About this file
This is a fabrication details document specifying requirements for tungsten-impregnated polymer shielding for the Department of the Navy Naval Sea Systems Command. The requirement is for 3 units of shielding material that must be composed of a homogenous matrix of tungsten powder and silicone rubber, with approximately 90% tungsten by weight. The material must meet specific technical requirements including a minimum density of 7 g/cc, a tenth value thickness equal to or better than 2.09 inches, and must be non-yellow in color.
The material must undergo testing for detrimental materials including bromides, chlorides, fluorides, sulfur (all at 250 PPM leachable limit), and mercury (10 PPM limit) per MIL-STD-2041 Rev E. The shielding must be defect-free and properly packaged on pallets not exceeding 3000 pounds. Vendor must provide certified test reports verifying compliance with all specifications, signed by Quality Assurance, and traceable to the purchase contract. Partial shipments are permitted.

E. Testing for detrimental materials is required. Quantitative test reports shall be provided as evidence that all materials used have been tested in accordance with Appendix A, Section A.6 of MIL-STD-2041 Rev E, Notice 1 Control of Detrimental Materials, and that the materials do not exceed the following limits:
BROMIDES 250 PPM (LEACHABLE)* CHLORIDES 250 PPM (LEACHABLE)* FLUORIDES 250 PPM (LEACHABLE)* SULFUR 250 PPM (LEACHABLE)* MERCURY SHALL NOT EXCEED 10 PPM
*At the option of the vendor, total levels of each halogen and sulfur may be determined in lieu of water-leachable levels per MIL-STD-2041 Rev E, Notice 1.
If the materials have been satisfactorily tested within the last four years, a copy of those test reports and a statement by the manufacturer that there has been no changes in the formulation or manufacturing process shall be submitted and is acceptable in lieu of performing additional detrimental material analyses.
F. Shielding shall be clean, well finished and free from foreign matter, cracks, holes, or other defects that may affect appearance or serviceability.
G. Shielding shall be appropriately palletized and packaged to provide adequate protection for shipping and storing. Each shipping pallet shall have a maximum loaded weight of not more than 3000 pounds. The loaded pallet shall comply with all D.O.T. Safety regulations. Partial shipments are acceptable.
H. Vendor shall provide Certified Test Reports that provide quantitative data to verify that the materials provided meet the requirements of Table (2), Attributes (1) through (3). Test Reports shall be signed and dated by the vendor’s Quality Assurance rep. and shall be traceable to the purchase contract under which the material is provided.
