Oil, paint and other foreign substances shall be removed from corrosion-resisting steel surfaces after fabrication. Cleaning shall be

SECTION 05 50 00.20 28 Page 5 done by vapor degreasing or by the use of cleaners of the alkaline, emulsion or solvent type. After the surfaces have been cleaned they shall be given a final rinsing with clean water followed by a 24 hour period during which the surfaces are intermittently wet with clean water and then allowed to dry for the purpose of inspecting the clean surfaces. The surfaces shall be visually inspected for evidence of paint, oil, grease, welding slag, heat treatment scale, iron rust or other forms of contamination. If evidence of foreign substance exist the surface shall be cleaned in accordance with the applicable provisions of ASTM A 380. The proposed method of treatment shall be furnished for approval. After treatment the surfaces shall be visually reinspected. Brushes used to remove foreign substances shall have only stainless steel or nonmetallic bristles. Any contamination occurring subsequent to the initial cleaning shall be removed by one or more of the methods indicated above.

3.2 QUALITY CONTROL SYSTEM

The Contractor/manufacturer shall utilize a quality control system to insure all supplied components meet all specifications and requirements.

The Contractor shall submit Quality Control Reports for Government approval prior to shipment of components.

3.3 TESTING AND TEST REPORTS

The Contractor shall be responsible for all labor, materials, and costs associated with testing. A sample of three (3) percent of all machined components shall be randomly selected from each lot for examination and testing by an independent certified testing laboratory. An independent lab test certification report shall identify component tested, specification, measured property, pass/fail, name of laboratory, equipment used, and submitted for review. Failure of a sample component will result in the rejection of that entire lot. Errors or defects disclosed shall be remedied by the Contractor at no additional cost to the Government and the batch shall be retested. The Contractor shall be responsible for cost of retesting. The following tests shall be performed on each sample.

3.3.1 Crack Test

Items shall be free of cracks as determined by dye penetrant inspection tests.

3.3.2 Hardness Tests

Each sample shall be tested for Brinell hardness and compared to applicable standard.

3.3.3 Surface Roughness Test

Contractor shall test surface requirements by comparing sample to roughness comparison specimen as per ASME B46.1.

3.3.4 Dimensional Tolerance

Dimensional tolerances shall be compared to components specified requirements.

3.4 PROTECTION OF MATERIAL AND WORK

At all times prior to delivery, and as also specified in paragraph 3.5, all

SECTION 05 50 00.20 28 Page 6 materials, supplies, and equipment of every description including property which may be Government-owned and all work performed shall be protected and preserved. All reasonable requests from the Government to enclose or specially protect such property shall be complied with. If, as determined, material, equipment, supplies, and work performed are not adequately protected,such property may be protected by the Government and the cost thereof may be charged to the Contractor or deducted from any payment due.

3.5 PACKAGING, MARKING AND SHIPMENT

(1) All material and articles shall be prepared and loaded for shipment in such manner as to protect them from damage in transit, and any and all damage shall be made good until the equipment is delivered to the Government at the specified delivery point. Where necessary, heavy parts or machines shall be mounted on skids or shall be crated, and any articles or materials that might otherwise be lost shall be boxed or wired in bundles and plainly marked for identification. All parts exceeding two hundred

(200) pounds of gross weight shall be prepared for shipment so that slings for handling by the crane may be readily attached while the parts are on the car or transport truck. Boxed parts, where it is unsafe to attach slings to the box, shall be packed with slings attached to the part, the slings to project through the box or crate so that attachment to the hoisting equipment can be readily made.

(2) No material or equipment shall be shipped until after it has been inspected and accepted for shipment by the Government, or unless inspection of the equipment has been waived in writing. The Government shall be notified at least 15 days in advance as to the expected shipment dates of the equipment.

(3) The Government will accept delivery of materials and equipment when delivered at the specified delivery point in accordance with enclosed provisions.

(4) Each container shall be labeled in such a way that the markings will be permanent and not fade. The labels at a minimum shall contain the following;

(a) Manufacturer

(b) Contract and delivery order number.

(5) As soon as each shipment is made shipping notices shall be submitted on which shall be shown, in addition to the usual data, a description of the article furnished, the item number of the contract schedule to which the article applies, the shipping weight of each item, the number of pieces, the total weight, and if shipped by railroad the car number.
