6.2
				FLAMMABILITY. All materials used in the portable PBE and any
				stowage container/case (including insulation on electrical wires)
				in a typical installed arrangement must be self-extinguishing.

Materials
				must comply with CS 25.853(a), Appendix F, Part I (a)(1)(iv).

 


6.2.1
				Any exposed portions of the portable PBE and stowage
				container/case must withstand a radiant heat flux of 1.0 BTU/ft²
				per second for 60 seconds, and remain functional when exposed to
				it.

 


6.2.2
				Radiant heat flux source must be of sufficient size so the
				portable PBE, any stowage container/case, and exposed parts of
				the unit are exposed in a manner that creates the heat flux at
				all the surfaces, in a typical as installed arrangement.

 


6.2.3
				Portable PBE must protect the user’s head and neck from
				dripping 392 °F (200 °C) plastic materials and
				withstand an 1 832 °F (1 000 °C) flame for
				5 seconds without material penetration while operating.

 

6.2.3.1
				Protection from dripping plastic material may be tested by
				several methods. One is to ignite a polypropylene rod and allow
				the drops to impinge on the various external materials, seams,
				and transparency. Adjust the drop height so that the drop contact
				temperature is at least 392 °F (200 °C).

6.2.3.2
				The 5-second 1 832 °F (1 000 °C) test is
				meant to protect a crew member wearing the portable PBE from an
				unexpected flame lick. Two main concerns are failure of the unit
				that would injure the wearer, and leakage of the breathable
				atmosphere that could produce an explosion or hazard. The test
				rig must expose the unit, while operating, to a 1 832 °F
				(1 000 °C) flame envelope. One company has used German
				Teklu burners with a flow rate of about 21 liters per minute. The
				flow rate and distance of the burner to the surface of the PBE
				unit being tested shall be adjusted to obtain the required
				temperature. In most cases the flame plume developed will not
				expose the complete unit. A segment can be passed through the
				flame plume to obtain the 5-second exposure period and then the
				unit can be rotated to the next segment and passed through the
				flame plume, and so forth, until the complete unit has been
				tested. Making a visual (videotape) record of this test might be
				useful documentation, in addition to the measured parameters.

 


6.2.4
				Heat Release and Smoke Density. Exposed panels/surfaces totalling
				more than one square foot in surface area must meet the heat
				release and smoke density requirements of CS 25.853,
				Appendix F, Parts IV and V. Guidance on these test requirements
				can be found in the Aircraft Materials Fire Test Handbook,
				DOT/FAA/AR-00/42, at www.fire.tc.faa.gov/handbook.stm.

 


6.2.5
				Battery Qualification. If the equipment uses a lithium battery as
				a power source, battery must meet the applicable battery
				standards:

6.2.5.1
				ETSO-C142a, Non-Rechargeable Lithium Cells and Batteries (see
				RTCA, Inc. document RTCA/DO-227, Minimum Operational Performance
				Standards for Lithium Batteries, dated June 23, 1995), or most
				current revision.

 

6.2.5.2
				ETSO-C179a, Rechargeable Lithium Cells and Lithium Batteries (see
				UL 1642, Standard for Safety for Lithium Batteries, fourth
				edition, dated September 19, 2005).

				Environmental Qualification

 


6.3.1
				High-Temperature Exposure: The portable PBE shall be soaked for
