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 this specification. 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 by the manufacturer on the primary equipment and all associated equipment to the extent practicable, to demonstrate functionality. The tests may be performed by the Contractor, either by personnel of their service organization directly, or by an independent testing agency.

4.4. At the option of the government, tests may be witnesses by a representative of the receiving activity who shall have the option of sending their technical representative(s) to witness the tests also. The Contractor shall schedule and coordinate the test at origin. At least fifteen days prior to the test, the Contractor shall notify the Government Point of Contact of the scheduled date, time, and location of the test.

4.5. INSPECTION AT DESTINATION

4.5.1. Initial Test And Grooming - The equipment delivered with the system shall be inspected by the Government for mechanical and electrical integrity as follows: All welds shall be inspected for integrity and appearance. Surfaces shall be examined for sharp edges and burrs. Fasteners shall be checked for tightness and if fixed to prevent loosening due to vibration. Paint will be checked for flaking and blistering. Electrical requirements shall be examined for compliance to the National Electrical Code, (NFPA 70/79). The fit of parts shall be observed, with particular reference to the interchangeability of those that are likely to require replacement.

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

4.5.3. Noise Level Test - The Government Industrial Health and Safety Department shall conduct a noise level survey using a certified sound level-measuring instrument. Four random measurements shall be taken at the operator’s work position(s) and at each side and end of the equipment. 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 92 dB (C scale) or less.
