AS1501D
This document covers flexible and semiflexible, reinforced and unreinforced air hoses fabricated from laminated and impregnated fabric, intended for use in aircraft heating, air conditioning, ventilating, defrosting, and/or deicing systems.
Rationale:
Add new form 3 that applies to grade E. Add new grade “E” that allows negative internal pressure and increases diameter to 12 inches to expand the usage of AS1505 in the industry. Replace MS33660 (obsolete) with AS5131 (equal replacement).
