25、eservative compounds shall be applied to any portion of the mask or its components. Each mask shall be fitted with a faceform (Drawing 5-22-57 or 5-22-58, as applicable to mask size) as shown on Drawing 5-1-296. of lens tissue paper, 5 by 7 inches, conforming to NNN-P-40, shall be placed between the
26、 mask lens and the faceform in such a manner to prevent physical con- tact between the lens and faceforni. After insertion of the faceform into the mask, the mask lens shall be covered with paper, white, newsprint, 32 lb base. The paper shall be placed over the outside surfaces o? the lens and shall
27、 be securely attached to the facepiece by taping to prevent movement, with three pieces of 1-1/2 inches long by 3/4 inches wide, pressure-sensitive adhesive tape. A larger size paper taped to the faceform is acceptable, The paper shall be taped to the mask facepiece, one on each side of the chin por
28、tion and one over the top portion of the facepiece. tact with the interior mbber surfaces of the faceblank. The head harness assembly shall be tucked into the cavity of the faceform. shall then be placed inside the carrier. inside the carrier in such a manner so that the strap hardware shall not com

The assembly shall then be inclosed in a water-vaporproof, heat seal- able bag conforming to MIL-B-117, type I, class E, style 1, except that the heat sealable surface of the barrier material shall be a
31、nonplasticized type (such as polyethylene), the exterior surface shall be a non-woven, spun bonded polyolefin, thickness 0.006 + 0.0006 inch. The bag shall have inside dimen- sions of i5 by 18-1/2 inches-(opening at the i5 inch dimension). The bag shall be closed by heat sealing in accordance with t
32、he barrier mterial or bag manu- facturers recommendations for dwell , temperature and pressure requirements. This assembly shall be in accordance with the performance requirements for method IA-8 of MIL-P-116. Prior to sealing the barrier bag, exhaust only the amount of air necessary so that the bag
33、 will conform to the exterior shape of the carrier assembly (mask inclosed) without exerting pressure on this assem- bly. CAUTION: Exhausting excessive amount of air will cause distortion of the rubber components of the mask. The packaged mask shall then be placed in a fiberboard box conforming to P
