Which standards apply to spacesuits? • There is a “spacesuits” section (Section 11), but the entire document applies to spacesuits “unless otherwise specified” 4

Which standards apply to spacesuits? • However, many standards are clearly not applicable to spacesuits… e. g. … while others might or might not be intended to apply… e. g. … and others could potentially apply depending on the design approach e. g. 5

Which standards apply to spacesuits? • Some standards might apply to LEA suits but not EVA suits or vice-versa e. g. • NASA-STD-3001 makes no distinction between EVA and LEA spacesuits • In some cases, there is redundancy / duplication between Section 11 and the preceding sections • Additionally, some stakeholders disagree with the content of standards that are applicable or potentially applicable to spacesuits – e. g. In-suit nutrition, hydration, relative humidity, pressure changes 6

Approach • Define LEA and EVA spacesuit systems • Create an Applicability Matrix for all sections and all standards of 3001 Vol 2 for LEA and EVA spacesuit systems: x 492 standards l a n otio N • Designate each standard as Applicable or Not Applicable to EVA and LEA spacesuit systems

Applicable vs. Non-Applicable 8

Human Integration Design Handbook • A “compendium of human spaceflight history and knowledge” • Includes an EVA Section (but no LEA) https: //ston. jsc. nasa. gov/collections/ trs/_techrep/SP-2010 -3407. pdf 9
