Unlessotherwise

7、specified (see 6.2), all testing shall be performed on the same Type II CBC. The presence of any visual defect, anydimension not within the specified tolerance, or failure of any test shall be cause for rejection of the first article.4.2.2 Comparison Sample Inspection When a comparison sample inspec

8、tion is required (see 6.2), it shall be inspected andtested as specified in 4.2.1.4.2.3 Quality Conformance InspectionUnless otherwise specified, sampling for inspection shall be performed in accordancewith ANSI/ASQC Z1.4-2003.4.2.3.1 Component and Material InspectionIn accordance with 4.1, componen

9、ts and materials shall be inspected inaccordance with all the requirements of referenced documents unless otherwise excluded, amended, modified, or qualified in thisspecification or applicable purchase document.4.2.3.2 End Item Visual Examination The end item shall be examined for the defects listed

10、 in Table 3. The lot size shall beexpressed in units of one Type II CBC. The sample unit shall be one Type II CBC. The inspection level shall be II and the AQL,expressed in terms of defects per hundred units, shall be 4.0 for major defects and 6.5 for total (major and minor combined) defects.4.2.3.3

11、 End Item Dimensional ExaminationThe end item shall be examined for conformance to dimensions specified. Anydimension not within the specified tolerance shall be classified as a defect. The lot size shall be expressed in units of one shelter.The sample unit shall be one shelter. The inspection level

12、 shall be II and the AQL, expressed in terms of defects per hundred units,shall be 4.0.4.3 Verification Methods:4.3.1 WeightCompliance with 3.2.1 shall be determined by weighing the Type II CBC and its mounting hardware. The scaleused shall have a one (1) 1 lb or less graduation and shall have an ac

13、curacy within plus or minus one (1)1 lb. The scale shall havea current calibration traceable to the National Institute for Standards and Technology. Failure to meet the requirements of 3.4.1 shallconstitute failure of this test.4.3.2 Tailgate OperationWith the Type II CBC mounted on its carrier, the

14、 carriers tailgate shall be operated (that is, openedand then closed). Failure to meet the requirements of 3.2.2 shall constitute failure of this test.4.3.3 BlackoutThe Type II CBC/carrier combination shall be located at the center of a circle of radius 300 meteres, on levelground, in an area with a

15、 wooded or hilly background (that is, the silhouette should not be above the horizon). There shall be nosignificant obstructions (higher than 18 in. (46 cm) between observers located on the circumference of the circle and the Type IICBC/carrier combination. Testing will be conducted in hours of dark

16、ness between early evening nautical twilight (EENT) andbeginning morning nautical twilight (BMNT) on a moonless night. A 100-watt unshielded white light bulb, rated at no less than17 Lumens per Watt, A-19 style, shall be located inside the Type II CBC and suspended approximately one (1) 1 ft from th

17、e topand center of the Type II CBC with all doors, ports, and vents closed. The light shall be turned on and off at random intervals fora period of 5 minutes.min. Eight observers, positioned along the circumference of the circle at 45 degree intervals starting fromthe forward longitudinal axis of th

18、e Type II CBC/carrier combination, shall record any light detected during the test period. Failureto meet the requirements of 3.2.3 shall constitute failure of this test.4.3.4 InterchangeabilityCompliance with 3.2.4 shall be determined by selecting two Type II CBCs from the production lotof complete

19、d Type II CBCs. All removable parts shall be interchanged between Type II CBCs selected. The interchange shall beaccomplished by removing the fasteners, interchanging the parts and reinstalling the fasteners. Inability to interchange the partsin accordance with 3.2.4 shall constitute failure of this

20、 test.4.3.5 MountingUsing only the hardware provided with the Type II CBC, the Type II CBC shall undergo 10 cycles ofE2463 115installation and removal (see Table 2) from its carrier in accordance with its manual. The CBC and its carrier shall be inspectedafter each cycle for damage or degradation. F

21、ailure to meet the requirements of 3.2.5 shall constitute failure of this test.4.3.6 ToxicityDemonstrate the Type II CBC does not produce toxic exposures by meeting ACGIH Threshold Limit ValuesThreshold Limit Values for materials used in the Type II CBCs construction.
