6、d was developed by the NASA George C. Marshall Space Flight Center (MSFC) and the NASA John C. Stennis Space Center (SSC) to provide uniform engineering and technical requirements across both Centers for contamination control of propellants and pressurants. This standard has been endorsed and approv
7、ed for use at the MSFC and the SSC. This standard establishes core requirements, practices, and methods to assure the quality of propellants and pressurants are maintained. The movement toward joint standardization is driven by past contamination experiences and different technical requirements and
8、practices at both Centers. Non-standard Center practices complicate test interfaces and increase operational risks and costs.

22、: MSFC-STD-3535 Baseline Effective Date: April 8, 2009 Page 7 of 42 CHECK THE MASTER LIST - VERIFY THAT THIS IS THE CORRECT VERSION BEFORE USE 1. PURPOSE The purpose of this standard is to specify the minimum requirements for the certification and maintenance of propellant and pressurant (P/P) syste
23、ms used for the purpose of rocket engine testing, test operations, ground support operations, center laboratory operations, and center facility operations. 2. APPLICABILITY This standard is applicable to ground-based rocket propulsion test, test support, center sample analysis laboratory, and center
24、 operation facilities for P/P requiring system certification. P/P quality provided to the user interface points shall meet or exceed program, test article, center or laboratory requirements. Programs or customers may impose additional requirements. In such cases, process changes and supplemental pro
25、cedures may be required. Propellants and pressurants covered in this standard are high purity air (HPA), gaseous nitrogen (GN2), liquid nitrogen (LN2), gaseous hydrogen (GH), liquid hydrogen (LH), gaseous oxygen (GOX), liquid oxygen (LOX), gaseous helium, and liquid helium, and breathing air. 3.
