航空货物.约束吊索.第1部分：设计和试验

[中文适用范围]： 本文件规定了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操作可靠性的设计标准和测试方法，其额定极限载荷能力为 22,25 kN (5000 lbf)，可供使用航空业为了在飞行期间将民用运输飞机限制在机上，包括以下内容： ——装载并绑扎在适航性批准的航空货运托盘上的货物，其本身限制在飞机下层甲板、主甲板或上层甲板货物系统中，并满足以下要求： ——非组合的单件货物，或放置在飞机下层甲板、主甲板或上层甲板集装箱货舱中的无约束（“浮动”）托盘上的货物，将被限制在飞机结构附件上（系带）下）点。 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端接配件； b) B 型：固定长度约束吊带延长件，与 A 型缆索配合使用；延伸件通常在两端通过孔眼终止，无需额外的配件，并且可以通过钩子或卸扣连接。 本文件中指定的电缆专门用于飞机上的约束目的，而不是用作起重吊索。 [外文原描述]： 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.
