airworthiness approved air cargo pallets, themselves restrained into aircraft lower deck, main deck or upper deck cargo systems and meeting the requirements of ISO？8097 (NAS？3610) or ISO？21100, or —？non-unitized individual pieces of cargo, or pieces of cargo placed onto an unrestrained ("floating") pallet into either lower deck, main deck or upper deck containerized cargo compartments of an aircraft, to be restrained onto aircraft structure attachment (tie-down) points. Two types of wire rope restraint slings are defined: a) type？A: adjustable length restraint sling assemblies, including a tension retaining device and termination fittings attached to the wire rope end eyes; b) type？B: fixed length restraint sling extensions, to be used in conjunction with a type？A cable; extensions are usually terminated at both ends by eyes, without additional fittings, and can be attached through hooks or shackles. The cables specified in this document are intended exclusively for restraint purposes on board aircraft, and not for use as lifting slings.
