Spacecraft Material Outgassing Measurements from Goddard Space Flight Center

NASA's Goddard Space Flight Center compiled outgassing data for spacecraft materials using equipment developed by Stanford Research Institute. The dataset supports the ASTM E 595 standard test method for Total Mass Loss and Collected Volatile Condensable Materials. It was used to select materials meeting criteria of under 1.0% TML and 0.10% CVCM.

Use Cases

• Analyze Total Mass Loss (TML) values to rank materials for low-outgassing spacecraft applications
• Model the relationship between Collected Volatile Condensable Material (CVCM) and material composition for flight selection
• Validate material performance against the ASTM E 595-77/84/90 standard using historical test data
• Compare outgassing properties from SRI and GSFC test apparatus results documented in referenced reports

Strengths

• Data underpins the established ASTM E 595 standard test method for material outgassing
• Compilation includes results from tests conducted at both Stanford Research Institute and Goddard Space Flight Center
• Materials are filtered to meet specific, documented performance thresholds (1.0% TML, 0.10% CVCM)
• Dataset is referenced across multiple technical reports (References 3-9) for material selection

Limitations

• Specific sample size, row count, and columnar structure are not provided in the input
• Core data collection period (1964-1967) may not reflect properties of modern composite materials
• Data accessibility and machine-readability are unclear as file formats and structure are unknown
