Title Measurements of hypergolic fuels' and oxidants' permeation through commercial protective materials. Part II, Nitrogen tetroxide, monomethylhydrazine, and anhydrous hydrazine
Bibliographic information Jan.1991, Vol.52, No.1, p.20-29. Illus. 26 ref.
Abstract Forty materials were tested to determine their relative resistance to permeation by nitrogen dioxide (NO2), monomethylhydrazine (MMH), and hydrazine (Hz) after exposure to the liquid hypergolic propellants dinitrogen tetroxide (N2O4), MMH, and anhydrous hydrazine (AHz), respectively. A new piece of material was used in each test. The materials were not preconditioned, nor was exposure to the hypergolic propellants repeated. In these tests, the materials were clamped in a static test cell that permitted one side of the fabric to be exposed to the oxidant or fuels, while the other side of the fabric was monitored for NO2, MMH or Hz concentrations with an electrochemical analyser. The materials tested were candidates for use in protective suits, gloves, boots, and hood windows during USA Air Force or National Aeronautics and Space Administration (NASA) propellant loading operations. The most promising materials will be tested further by standard American Society for Testing and Materials (ASTM) methods.
