ISO 14951-5:1999 PDF

Scope: This part of ISO 14951 specifies limits for the chemical composition and physical properties of N2O4 propellant and test methods for verification of propellant composition. This part of ISO 14951 is applicable to N2O4 propellant of the following types and grades, intended for use as an oxidizer in propellant systems of space systems: — types — NTO: nominal 99,5 % N2O4 purity with red-brown colour; — MON-1: nominal 99 % N2O4 and 1 % NO with green colour; — MON-3: nominal 97 % N2O4 and 3 % NO with green colour; — MON-10: nominal 90 % N2O4 and 10 % NO with green colour; — MON-25: nominal 75 % N2O4 and 25 % NO with green colour; — grades: — standard: no iron requirement; — low-iron: 0,5 μg/g iron maximum. This part of ISO 14951 is applicable to propellant used in both flight hardware and ground facilities, systems, and equipment. It is applicable to influents only to the extent specified herein. CAUTION — Nitrogen tetroxide, in the liquid or vapour form, is toxic and volatile. Care should be taken in the handling and storage of nitrogen tetroxide to prevent contact with the human body and with materials that are not compatible.
