Section 2 DESIGN SPECIFICATIONS FOR ACCOMMODATING 24 X 6 REELS 2.1 PACKAGING SYSTEM The mag
24、net wire packaging system shall be designed to be returnable and reusable, capable of securing reels placed on end, flange to flange on the pallet. 2.2 PALLETS 2.2.1 General The design of a single row system shall accommodate one to four reels having dimensions in accordance with NEMA MW 1000. A sys
25、tem accommodating a single layer of pallets arranged in a double row shall accommodate five to eight reels. 2.2.2 Dimensions The length and width shall be sufficient for compliance with 2.2.1. The height shall be nominally 6.25 in. 2.2.3 Configuration The surface where reels rest shall have a design
26、 that provides a positive locating system that limits movement of the reels during shipment, shall be designed to allow for secure stacking of pallets among themselves, and shall include a means of guiding banding straps. 2.2.4 Handling Pallets shall be capable of two-way entry by mechanized pallet
27、handling equipment, parallel with the flange orientation. 2.3 STRENGTH 2.3.1 Load 2.3.1.1 Single Row Loading Pallets supporting single row loading shall be capable of supporting a static load not less than 1,500 lb. 2.3.1.2 Double Row Loading Pallets supporting a single layer of reels in a double-ro
28、w arrangement shall be capable of supporting a static load not less than 2,500 lb. Pallets supporting multiple layers of reels in a double-row arrangement shall be capable of supporting a stacked static load of 15,000 lb. 2.3.2 Storage The design shall allow for pallets to be stored in a rack struct
29、ure, constructed with rack beams only, with a maximum of 38 in. between beams, and no decking. MW 780-2005 Page 3 Copyright 2005 by the National Electrical Manufacturers Association. Section 3 MATERIALS 3.1 GENERAL Plastic materials have been generally planned as the systems material, however materi
30、als used for magnet wire packaging systems shall not be limited to plastics. 3.2 CHARACTERISTICS The pallet material shall be recyclable and present no potential material conflict with magnet wire reels, wire, or wire insulation.

31、rers Association. Section 4 MARKING 4.1 MATERIAL IDENTIFICATION The pallet shall be coded with the chasing arrows generally used as a code for signifying that a material is recyclable, as well as the recycling material number code of 1 through 7, and the material letters to indicate the material typ
32、e (e.g. PS, for polystyrene). 4.2 MANUFACTURER IDENTIFICATION All parts of a magnet wire packaging system shall have available space for either the individual wire manufacturers company logo or other form of identification such as a color strip and/or mark of some distinctive nature. Two spaces shall be provided (one on each of two opposing sides) for bar code labeling approximately 2 x 3 in. in size.
