30、ing film from the supporting medium or other detrimental effects on the serviceability of the mirror. 4.6.3 Humidity. The mirror shall be subjected to the humidity test of MIL-STD 810, Method 507. The clarity of the image shall not be affected and the specular reflectivity shall not be reduced when

31、tested in accordance with paragraphs 4.6.8 and 4.6.9. 4.6.4 Salt fog. The mirror shall be subjected to the salt fog test of MIL-STD-810, Method 509 except the spray shall be for a continuous 50 hours.

35、 with the plunger near the center of the mirror. b. By three fixed legs that need not be equispread. c. With an accurately formed template. d. With any other means acceptable to the inspector. 4.6.8 Image. Clarity of image shall be determined by viewing with the naked eye the reflection of an object

36、 in the mirror. Examination for noticeable distortion of the image shall be made as the mirror is rotated 45 degrees both to the right and left of the line of sight. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-5755E 6 4.6.9 Reflectivity.

37、The specular reflectivity shall be determined by directing a substantially collimated beam of incandescent light at approximately 45 degrees onto the mirror and directing the fraction of this beam specularly reflected into a receptor that shall have a spectral sensitivity approximating the luminosit

38、y function of the standard observer of the International Commission on Illumination. The fraction of the beam specularly reflected shall be determined either by actual measurement of the incident and reflected beams or by comparison of the beams reflected by the test mirror and with that from a suit

39、able calibrated standard mirror. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor personnel, these personnel need to contact the respo

Packaging requirements are maintained by the inventory control points packaging activities within the military service or defense agency, or within the military services system command. Packaging data retrieval is available from the mana

41、ging military departments or defense agencys automated packaging files, CD-ROM products, or by contacting the responsible packaging activity. 6.
