Title (German)

Raumfahrtproduktsicherung - Kompatibilitätstests für Material und Hardware in Sterilisationsprozessen; Englische Fassung EN 16602-70-53:2015

Overview

This Standard describes a test protocol to determine the compatibility of materials, components, parts, and assemblies with sterilization processes. It is dedicated to test on non-flight hardware only. Any additional requirements that can be imposed by the potential use of test samples as flight hardware are not covered in this document (for example, handling requirements). This Standard covers the following: - Identification of critical test parameters to establish functional integrity of the hardware; - Typical test protocols; - Acceptance criteria. Statements about compatibility of materials and components with sterilization processes in this document are made in general terms only. Other factors for determination of whether a material or component is suitable for a particular mission system application include: - The potential number of sterilization cycles to which the material/component will be subjected in their live cycle; - The additional stresses on materials/components introduced when they have become part of a larger unit/equipment/system undergoing sterilization; - Compatibility of sterilization processes at, for example, materials level. This compatibility does not automatically guarantee that it will perform to its requirements in an assembly. The final application and possible interactions at higher assembly level are important considerations for qualification; - Qualification of hardware achieved by specific sterilization parameters. They cannot be necessarily extrapolated to other sterilization parameters, not even within the same sterilization process; - The drift in performance that can be induced by sterilization processes. This drift can cause equipment to fail to meet their specified performance requirements, even though each individual element/component remains within spec. An example of this is where 'Select-on-test' components are used to operate a component over a critically narrow range its full performance. To assess ultimately the suitability/compatibility of a material or component for an application requires a full consideration of the impact of sterilization processes to which it is subjected during its whole life. This includes sterilization processes it undergoes from the time it is a standalone component/material right through to when it experiences final sterilization as part of the complete system. This standard may be tailored for the specific characteristic and constraints of a space project in conformance with ECSS-S-ST-00. This document (EN 16603-70-53:2015) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN (Germany). This document has been developed to specifically cover space systems and therefore has precedence over any European Standard since it covers the same scope but with a wider domain of applicability (for example aerospace). The responsible German body is Working Committee NA 131-10-01 AA "Interoperabilität von Informations-, Kommunikations- und Navigationssystemen" ("Interoperability of information, communication and navigation systems") of the Aerospace Standards Committee (NL) at DIN.
