ECSS-Q-70-05A: Detection of organic contamination of surfaces by infrared spectroscopy (31 August 2005)

This Standard has been cancelled and replaced by ECSS-Q-ST-70-05C (6 March 2009).


This Standard defines the test procedures for detecting organic contamination on surfaces using direct and indirect methods with the aid of infrared spectroscopy. The following test methods are described:

  • Direct sampling of contaminants.
  • Indirect sampling of contaminants by washing and wiping.

This Standard also provides further guidance on interpreting the spectral data obtained through:

  • Qualitative interpretation of the spectral results.
  • Quantitative interpretation of the spectral results.

The test methods described in this Standard apply to controlling and detecting organic contamination on all manned and unmanned spacecraft, launchers, payloads, experiments, terrestrial vacuum test facilities, and cleanrooms.
