Space systems — Methods to decide thermal vacuum test cycles of recurring production according to precipitation efficiency and reliability

Systèmes spatiaux — Méthodes pour déterminer les cycles d'essais sous vide thermique de la production récurrente en fonction de l'efficacité et de la fiabilité des précipitations

Abstract / scope

This document provides technical methods to calculate the precipitation efficiency and liability of a flight model by measuring the screening effectiveness of thermal cycles. This document is applicable to the recurring production unit and other hardware assembly levels, as either an option to reduce or a method to tailor the baseline number of cycles for thermal vacuum and thermal cycle acceptance tests.
