Revision Plan of ISO11227 Considering Oblique Impact Tests

The number of space debris is continuously increasing, and the risk of collision with a spacecraft is also increasing Secondary debris called ejecta is specifically threat to spacecraft, so an international standardization of the test procedure to evaluate ejecta, was developed and published as ISO11227 on September 15, 2012. This paper intends to show the necessity of oblique impact test by comparing spacecraft material oblique impact with normal impact and to consider the experimental condition of oblique impact test to revise this standard.
