BS ISO 27875:2019 pdf free.Space systems – Re-entry risk management for unmanned spacecraft and launch vehicle orbital stages
Re-entry risk management shall be conducted according to ISO 17666, which is briefly explained in Annex B. This document mainly focuses on the estimation of the risk of casualty and partly on ground pollution. This document also presents requirements for when controlled re-entry would be conducted to reduce risk. This document acts as a part of a system safety programme based on ISO 14620-1.As required in ISO 14620-1, safety representatives shall be appointed. Safety representatives shall be responsible for safety activities, have the right to access related data, and be authorized to reject any project document, stop any project activities, or interrupt hazardous operations. As required in ISO 14620-1, at each design or operation phase, a review committee should review the result of the safety assessment, review the plan for the next phase, and endorse the decision to proceed to the following phase. If there are requirements that cannot be met, a request for deviation or waiver is generated and reviewed, and the space vehicle is disposed according to ISO 14620-1.
A Re-entry Risk Assessment and Mitigation Plan (RRAMP) shall be prepared and updated throughout the project life cycle as part of the safety data package specified in ISO 14620-1.
The RRAMP will define the work plan corresponding to each requirement in this document and detailed schedules for critical activities (design, analysis and testing reviews) throughout the life of the project.Typical contents of the RRAMP are given in Annex A. The scoring schemes for the severity of consequence of re-entry hazards are defined by the national authority. Based on ISO 17666, risk is assessed by the risk magnitude expressed as the combination of its severity and likelihood (see Annex B, and ISO 17666).
The scoring is typically related to the casualty area (see 5.5.1.2) in the case of casualty risk, damage of properties in the case of social risk, or pollution on the ground in the case of environmental risk (for example, see Table B.1, or ISO 17666). Generally, a risk index will be defined as a combination of severity and likelihood, and a risk magnitude will be defined for each risk index.BS ISO 27875 pdf free download.
