27、AE INTERNATIONAL AS8031A 4 of 15_ 8. (Continued):h. If positive pressure is required within the device to meet TSO and/or protective requirements noted herein, the pressure should be recorded during the qualification testing of the protective breathing system. The minimum mean positive pressure requ
28、ired must then be specified and marked on each device where applicable. For example:1. Goggles _ (part number) with oronasal mask, fullface mask, or hood _ (part number) with regulators _, _, _ (part numbers) delivering a minimum mean positive pressure of _ inches H202. Goggles _ (part number) with
29、oronasal mask, fullface mask, or hood _, positive pressure is not required.3. Aircraft demand regulator not required _. Gas source _. Type _. Gas flow _. Positive pressure _. Duration _.8.1 Cleaning:Except for those systems that are disposable or not reusable, it shall be possible to clean and steri
30、lize the device without adverse effects on its operation and performance. The manufacturer shall provide adequate instructions with each unit.9. DETAIL REQUIREMENTS:9.1 Each protective device shall maintain ratio of contaminant within the device - to ambient contaminant concentration of no more than
31、 _X_ for the respiratory protective device and no more than _Y_ for the eye protective device both with or without eyeglasses specified in 9.3.1. When respiratory protection and eye protection are integrated into a single or common compartmented device, such as fullface mask or hoods, the mean conta
32、minant protection factor is defined as the concentration inside the device divided by the concentration in the environment. This ratio is considered applicable respiratory protection and shall not exceed _Z_. Contamination protection shall be determined by testing as described in Section 12. Equival
33、ent test procedures and equipment may be used providing a similar level of accuracy and reliability can be demonstrated. The respiratory protection portion of the device shall meet the requirements of AS8026 except for those areas in conflict with this document. In these areas, this document shall t
34、ake precedence.SAE INTERNATIONAL AS8031A 5 of 15_ 9.2 Sizing Criteria:Each protective device that is furnished an aircrew member for protection from a toxic atmosphere can fulfill its intended function only if the device properly fits the intended wearer.Because the professional flying population -
35、male and female - present a very wide range of facial types and sizes, the intended users must personally assure that a good fit can be achieved using the standard protective equipment that is provided by the aircraft operator. Aircraft operators should provide an adequate fit and protective level t
36、o the widest possible range of their aircrew member. Individually fitted or custom items should be furnished when an aircrew member cannot be fitted by the standard items regularly provided.Manufacturers are encouraged to provide protective apparatus of universal sizes wherever feasible. When multip
37、le sizes are required to fit the full range of anticipated users, the apparatus is to be clearly marked or identified as to its size or intended user type.9.3 Donning:The design objective is that the device shall be capable of being donned within 15 s.9.3.1 The device shall also be capable of being
38、donned over and thereafter allow the user to wear corrective eyeglasses of maximum dimensions: 4.08 cm x 15.24 cm (2 in x 6 in). The device shall not compromise the nominal position of the eyeglasses so as to cause unacceptable distortion nor cause undue discomfort. Subjects who wear eyeglasses shou
39、ld meet the requirements of 9.1 with the eyeglasses on (i.e., one needs to be concerned with leakage around the eyeglass side arms).9.3.2 The manufacturer shall establish a donning procedure.9.3.3 Minor post-donning adjustment shall be allowed for fit and comfort.9.3.4 Protective device suspension s
40、ystem design, including straps, buckles, knobs, and other adjusting mechanisms, should consider angular relationships, strap pull-tab size, and force requirements in relation to force capability of the user population. The device must not prevent or inhibit normal range of movement. 10. COMMUNICATIO
41、NS:10.1 For Flightdeck Crewmembers:The protective device shall include an integral microphone when necessary to allow the user to communicate (speak) through the aircrafts communication system. Said microphone shall meet requirements of TSO C58.SAE INTERNATIONAL AS8031A 6 of 15_ 11. VISION:11.1 Prot
42、ective breathing equipment must include provisions designed to protect the eyes from smoke and harmful gasses. When worn by each test subject used in showing compliance with 12.1 the equipment must:11.1.1 Not cause a displacement of the spectacle frame sufficient to reduce distance visual acuity in
43、the forward direction of subjects wearing bifocal lenses using normal head movements. Goggle evaluation must be done when worn with the mask that completes the smoke protection combination.11.1.2 Permit peripheral vision in the horizontal meridian 120 (60 on each side of the center point) and in the
44、 vertical meridian of at least 60 (40 above and 20 below center point) when evaluated by standard arc perimeter techniques. Results are to be based on mean scores for all subjects. Goggle evaluation must be done when worn with the mask that completes the smoke protection combination.Transparent area
45、s of protective breathing equipment shall be designed to prevent condensation on the inside surfaces or shall include a means for removing any moisture that may condense on surfaces essential to vision.11.1.3 Light transmission, refractive deviation, optical haze and distortion shall be tested in ac
46、cordance with, and meet Table 8. USA Standard Z87.1 requirements of FAA report FAA-AM-78-41.12. QUALITY ASSURANCE:12.1 Qualification Testing:The manufacturer shall perform, or cause to be performed, the tests covered by this standard for initial qualification of the protective breathing device syste
47、m. Any tests required by this standard that have been performed on similar units may be omitted, provided the manufacturer shows in the test report the analyses establishing similarity of design, and the results of said tests. Each component of the protective breathing system shall be representative of production
