4. QUALITY ASSURANCE PROVISIONS

4.1 RESPONSIBILITY FOR INSPECTION - The Contractor shall be responsible for the performance of all inspection requirements (examinations and tests) as specified herein. The Contractor may use his own facility or any other facility suitable for the performance of the inspection requirements specified herein. The Government reserves the right to perform any of the inspections set forth in this specification, where such inspections are deemed necessary to assure supplies and services conform to the prescribed requirements.

4.2 RESPONSIBILITY FOR COMPLIANCE - All items shall meet all requirements of sections 3 and 5. The inspection(s) 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 inspections, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements; however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material.

4.3 BASIC PERFORMANCE TESTS - Basic performance tests shall be conducted on the primary equipment and all associated equipment to the extent practicable, to demonstrate functionality. The tests may be performed by the Manufacturer, either by personnel of their service organization directly, or by an independent testing agency.

4.4 INSPECTION AT DESTINATION

· All welds shall be inspected for integrity and appearance.

· Surfaces shall be examined for sharp edges and burrs.

· Fasteners shall be checked for tightness.

· Paint will be checked for flaking and blistering.

· The fit of parts shall be observed, with particular reference to the interchangeability of those, which are likely to require replacement.

Note: Faults will be duly recorded and presented to the contractor for rectification.

4.4.2 Operational Tests - Upon satisfactory completion of the tests above, the equipment shall be setup by the government for an operational test. The unit shall be exercised to the extent necessary to prove proper operation in accordance with specification requirements. The system shall function, without failure, for the duration of this test period. If a failure occurs during operational testing, the contractor shall be duly notified for rectification and upon repair the tests shall be restarted from the first test. Three failures without completion of the operational tests shall be considered cause for rejection of the system. For the purpose of this test, a “failure” is defined as any equipment malfunction, which requires remedial action to restore the system to full operation in accordance with contract specifications.

4.4.3 Noise Level Test - The Government Industrial Health and Safety Department shall conduct a noise level survey using a certified sound level-measuring instrument. The noise level test shall be measured 3 feet away from the machine with three measurements on each side and end of the equipment. Readings will be taken 1 foot off the ground and any point up to 8 feet off the ground. The vacuum shall have 25 feet of 5 inch vacuum recovery hose attached during the test. The vacuum noise shall be tested at free flow and 26 inches Hg. For each measurement, the microphone shall be located on a straight line which is perpendicular to the surface/corner being measured and at a height corresponding to the point of the highest noise level emitted from the surface/corner at the herein specified location or distance from the equipment. Each sample shall be 84 dB (A scale) or less and 91 dB (C scale) or less.
