What Is ASTM E1559 Spacecraft Material Outgassing Contamination?
ASTM E1559 is a test method for identifying the outgassing kinetics of spacecraft materials, quantifying the amount of gas they release under vacuum, and assessing their impact on the surface. These characteristics play a crucial role in preventing issues such as optical degradation on a satellite by using a vacuum chamber, quartz crystal microbalances, and effusion cells.
It defines a test apparatus with associated procedures for measuring mass flux and its deposition onto the surface at various temperatures. The measurement is in SI units.

ASTM E1559 Spacecraft Material Outgassing Contamination FAQs
ASTM E1559 is a standard test method used to evaluate contamination and outgassing characteristics of spacecraft materials, assessing volatile emissions that may condense on sensitive surfaces.
ASTM E1559 is important because outgassing can contaminate optical instruments and surfaces, affecting mission performance, so materials must be evaluated to ensure cleanliness and reliability in space environments.
ASTM E1559 involves heating materials in a vacuum chamber and measuring released volatile compounds that condense on cooled collectors, simulating space conditions and contamination risks.
ASTM E1559 requires a vacuum chamber, temperature-controlled heating system, cold collectors, and analytical instruments to measure and quantify outgassed materials precisely.
Results are reported as collected volatile condensable material and outgassing rates, helping determine suitability of materials for spacecraft use and minimizing contamination risks in sensitive environments.
