The individual item requirements shall be as specified herein and in accordance with the applicable specification sheet. In the event of any conflic
23、t between the requirements of this specification and the specification sheet, the latter shall govern. NOTE: All requirements pertain to Class 1, Class 1a, Class 2, Class 2a, Class 3 and Class 3a MCEP systems unless otherwise specified. 3.2 Qualification. Eyewear furnished under this specification s
24、hall be products that are authorized by the qualifying activity for listing on the applicable qualified products list before contract award (see 4.1.1 and 6.3). A process in advance of and independent of an acquisition by which a manufacturers capabilities, or a manufacturers or distributors product
25、s are examined, tested, and approved to be in conformance with specification requirements, and subsequent approval for or listing of products on a qualified products list (QPL) or manufacturers on a qualified manufacturers list (QML) (see 4.1.1.2 and 6.3). 3.3 First article.

Recycled, recovered, or environmentally preferable materials should be used to the maximum extent possible, provided that the material meets
27、 or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs. 3.5 System configuration. 3.5.1 General. The MCEP system shall consist of a system containing: eyewear (Class 1 spectacles, Class 1a spectacles with capability to be compatible with the
28、 UPLC, Class 2 goggles, Class 2a goggles with capability to be compatible with the UPLC, Class 3 hybrid goggle, or Class 3a goggles with capability to be compatible with the UPLC), spare lens (with nosepiece, if applicable) and carrying case, instruction booklet, cleaning Provided by IHSNot for Resa
29、leNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-32432(GL) 5 cloth, anti-fog reapplication and a retaining strap. Lenses shall be capable of being easily removed from the primary frame and replaced with another lens. For those products designed without a frame around th
30、e lens, the lens shall be easily removed from the supporting structure (i.e., temple arms and/or retention strap) and replaced with another lens. Goggles shall also include a protective sleeve. Classes 1a, 2a and 3a shall include any adaptors required to interface with the UPLC system. a. Class 1 sp
31、ectacles. Class 1 spectacles are defined as eyewear that protects the wearers eyes from hazards/threats associated with fragmentation and light energy; additional wind/dust protection in the form of a seal around the eye socket or spectacle/frame perimeter is optional. If a removable wind/dust prote
32、ctive seal is proposed as part of the configuration, it shall be included as part of the kit, and the kit shall meet all specification requirements both with and without the removable seal in place. Primary means of retention for spectacles shall be temple arms or retention strap (for those designs
33、that do not have temple arms); an additional retention strap shall be included with the system for use in conjunction with, or in place of, the temple arms for designs that include temple arms. b. Class 1a spectacles. Class 1a spectacles are defined as eyewear that protects the wearers eyes from haz
34、ards/threats associated with fragmentation and light energy and is compatible with the UPLC. Additional wind/dust protection in the form of a seal around the eye socket is optional. Primary means of retention for spectacles shall be temple arms or retention strap (for those designs that do not have
35、temple arms); an additional retention strap shall be included with the system for use in conjunction with, or in place of, the temple arms for designs that include temple arms. c. Class 2 goggles. Class 2 goggles are defined as eyewear that protects the wearers eyes from hazards/threats associated w
36、ith fragmentation and light energy, as well as from wind and dust, providing a protective seal around the eyes. The primary means of retention for goggles shall be a goggle strap. A protective sleeve shall be provided for the goggle when not in use (such as when stowed on helmet). If a removable fac
37、efoam is proposed as part of the configuration, it shall be included as part of the kit; the kit shall meet all specification requirements both with and without the removable facefoam. d. Class 2a goggles. Class 2a goggles are defined as eyewear that protects the wearers eyes from hazards/threats as
38、sociated with fragmentation and light energy, as well as from wind and dust, providing a protective seal around the eyes and is compatible with the UPLC. The primary means of retention for goggles shall be a goggle strap. A protective sleeve shall be provided for the goggle when not in use (such as
39、when stowed on helmet). e. Class 3 hybrid goggles. Class 3 hybrid goggles are defined as eyewear that provides the same protection as the goggle, with the exception that it cannot take a 3rd(center) impact during ballistic fragmentation testing due to the physical nature of the design (i.e., either
40、a goggle design with individual right and left lenses or a goggle design Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-PRF-32432(GL) 6 with a lens height of less than five times the diameter of the projectile (2.73 cm) for the center section of
41、 the lens). f. Class 3a hybrid goggles. Class 3a hybrid goggles are defined as eyewear that provides the same protection as the goggle, with the exception that it cannot take a 3rd(center) impact during ballistic fragmentation testing due to the physical nature of the design (i.e., either a goggle d
42、esign with individual right and left lenses or a goggle design with a lens height of less than five times the diameter of the projectile (2.73 cm) for the center section of the lens) and is compatible with the UPLC. Note: It is possible that some eyewear may be capable of being configured as, and qu
43、alified as, more than one Class of MCEP system provided all requirements for each respective Class of MCEP system are met. 3.5.1.1 Eyewear. Eyewear shall provide protection to the eye against ballistic (fragmentation) threats, as well as from electromagnetic radiation, to include bright sunlight and
44、 harmful ultraviolet (UV) radiation. Ballistic fragmentation protection and UV protection is required in all possible configurations. At least one configuration shall protect the eye from bright sunlight (i.e., sunglasses). Class 1a, 2a and 3a shall have a means of holding the UPLC. NOTE: Here, a le
45、ns is defined as an optical quality protective shield for the eye(s). Configuration is defined as a lens, or combination of lenses, arranged together to achieve the desired protection and prescription. No more than two (2) types of lenses (or four exposed surfaces), including prescription lenses, sh
46、all be arranged in front of the eyes in any configuration. A self-contained lens system (i.e., a thermal lens with a sealed space between two lenses, an electrochromic lens configuration, etc.) shall be counted as two surfaces (front and back). Those surfaces that are physically sealed in between sh
47、all not be counted. 3.5.1.1.1 Color. Class 1 and Class 1a frames shall be available in Black 357. Class 2, Class 2a, Class 3 and Class 3a frames shall be available in Black 357, Tan 499 and Foliage Green 504. The finished eyewear shall match the standard sample for shade and appearance, and shall, u
48、nless otherwise indicated, be equal to or better than the standard sample with respect to all characteristics for which the sample is referenced (see FED-STD-595C). Retention straps and protective sleeves shall match the eyewear frame in solid color and/or corresponding US military camouflage patter
49、n, and shall match the corresponding standard for shade and appearance. Carrying cases shall match the eyewear frame in solid color and/or corresponding US military camouflage pattern . Findings (thread, zippers, webbing, snaphooks, etc.) shall be a reasonable match to the carrying case. Matte finishes are preferred. (see 6.2). 3.5.1.2 Carrying case. A carrying case shall
