ISO 11227:2012
Space systems -- Test procedure to evaluate spacecraft material ejecta upon hypervelocity impact
Product Details
ISO 11227:2012 establishes the requirements to be satisfied for the test methods in order to characterize the amount of ejecta produced when a surface material is impacted by a hypervelocity projectile. Its purpose is to evaluate the ratio of ejecta total mass to projectile mass, and the size distribution of the fragments. These are the necessary inputs for modelling the amount of impact ejecta that a surface material might release during its orbital lifetime, thereby helping to assess its suitability for space use while mitigating the production of small space debris.
The purpose of ISO 11227:2012 is to provide data that need to be taken into account in the selection of outer spacecraft materials, though the selection is not based on these criteria alone.
The experimental procedure defines
- the type of facility to be used,
- the size, velocity and type of projectile to be used,
- the evaluation of impact ejecta released,
- the reporting of test results, and
- the quality requirements to be used.
ISO 11227:2012 is applicable to spacecraft and launch vehicles operating in all types of Earth orbits.
