The first two digits are the last two digits of the calendar year built and the last two letters are the Contractor’s designation, which will be furnished by the Contracting Officer after contract award.

3.4.2 Serial Number. For inspection purposes, the Contractor shall assign each item a unique serial number. The serial number shall be stamped, engraved, or otherwise permanently affixed to each item. The serial number shall consist of ½-inch tall block alphanumeric characters and be clearly visible after the items have been painted.

3.5 Surface Preparation. Prior to surface preparation, all stainless steel parts shall be protected (i.e. taped, masked, etc). All exterior steel surfaces shall be blast cleaned to near-white metal in accordance with NACE Number 2, SSPC-SP-10. Prior to painting, all surfaces shall be free of contaminants such as oil, water, grease, dirt, blasting residue, weld spatter, slag, and flash rust.

3.5.1 Epoxy Repair Compound. After all surfaces have been blasted clean, any weld containing porosity shall be filled with an epoxy repair compound meeting the requirements of MIL-PRF-24176.

3.6 Painting. Prior to painting, all stainless steel parts shall be protected (i.e. taped, masked, etc). The items shall be painted with the coating system outlined below. All painting shall be performed after the items have been cleaned in accordance with paragraph 3.5. All welding, machining, cutting, drilling, forming, or any other operation which would damage the coating system shall be performed prior to painting. The Contractor shall follow the manufacturer’s instructions for correct application of the coating system. In addition, the Contractor shall be responsible for implementing appropriate worker safety procedures for the application of the coating system, and for ensuring that the procedures are strictly followed by the paint applicators.

3.6.1 Epoxy primer. All exterior surfaces shall be coated with an epoxy primer.

The color shall be either haze gray or off-white (manufacturers' standard colors are acceptable). Apply by spraying two coats, 5 mils minimum dry film thickness each. Sharp corners, edges, and other hard-to-coat areas shall be striped before each full coat is applied.

3.7 Documentation.

3.7.1 Quality Assurance Inspection Form. The Contractor shall develop and provide a Quality Assurance Inspection Form (QAIF). The QAIF shall be used to document the inspections and tests performed on every item throughout its fabrication process. The form shall be typewritten on standard (i.e., 8½x11 inch) white paper. Inspection results may be handwritten on the form. The form shall be prepared in the Contractor's format and shall be legible, in English, and suitable for reproduction. The form shall be made available to the Contracting Officer’s Technical Representative (COTR) for review.

3.7.1.1 QAIF Content. At a minimum the QAIF shall include:

a) Item serial number.

b) Date of test or inspection.

c) Test or inspection to be performed (list every test and inspection required by section 4.0).

d) Result of test or inspection.

e) Accept/Reject criteria for each test or inspection.

f) Corrective action taken (if any).

g) Notes.

h) Initials or signatures of Contractor’s test personnel.

3.7.2 Material Certifications. When requested by the COTR, the Contractor shall furnish material certifications, either from the material manufacturers or an independent testing laboratory, to the effect that all of the material described in paragraphs 3.1.1 through 3.1.3 have been tested and found to meet the requirements of the applicable sections of this specification. The material certifications shall be stored by the Contractor for the life of the contract.

3.7.3 Material Inspection and Receiving Report (DHS Form 700). A form DHS-700 shall be used as a certification of product quality assurance, as a packing list, and as a certification of acceptance. The Contractor shall prepare a separate DHS-700 for each shipping lot. Prior to shipment, the DHS-700 must be signed by the COTR.

4. VERIFICATION

4.1 General. The Contractor's quality assurance program shall meet the requirements of ASQ Q9001. However, the Contractor does not have to be Q9001 certified.

4.2 Classification of Inspections. The inspection requirements specified herein are classified as follows:

4.3. First Article Inspection. When first article samples are required, a first article inspection shall be performed by the Contractor and at the Contractor’s facility. The first articles shall meet the requirements of this specification and shall pass all the tests and inspections listed in paragraph 4.6.

4.3.1 First Article Tests and Inspections Notification. The Contractor shall notify the Contracting Officer in writing at least 7 calendar days prior to the scheduled commencement of any inspections and tests required by this specification.

4.3.2 Waiver of First Article Requirements. The Contracting Officer reserves the right to waive all or part of the first article requirements specified herein.

4.3.3 Rejection Criteria. The results of the first article inspection will be reviewed by the Contracting Officer to determine compliance with the requirements of this specification. Failure of any of the tests or inspections described herein will be cause for rejection of the first article. If the first article is rejected, the Contractor will be notified in writing by the Contracting Officer and allowed 14 calendar days to fix or resubmit a new first article. Repair or replacement of the first article shall be by the Contractor at the Contractor's expense.

4.3.4 Authorization to Proceed. Upon successful completion of the first article inspection, the Contracting Officer will provide the Contractor with written authorization to begin fabricating production quantities.

4.3.5 Standardization. Materials, parts, design, and fabrication methods used in the production quantities shall be identical to those used in the first articles, unless otherwise authorized in writing by the Contracting Officer.

4.4 Contractor Production Inspection. The tests and inspections required by this specification are not intended to supplant any controls, examinations, inspections, or tests normally employed by the Contractor to assure product quality. The Contractor shall perform the tests and inspections specified in paragraph 4.6 to ensure conformance to this specification. The Contractor shall provide space, personnel, and test equipment to conduct all inspection and test requirements.

4.5 Coast Guard Production Inspection. The Coast Guard reserves the right to observe, verify, or perform the tests and inspections outlined in paragraph 4.6.

4.6 Tests and Inspections. The following tests and inspections shall be conducted for each first article unit and subsequent production units:

4.6.1 Visual Inspection. Each item shall be visually inspected for quality of workmanship and conformance to this specification and the drawing. The inspection shall include checks of dimensional conformance, mechanical fit, alignment of parts, and marking.

4.6.2 Weld Inspection. All welds shall be visually inspected for quality in accordance with section 6 of AWS D1.1/D1.1M.

4.6.3 Paint Inspection. The Contractor shall provide written proof that each item was cleaned and painted in accordance with paragraphs 3.6 and 3.7. The Contractor shall check the millage at a minimum of six different locations.

4.7 Rejection for Defects. The Coast Guard will reject all items which do not conform to the requirements of this specification. Repair or replacement of the rejected items shall be by the Contractor at the Contractor's expense. All rejected items shall be resubmitted for inspection only when they conform to the requirements of this specification. Resubmitted items shall be identified as such, and shall be kept separate from new items. If defective items are found, no further items will be accepted by the Coast Guard until the Contractor has demonstrated that the defects have been corrected and that the cause of the defects has been eliminated from the production process.

5. PACKAGING.

5.1 Each item is to be packaged in accordance with ASTM D 3951. Associated hardware (items 17 and 18 of drawing 52100-120998 page 1, or 29 and 30 of drawing 52100-120998 page 2) are to be packaged in a sealed plastic bag and inserted into the shipping container.
