This is an engineering drawing specification for a steel storage container manufactured for Portsmouth Naval Shipyard. The drawing RF-2203 (document number 2370A000389) establishes detailed design and manufacturing requirements for a rectangular steel container with dimensions of approximately 20.75" x 18.00" x 36.125" (height), with a rated capacity of 560 lbs for lifting via the safety hoist ring and 2,400 lbs per side via two lifting lugs. The container assembly consists of ten components including a steel base, four walls, one flange, one top, two lift lugs, four security tabs, one rubber silicone gasket, twelve washers, and twelve closure bolts.

The specification requires all steel components conform to ASTM A36 material standards with a 125 RA finish unless otherwise specified. Manufacturing requirements include chamfering sharp edges to minimum 0.03", breaking all weld spatter, and welding operations performed by qualified welders per AWS D1.1/D1.1M with minimum 45-degree bevel angles and visual inspection per AWS standards. Magnetic particle testing (MT) per MIL-STD-2035 Class 3 acceptance criteria is required for all specified welds. Painting requires two coats of Amercoat 235 paint per MIL-PRF-23236, with the first coat in a color other than black and the top coat in black. The drawing specifies two critical load tests: a safety hoist ring proof test at 2,500 lbs working load limit using torque-based procedures, and lifting lug load testing at 7,775 lbs (150% load) to 8,164 lbs (155% load) with visual and MT inspection requirements. Final assembly requires documentation of empty container weight, and permanent marking must include SPS capacity, load test/NDT due dates, unloaded weight, and maximum loaded weight specifications.
