4.2. RESPONSIBILITY FOR COMPLIANCE - All items shall meet the requirements of this specification. The inspections set forth in this specification shall become part of the Contractor's overall inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the Contractor of the responsibility of assuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling for quality conformance does not authorize submission of known defective material (either indicated or actual) nor does it commit the government to acceptance of defective material.

4.6.2. If, during assembly any noises, rubbing, or grinding are heard or felt indicating potential problems the entire test procedure shall be repeated after replacement of the failed part(s).

4.6.3. Any flaws detected in materials and/or workmanship, which reduces the usefulness of the turbochargers to the Coast Guard, shall be resolved before completing any further work.

4.6.4. Any unusual noises or other non-compliances, as determined by the Coast Guard Inspector, will require re-testing and shall be cause for failure.

4.7. TEST AND INSPECTION REPORTS - One copy of any inspection or test report approved for use from submittal shall be sent to the Contracting Officer for approval. A copy shall also be given to the Coast Guard Quality Assurance Representative upon his arrival at the Contractor's facility.

5.0. PRESERVATION, PACKING, & MARKING

5.1. PRESERVATION - An overhauled Turbocharger is typically intended for long term warehouse storage and not for immediate installation. Therefore, it is critical that the Contractor ensure that the overhauled Turbocharger undergo the following preservation requirements.

5.1.1. INTERNAL: Internal surfaces shall be spray/fogged and drained with Code 10, Grade 30 preservative as specified by MIL-STD-2073-1E APPENDIX J, TABLE J.III.

5.1.2. EXTERNAL: Unpainted surfaces shall be coated with Code 19, Grade 4, corrosion preventative as specified by MIL-STD-2073-1E APPENDIX J, TABLE J.III.

a. All fittings or openings that would allow foreign material to enter the unit shall be plugged or capped.

1. A soft gasket shall be placed between the flanges and the bolted on cap. (See Appendix Figure 2.)

5.2. PACKING and PACKAGING– After preservation, each turbocharger shall be individually packed and packaged in its own enclosed wooden container in accordance with ASTM D3951, the following detailed requirements and as depicted in Appendix D.

5.2.1. The wooden container shall provide protection to the Turbocharger during multiple shipments and handling by common carrier.

5.2.2. The crate skid base shall be constructed using three (3) each four inch by four inch (4” x 4”) solid construction wooden beams to facilitate forks for lifting. The crate base wooden decking shall be constructed of two inch by six inch (2” x 6”) solid wood planking. The wooden plank decking shall be screwed to the 4” x 4” skid base using decking screws.

5.2.3. An angle iron bracket shall be fabricated (see Appendix D, Figure 1) so as to accommodate the assembled Turbocharger and allow it to be securely bolted to the angle iron bracket.

5.2.4. The angle iron bracket shall be through bolted to the skid base.

5.2.5. Prior to the Turbocharger being attached to the angle iron bracket on the skid base, it shall be placed inside 8 mil thick, heat shrink plastic. (Appendix D, Figure 3)

5.2.6. After mounting and bolting the Turbocharger to the angle iron bracket on the skid base with machine bolts using existing mounting holes in the Turbocharger, the area where the machine bolts penetrate the heat shrink plastic shall be sealed using compatible RTV sealant. (Appendix D, Figure 4)

5.2.7. Prior to sealing the heat shrink plastic, 64 ounces (units) of desiccant shall be placed inside the plastic.

5.2.8. A second layer of 8 mil thick heat shrink plastic shall be place over the Turbocharger and mounting bracket and then shrunk using a suitable heating device. (Appendix, Figure 5)

5.2.9. The container cover shall be constructed using ½ inch plywood framed on the inside with 2” x 4” solid wood framing. Wood decking screws shall be used to attach the plywood to the framing. Using OSB or particle board is not acceptable and wood screws directly into the plywood are not acceptable.

5.2.10. After the container cover is properly constructed, all corners and edges shall be protected using 1 ½ inch x 1/16 inch thick angle as depicted in Appendix D, Figure 6. The angle shall be attached using wood deck screws into the 2” x 4” solid wood internal framing.

5.2.11. The container cover shall be appropriately sized so as to fit the enclosed Turbocharger but not oversized so as to squander storage and shipping space.

5.2.12. Lifting handles shall be installed as depicted in Appendix D, Figure 7 to facilitate the installation and removal of the container cover. There shall be an appropriately sized 2” x 4” solid wood framing placed strategically so the lifting handle screws are threaded into the solid wood framing and not just the plywood cover.

5.2.13. The plywood cover shall be attached to the skid base using lag bolts that thread into the 4” x 4” solid wood beams that are a part of the skid base. The lag bolt holes shall be predrilled to prevent the wood beams from splitting.

5.2.14. The lag bolts attaching the cover to the skid base shall have a two inch square of red paint around the bolts so the end user can easily indentify the proper bolts to remove to gain access to the Turbocharger.

5.2.15. Each turbo charger shall be supplied with a gasket installation kit to facilitate installation using the correct gaskets and seals. This kit shall be made part of the package. The contents shall be in a plastic bag and placed in cardboard and clearly marked “installation gasket kit”.

5.3. MARKING - Each preserved and packed Turbocharger shall be marked in the upper left-hand side of the two longest sides, (two opposite sides if square).

5.3.1. The markings shall be made with machine-made stencils; the lettering / numbering shall be 1” high, in permanent black printed characters on a highly contrasting “white painted” background.

5.3.2. Bar Coding – A Bar Code label shall be attached to each turbocharger shipping container prior to shipment from the Contractor’s facility.

a. All bar coded labels shall be in accordance with ELC specification D-000-100.

1. The actual label shall be Type "V", Grade "2", Style "2", Composition "b" with plastic laminate.

2. Each label shall contain encoded data for the Stock Number.

a The marking required in 5.3 can be applied separately or as part of the Bar Code Label.

5.3.3. The marking shall consist of the following:
