REQUIIEMENTS

3.1

GENERAL

3.1.1 Requirements of General Packaging Standard NAS 850 are part of this standard except as noted herein.

3.1.2 Packaging and packing of electrical harness and cable assemblies in straight lengths is preferred. Harness and cable assemblies may be coiled when necessary for reduction of cube, case of handling and distribution of packed weight.

3.1.3 Minimum coil diameter and uniform configuration shall be observed whenever it is necessary to coil harness or cable assemblies. Kinking shall not be permitted under any circumstances.

3.1.4 Preformed items shall be packaged to ensure that the design configuration is retained when specified on the Engineering drawing.

3.1.5 No coil shall have an inside diameter of less than 10 times the item's largest cross‐section diameter. Minimum inside coil diameter for solid metal jacketed coaxial (e.g. aljak, heliax, spir‐o‐line) shall be 36 inches re‐ gardless of item diameter.

CAUTION: ENSURE THAT WIRES ARE NOT STRAINED AT SPLICED AREAS OR PROCESSED

TERMINATION POINTS WHEN COILING.

3.1.6 Processed terminations, couplings, fittings, etc., shall conform to the configurationand not be forced into the coil void space.

3.2

UNPTPACKAGING

3.2.1 The quantity per unit package shall be as follows, unless otherwise specified by the procurement document:

One (1)each (length, type or size) 3.2,2 When coiling is employed, items shall be coiled in successive turns or layers in uniform, compact configura‐ tions on spools or reels, or coiled and securedwithin suitablecontainers.

3.2.3 Coiled assemblies shall be adequately secured by blocking, bracing, cushioning, a€fking to core spools, and/or by placing tape or strapping equaiiyspaced around the circumference of the coil to ensure that the configuration of the coiled layers is maintained. Spools and reels (wood, steel or fiber) are acceptable if their drum diameters meet the minimum coil diameter @end radius) requirements and if they will accommodate the bu& and weight of the item. Steel strapping shall not be used. When used, the flanges of any spool or reel shall extend beyond the coiled unit.

3.2.4 Heliax cable shallbe coiled on a €ked reel within a container. Bloclcing and bracing shall not be used for heliax cable.

NOTE:

Steel spools shall not be used with solid metal‐jacketed coaxial cables.

3.2.5 All unit openings shall be closed with protective plugs or caps. ARernate methods which provide the intended protection are acceptable.

3.2.6 Ali cable harness terminations shall be wrapped or bagged with plastic material taped or tied inplace, then overwrapped with cushioning material.

3.3

INTERMEDIATE PACKAGING

3.3,l Intermediate packaging shall be in accordance with applicable requirements of

NAS 850

3.4

PACKING

3.4.1 Exterior packing shall be in accordance with applicable requirements of NAS 850.
