This standard establishes the minimum requirements for materials, processes, and engineering practices for the design of pneumatic ground systems for use at KSC. Where the requirements of this standard do not meet the minimum program or project requirements, the latter shall take precedence.This standard applies to all equipment, whether installed in facilities or portable, which handles gaseous media, including but not limited to breathing air, helium, hydrogen, methane, nitrogen, oxygen, and mixtures of these gases.This standard does not apply to facility compressed air systems operating at or below 150 psig, vacuum systems, portable or mobile equipment covered by Department of Transportation (DOT) 49 CFR regulations, or life support equipment regulated by National Institute for Occupational Safety and Health (NIOSH), Occupational Safety and Health Administration (OSHA), or KSC-STD-Z-0008.Design requirements for vacuum and compressed air systems operating at or below 150 psig can be found in KSC-DE-512-SM.These requirements apply to new equipment that has not been verified to meet requirements of a previous revision of this standard. Equipment designed or fabricated prior to the effective date of this standard may be verified as acceptable for use against the requirements of a previous revision of this standard. Any design changes to such equipment shall meet the requirements of this revision of this standard.Public Access
