ASTM E2311 – Standard Practice for QCM Measurement of Spacecraft Molecular Contamination in Space

1.1”This practice provides guidance for making decisions concerning the use of a quartz crystal microbalance (QCM) and a thermoelectrically cooled quartz crystal microbalance (TQCM) in space where contamination problems on spacecraft are likely to exist. Careful adherence to this document should ensure adequate measurement of condensation of molecular constituents that are commonly termed ”’contamination”’ on spacecraft surfaces.
