DIN EN 16602-70-55:2015-12

This standard defines test procedures for quantitative and/or qualitative microbiological examination of surfaces of flight hardware and in microbiologically controlled environments (for example, cleanroom surfaces, cleanroom air, isolator systems). The following test methods are described: surface and air sampling and detection of biological contaminants with swabs, wipes, contact plates and air samplers, followed by cultivation for bioburden determination; sampling of biological contaminants by DNA analysis from swabs and wipes. The test methods described in this standard apply to controlling the microbiological contamination on all manned and unmanned spacecraft, launchers, payloads, experiments, ground support equipment, and cleanrooms with planetary protection constraints. This standard does not address molecular contamination control. This standard does not address the principles and basic methodology for controlling cleanrooms and associated controlled environments with constraints on particulate contamination. 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 16602-70-55:2015) has been prepared by Technical Committee CEN/CLC/TC 5 "Space", the secretariat of which is held by DIN (Germany). This document has been prepared specifically to deal with space systems and therefore takes precedence over any European Standard, as it has the same scope but a wider scope (for example aerospace). The responsible German standardization committee is Working Committee NA 131-06-02 AA "Interoperabilität von Informations-, Kommunikations- und Navigationssystemen" ("Interoperability of information, communication and navigation systems") at DIN Standards Committee Aerospace (NL).
