BS EN 16602 is a standard that discusses space product assurance.
BS EN 16602-70-50 defines the requirements and guidelines for the measurement of particulate contamination on the surfaces of spacecraft systems and those of the cleanrooms or other cleanliness-controlled areas in which they reside.
BS EN 16602-70-50 includes the measurement of particulate contamination that is present on the spacecraft or cleanroom surfaces via the use of representative witness samples placed in the vicinity of the spacecraft hardware, the direct measurement of particulate contamination levels on surfaces of spacecraft hardware from the direct surface transfer to adhesive tape-lift samples and particulate contaminant levels within fluids used for the cleaning or rinsing of such spacecraft system components and cleanroom surfaces.
BS EN 16602-70-50 also defines the methods to be used for the visual inspection of spacecraft system hardware for particulate contamination.
Note 1: The measurement of airborne particulate contamination is not covered in BS EN 16602-70-50 and ISO 14644 “Cleanrooms and associated controlled environments” applies in this case.
Note 2: BS EN 16602-70-50 does not cover particulate contamination monitoring for spacecraft propulsion hardware.
BS EN 16602-70-50 on particles contamination monitoring for spacecraft systems is applicable for:
Particulate contaminants can be hazardous to spacecraft in several ways including failure of precision mechanisms, light absorption and scattering, points of high local electric field and associated electrostatic discharge, and noise on electrical contacts.
It is therefore important to control, measure and verify the particulate contamination levels on spacecraft systems and the environments in which they reside so that an assessment can be made on any hazards that may be present as a result of such contamination.
BS EN 16602-70-50 ensures that the particle monitoring of spacecraft systems and cleanrooms utilized in the production of such systems; is carried out appropriately and is controlled both in terms of the precision of the measurements and the reproducibility of such measurements.
Guidelines provided in BS EN 16602-70-50 assist you with the requirements to perform an inspection of particles for spacecraft systems.
BS EN 16602-70-50 provides requirements on quantitative and visual inspection methods.
Thus, BS EN 16602-70-50 assists quality compliance personnel in inspecting contamination items and preparing reports to achieve quality assurance.
