To clean, remove dust and dirt with a lint free soft cloth, soft pap
26、er tissues or cotton balls. Clean with a mild detergent and water and blow dry or dry by using the soft cloth or tissues. Deep scratches may reduce the protection. This may be checked by running a fingernail over the scratch. If the fingernail catches the scratch, the visor should not be worn. THIS
27、VISOR IS A CON ;OLLE0 ITEM AND SHOULD BE DISPOSED OF IN ACCORDANCE WITH NAVAI R Manual 13-1 -6.7 This visor shall be worn only during daylight hours. It does not transmit enough light to be worn during the low light levels of dawn, dusk or at night. This visor is not intended as a replacement for th
28、e neutral density visor subassembly. Do not use this visor with magnifying optics (binoc- ulars, telescopes, etc.). DO NOT USE FOR PROTECTION AGAINST LASERS OTHER THAN THE INTENDED SEVEN WAVELENGTHS! 3.7 Workmanship. All visors shall be constructed to produce an item free from all defects which wiul

The occurrence of defects shall not exceed the acceptance criteria established in Table III. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for _ insp-ction. Un
30、less otherwise specified in the contract or purchase order, the contractor is responsible for the Performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other faci
31、lities suitable for the performance of the inspection requirewents specified herein, unless Government reserves the right to perform this specification where such inspections ies and services conform to prescribed di sapproved by the Government.

All items shall meet all he inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requir
33、ements in the specification shall not relieve the contractor of the respot-sibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice t
