1. INTRODUCTION 

1.1 Scope of the Document 

This document defines the Product Assurance requirements applicable to Subcontractors to ASTRIUM for the 

EarthCARE programme. All products (equipment, software or services) procured in the frame of EarthCARE 

programme is required to conform to these Product Assurance requirements. 

These requirements are based on the ECSS series of documents or in ESA specific documents such as the 

PSS series when no equivalent ECSS is available. They amend the applicable documents when necessary to 

address some specific points. 

Subcontractors shall impose these requirements upon their lower tier subcontractors and suppliers as 

appropriate to the procured item. 

In this document, the term ASTRIUM means the Division or Business Unit project placing the contract. 

These requirements are applicable to: 

All delivered Hardware and Software models of the product 

Elements of the GSE which interface directly with flight hardware (e.g. connectors, cooling devices…) or which 

can have an impact on safety (e.g. EGSE, lifting devices) 

The requirements defined in this document are applicable to the EarthCARE project phases B, C/D and E1. 

If specific requirements are considered as non-applicable, impracticable or inefficient for implementation, the 

Subcontractor may propose alternative procedures to achieve the same objectives. These procedures are 

subject to approval by ASTRIUM on a case-by-case basis.
