Space product assurance - Material selection for controlling stress-corrosion cracking; English version EN 16602-70-36:2014
Raumfahrtproduktsicherung - Kriterien für die Werkstoffwahl zur Vermeidung von Spannungsrisskorrosion; Englische Fassung EN 16602-70-36:2014
Overview
This standard covers the following processes of the general materials, mechanicals parts and processes (MMPP) flow of ECSS-Q-ST-70: The selection of metal alloys for which preference is given to approved data sources (Table 5-1 to Table 5-3). The criticality analysis to determine if a stress corrosion cracking (SCC) evaluation is necessary. This standard sets forth the criteria to be used in the selection of materials for spacecraft and associated equipment and facilities so that failure resulting from stress-corrosion is prevented. It is intended to provide general criteria to be used in stress-corrosion cracking control, which begins during design thanks to a methodological material selection. This document does not intend to include all factors and criteria necessary for the total control of stress corrosion cracking in all alloys. The criteria established in this standard are only applicable to designs for service involving exposure conditions similar to testing conditions As regards weldments, this standard is applicable to aluminium alloys, selected stainless steels in the 300 series and alloys listed in Table 5-1. This standard is not applicable to listed materials whose behaviour differs at elevated temperature and in specific chemical. This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00. This document (DIN EN 16602-70-36:2014) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN (Germany). This document supersedes DIN EN 14101:2002-10. This document has been developed to cover specifically space systems and has therefore precedence over any EN covering the same scope but with a wider domain of applicability (for example: aerospace). The responsible German body involved in its preparation is Working Committee NA 131-10-01 AA "Interoperabilität von Informations-, Kommunikations- und Navigationssystemen" ("Interoperability of information, communication and navigation systems") at the DIN Standards Committee Aerospace (NL).
