KSC-SPEC-P-0018, PROPELLANTS, RECOVERED NITROGEN TETROXIDE SOLUTION, SPECIFICATION FOR (10 JUL 1995)

KSC-SPEC-P-0018, PROPELLANTS, RECOVERED NITROGEN TETROXIDE SOLUTION, SPECIFICATION FOR (10 JUL 1995)., This specification covers the requirement for nitrogen tetroxide solution, also known as oxidizer solution (OS), recovered from propellant systems. Nitrogen tetroxide (N2O4)solution is actually a blend of N2O4, nitric acid (HNO3), and water (H2). This specification provides a means of categorizing recovered propellants for either reclamation for alternate reuse or for reprocessing to original manufacturing purity.
