This standard defines the requirements for bulk protective sleeve to provide fire resistance for aircraft hose assemblies, which will enable these assemblies to meet the requirements of AS1055.
NOTE: Use of this sleeve does not eliminate the need to demonstrate that the sleeved assemblies will meet the applicable requirements of AS1055.
The following publications form a part of this document to the extent specified herein. The latest issue of SAE publications shall apply. The applicable issue of other publications shall be the issue in effect on the date of the purchase order.

Nothing in this document,however, supersedes applicable laws and regulations unless a specific exemption has been obtained.
All sleeves furnished under this standard shall comply with the requirements of AS1055 when installed on the appropriate aircraft hose assemblies.
When installed on the appropriate aerospace hose assembly, the cut ends of the sleeving shall be protected with material that is compatible with the cover in order to prevent wicking of fluid to the inside of sleeving (see 3.4).
Butyl Rubber Composite (Type 1): The coating of the fiberglass firesleeve shall be butyl rubber with minimum .03 in (0.8 mm) thickness, grey or black in color, with green or silver identification markings.
The cut ends of the fiberglass (sleeve) and the ID of the sleeve shall be protected with an appropriate sealant (such as RTV silicone coating) or sleeve. Internal coverage shall extend approximately .75 in (19.1 mm) or to a point that will be under the clamp. The purpose of this protection/sealing is to minimize the probability of wicking fluid(s) into the body of the sleeve during casual (nonsubmerged) exposures. This may be accomplished by dipping, wiping, brushing, or appropriate sleeve. Any cracks or voids which expose the (white) fiberglass shall be recoated as required.SAE AS 1072F pdf free download.
