The cleaning
31、, pretreatment and gray enamel shall produce a uniform, continuous, tightly-adhering coating reasonably free on all surfaces from cracks, scratches, holidays and other film defects or irregularities that may adversely affect the corrosion-resisting properties of the coating. Either type I, class 1 o
32、r class 2 of MIL-E-15090, or class 1 and class 2 of MIL-E-19603 may be used. As an optional method, body, end rings and covers may be roller coated with a primer conforming to MIL-P-19602 followed with a gray enamel coating conforming to MIL-E-19603, (color modified to match the color specified in M
33、IL-E-15090) and a varnish coat conforming to MIL-V-21064.3.6.3 Recovered materials: Unless otherwise specified herein, all equipment, material and articles incorporated in the products covered by this specification shall be new and shall be fabricated using materials produced from recovered material
34、s to the maximum extend practicable without jeopardizing the intended use. The term “recovered materials“ means materials which have been collected or recovered from solid waste and reprocessed to become a source of raw materials, as opposed to virgin raw materials. None of the above shall be interp
35、reted to mean that the use of used or rebuilt products is allowed under this specification unless otherwise specifically specified.SAE AS210041 - 6 -3.7 Marking:Canisters shall be marked on the side with the following information:Carbon dioxide (CO2) absorbent (lithium hydroxide)Do not open until re
