28、l be implemented in accordance with “Suggested Guidelines for Accessible Lavatories in Twin Aisle Aircraft”. The handhold system in this lavatory shall meet the criteria in “Suggested Guidelines for Accessible Lavatories in Twin Aisle Aircraft” and 3.1.4 to accommodate both the typical passenger and
29、 the extra care/disabled passenger. 3.1.6 Lavatories shall be designed for ease of use, especially by passengers unfamiliar with the lavatory. Placards shall be used for clarity of necessary information. Symbolic placards are recommended and when used shall be implemented in accordance with AC 25-17
30、. 3.1.7 In addition to the “No Smoking in Lavatory” placards required by 14 CFR 25.791(d), a placard on the inside of the lavatory shall advise occupants that smoking is not allowed because of its potential fire danger. This placard should be rendered in accordance with ARP4740. 3.1.8 Illumination l
31、evels within the lavatory shall, at minimum, meet the values provided in AIR512.SAE INTERNATIONAL ARP1315E Page 5 of 6 3.1.9 The ashtray required by 14 CFR 25.853(g) shall be constructed of fire resistant (14 CFR 1.1) materials and have a lid to enclose smoking materials. 3.1.10 To meet the fire con
32、tainment requirements of 14 CFR 25.853, waste receptacles shall be tested per AC 25-17. The waste receptacle flap shall be clearly identified, readily distinguishable from an ashtray, self-closing, and not have finger “through holes”. The “No Cigarette Disposal” marking required by 14 CFR 25.791(c)
33、should be engraved (or equivalent) on the waste flap itself. Bonded placards shall not be used.

Easily opened
34、 and closed doors with straightforward access and an easily removable waste container shall be provided. It shall be impossible to install the removable container improperly. Compartment door latching shall be positive and indicate the latch engaged position. 3.1.12 Electrical wire, plumbing lines,
35、and other systems shall not be routed within the waste receptacle area of the waste compartment. It is acceptable to route these systems behind the waste receptacle in the back of the waste compartment, provided the waste receptacle area is separated from the systems with a compartment panel or equi
36、valent fire resistant shrouding. Removal of access panels shall not be required for cleaning waste receptacles.3.1.13 Smoke detectors and automatic (e.g., heat activated) fire extinguishing systems required by 14 CFR 25.854 shall be hidden or protected from occupants to reduce the risk of tampering
37、and shall be easily accessible to maintenance personnel for repair. The smoke detector system shall be implemented in accordance with ARP4001.

38、e sealed to provide a barrier preventing liquids from dripping or seeping into compartments or equipment below. 3.1.16 The toilet seat/shroud design shall not create a pressure seal between the seated passenger and the toilet. 3.1.17 A service panel shall be installed inside the lavatory and include
39、 an attendant call button and “Return to Seat“ sign. The “Return to Seat” sign should be symbolic not text with graphics per AC25-17. A passenger call from the lavatory shall also illuminate a light outside the lavatory and (optionally) on the attendant panel to indicate the lavatory from which the
40、passenger call originated. 3.1.18 Lavatory entry doors shall be designed to remain closed during emergency egress conditions and pressure loads caused by a rapid decompression (14 CFR 25.365(e)(g). 3.1.19 In addition to the requirements of 14 CFR 25.820, lavatory entry doors and door locks that oper
41、ate with rotating handles or knobs shall unlatch/unlock when turned in either direction. Operating the door lock shall provide a vacant and occupied indication outside the lavatory, as appropriate.3.1.20 The design of doors that open toward each other shall preclude jamming and interference that cou
42、ld lock the doors in a semi-open position. 3.1.21 Magnesium and magnesium alloys shall not be used. Chemical/substance usage shall be in accordance with local regulations such as RoHS and REACH. 3.1.22 A shroud for the toilet bowl and tank (if applicable) shall be designed to limit access for toilet
43、 system repair to maintenance personnel. 3.1.23 For security considerations, the toilet shall be designed to prevent the passage of solid objects greater than 2.0 inches (5.1 cm) in diameter (14 CFR 25.795).

44、 protected to prevent leakage and condensation from dripping on electrical wiring and equipment. 3.2.2 Plumbing shall be protected from freezing during “gate to gate” flight operations. Plumbing lines shall withstand freezing without damage or be able to be drained during a cold-soak condition, e.g.
45、, an airplane parked overnight in a cold climate. 3.2.3 Water faucet controls shall indicate hot and cold water. Faucet color coding of red to indicate “hot” and blue to indicate “cold” is suggested. Water faucets should be designed to turn off automatically in a time frame commensurate with good co
46、nservation practices. 3.3 Ventilation 3.3.1 Lavatories shall be ventilated. Minimum exhaust flow rates should be per Table 6-4 (private toilets) of ANSI/ASHRAE Standard 62.1 for odor control and the flow rate shall be high enough to prevent smoke from a lavatory fire from penetrating into the main p
