MIL-R-52000C(ME)
3.2 Material. Material shall be as specified herein and on the applicable drawings. Materials not specified shall be selected by the contractor and shall be subject to all provisions of this specification (see 6.3).
3.3 Identification marking. The reels shall be identified in accordance with MIL-STD-130.
3.4 Treatment and painting. The reels shall be cleaned, treated, and painted in accordance with MIL-T-704, Type A. Color shall be No. 34087.
3.5 Type I reels. Type I reels shall be as shown on TA13217E7498 and as specified herein.
3.6 Type II reels. Type II reels shall be as shown on TA13217E7499 and as specified herein.
3.7 Workmanship. The reels shall be free from defects or imperfections that might affect their serviceability or appearance.
3.7.1 Steel fabrication. Steel used in the fabrication of the reels shall be free from kinks and sharp bends. The straightening of material shall be done by methods that will not cause injury to the metal. Shearing and clipping shall be done neatly and accurately. Corners shall be square and true. Flame cutting, using a tip suitable for the thickness of metal, may be
employed instead of shearing or sawing. Burned surfaces of flame-cut material shall be g round or machined sufficiently to remove ash and cooling checks.
All bends of a major character shall be made with metal dies and fixtures to insure uniformity of size and shape. Precautions shall be taken to avoid overheating, and heated metal shall be allowed to cool slowly.
3.7.2 Welding. The surfaces of parts to be welded shall be free from rust, scale, paint, grease, mill scale that can be removed by chipping and wire brushing, and other foreign matter. Welds shall transmit stress without permanent deformation or failure when the parts connected by the welds are subjected to proof and service loading. Parts to be joined by fillet welds shall be brought into as close contact as possible and in no event shall be separated by more than 3/16 inch unless appropriate bridging techniques are used. Unless otherwise specified (see 6.2), the welding process used in fabrication of the reels shall be at the option of the contractor.
3.7.3 Welders. Before assigning any welder to manual welding work covered by this specification, the contractor shall provide the contracting officer with certification that the welder has passed qualification tests as prescribed by either of the following listed codes for the type of welding
operations to be performed and that such qualification is effective as defined by the particular code:
AWS D1.1 Structural Welding Code, Section 5, Qualification.
ASME Boiler and Pressure Vessel Code, Section IX, Welding Qualifications.
Contractors who made only horizontal welds need not qualify welders for "all position welding". Subject to approval by the Government, the contractor's standard welder qualification may be substituted in lieu of the above codes provided that the contractor's procedure is equivalent to the above codes. The contractor shall be responsible for determining that automatic welding
equipment operators are capable of producing quality welds in accordance with
AWS or ASME codes.
