DIN EN 16603-35-06 PDF Download

For spacecraft propulsion components, the DIN EN 16603-35-06 standard, which is comparable to ECSS-E-ST-35-06, concentrates on the cleanliness criteria. Its main objective is to make sure that the propulsion systems, subsystems, and parts are made in a way that makes cleaning simple and discourages the buildup of pollutants.

The standard outlines the essential cleaning techniques as well as the cleanliness standards, including allowable particle, impurity, and moisture levels. It also specifies the standards for judging the degree of cleanliness and the circumstances under which cleaning or cleanliness verification should occur.

The propulsion systems covered by this standard include those that utilize hydrazine, monomethyl hydrazine, or MON, nitrogen, helium, propane, butane, and xenon. It acts as the cornerstone of the European spacecraft and spacecraft propulsion industries, directing them toward reaching and upholding the necessary levels of propulsion system cleanliness.

Although the primary focus of this standard is spacecraft propulsion, it is also applicable to satellite programs, manned spacecraft, and the ground support machinery they require. The ECSS-Q-ST-70-01 standard addresses the standards for external cleanliness, including those related to fungi and outgassing. In accordance with the ECSS-S-ST-00 standard, the DIN EN 16603-35-06 standard can also be modified to fit the unique requirements and limitations of certain space projects.
