23、ply additional remover conforming to the control formulation of TT-R-2918, type I, to cover any remaining coating and allow it to dwell for an additional 4 hours. Immediately after this second 4 hour exposure, the test panels shall be scraped with a rubber scraper to remove the bulk of the loosened
24、coatings and remover residue. The test panels shall then be rinsed with cool tap water and brushed with a soft, nylon bristle brush. Paint removal shall be determined for each test panel by estimating Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-M
25、IL-PRF-22750G 19 the percentage of the substrate revealed by the stripping process. The result shall be the average of the two panels tested. The result shall conform to 3.5.19. Method B: Two test panels, prepared as specified in 4.7.18 and weathered for no less than 500 hours as directed in 4.6.9 s
26、hall be placed on a rack at a 60 angle with the horizontal. Enough paint remover, conforming to the paint stripping efficiency requirements of MIL-R-81294 type I or II, shall be poured along the upper edge of each test panel to completely cover the coating surface. After no less than 60 minutes of e
27、xposure, the loosened coating shall be brushed off, and the test panels shall be rinsed while brushing under a stream of cool water. The result shall be the average of the two panels tested. The result shall conform to 3.5.19. 4.7.28 Toxic ingredients. Other than PCBTF, the manufacturer shall certif
28、y that the primer contains no benzene (benzol), chlorinated solvents or ethylene based glycol ethers and their acetates. Nonconformance to 3.5.20 constitutes failure of this requirement. 5. PACKAGING 5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the con
29、tract 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 responsible packaging activity to ascertain packaging requirements. Packaging requirements are maintained by the Inventory Control Points packaging act
30、ivities within the Military Service or Defense Agency, or within the military services system command.

With respect to products requiring qualification, awards will be made only for products which are, at the time of award of contract, qualified for inclusion in the QPD, whether or not su
37、ch products have actually been so listed by that date. The attention of contractors is called to this requirement and manufacturers are urged to arrange to have the products that they propose to offer to the Federal Government tested for qualification in order that they may be eligible to be awarded
38、 contracts or purchase orders for the products covered by this specification. Samples for QPD testing (see 4.2) should be submitted to ARL, ATTN: RDRL-WMM-C, Organic Coatings Team, Building 4600, Deer Creek Loop, APG, MD 21005-5066. 6.4.1 Extension of qualification for color. For type I, once qualif
39、ied for color numbers 17925 and 36375, qualification will extend to other gloss, semi-gloss and lusterless colors, with the exception of color number 34095. Color number 34095 must be qualified separately. For type II, qualification for color number 24533 along with color chips and statements of com
40、position for 17925 and 36375 will extend to other gloss, semi-gloss and lusterless colors. Color 34095 requires separate qualification. For type III, qualification for color number 24533 along with color chips and statement of composition for 36375 will extend to other semi-gloss and lusterless colo
41、rs. 6.4.2 Conformity to qualified sample.
