Since tolerance of test equipment is normally considered to be within 10% of the product tolerance for which it is intended, this inherent error in the test equipment design must be c

39、onsidered as part of the 4.5.2.2 Contractor Design. The contractor shall design and 6 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-T-63443 (AR) prescribed product tolerance limit. Thus, concept, construction, materials, dimensions, and toleran

40、ces used in the design of test equipment shall be so selected and controlled as to insure that the test equipment will reliably indicate acceptability of a pro- duct which does not exceed 90% of the prescribed tolerance limit, and permit positive rejection when non-conforming. Construction shall be

41、such as to facilitate routine calibration of test equ ipmen t . 4.6 Test Methods and Procedures. 4.6.1 Storage Temperature. The Telescope shall be exposed to the temperatures specified in 3.3.1, utilizing testing equip- ment conforming with the “Test Facilities“ requirements of MIL- STD-810. In the

42、performance of this test, the temperatures shall be changed gradually to avoid thermal shock. After temperature stabilization at -800 and 71600F, the Telescope shall be exposed to each specified temperature for a minimum of 5 hours. Subsequent to being exposed to the above conditions, and upon retur

43、n to the standard ambient temperature of 4-600 and +9OOF, the Telescope shall be subjected to a visual and tactile examina- tion to assure that there is no evidence of mechanical and optical failure, cement separation, or deterioration. The unit shall then be tested in accordance with 4.6.2 through

44、4.6.9 to determine compliance with 3.3.2. 4.6,2 Vibration. The Telescope shall be subjected to the vibration test utilizing standard vibrating equipment capable of meeting the conditions of 3.3.2. The accuracy of the applicable test equipment and test equipment measurement shall be in accord- ance w

45、ith “Test Facilities“ requirements of MIL-STD-810. The Telescope shall be mounted in its normal operating position on the vibrating table by means of an adapter. The Telescope shall be vibrated in a vertical plane with the motion and frequency applied for the time period specified. At the conclusion

46、 of this vibration, the Telescope shall be subjected to a visual and tactile examination for damage such as bent or broken parts, glass chips, fractures, foreign matter, and cement separation; and to a functional examination of moving parts for undue irreg- ularities of movement, friction, or loosen

47、ess. Any one of the aforementioned defects shall be cause to consider a Telescope defective unless separa te defects-per-hundred type sampling plans are established or approved by the Government as part o the suppliers inspection system. Telescopes that have passed the above examinations shall he su

The optical surfaces of the Telescope shall be inspected for cleanliness in accorda

49、nce with MIL-0-13830. The Telescope reticle shall not contain particles of dirt in excess of the amount specified in 3.4.1. Area inspection of dirt particles shall be accomplished by means of a Scratch and Dig Standard conforming to Drawing C7641866 for a comparison of the area of the dirt particles with the dig size of the standard. The Telescope shall conform to its respective cleanliness requirement. This test shall be performe
