Space product assurance - Flammability testing for the screening of space materials

This European Standard specifies a multi­test procedure for the determination of the flammability char-acteristics of non­metallic materials under a set of closely controlled conditions. The test procedure cov-ers both individual materials and materials used in configuration. This standard describes a series of tests to provide data for aid in the evaluation of the suitability of materials for use in a space vehicle crew compartment. The data obtained are in respect to the ease of ignition and the flame propagation char-acteristics of materials.

Raumfahrtproduktsicherung - Brennverhaltenstest für die Auswahl von Raumfahrtmaterialien

Diese Europäische Norm legt Prüfverfahren zur Bestimmung des Brennverhaltens von nichtmetallischen Werkstoffen unter definierten Bedingungen fest. Diese Verfahren gelten sowohl für Werkstoffe, die allein, wie auch für solche, die im Verbund eingesetzt werden. Die Ergebnisse der Prüfungen sollen eine Beurteilung der Eignung von Werkstoffen für den Einsatz in Mannschaftsräumen von Raumfahrzeugen ermöglichen. Die Prüfergebnisse lassen Schlussfolgerungen hinsichtlich der Entflammbarkeit der Werkstoffe wie auch hinsichtlich der Flammenaus-breitungseigenschaften zu.

Assurance produit des projets spatiaux - Essai de flammabilité pour la sélection des matériaux d'un projet spatial

La présente Norme européenne spécifie une procédure à essais multiples permettant de déterminer les caractéristiques d'inflammabilité des matériaux non métalliques dans un ensemble de conditions strictement contrôlées. La procédure d'essai couvre à la fois les matériaux individuels et l'ensemble des matériaux utilisés en configuration. La présente norme décrit une série d'essais destinés à fournir des indications permettant d'évaluer l'aptitude des matériaux à être employés dans le poste d'équipage d'un véhicule spatial. Les données obtenues concernent la facilité d'inflammation des matériaux et leurs caractéristiques de propagation des flammes.

Foreword
This document EN 14090:2002 has been prepared by CMC.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by August 2002, and conflicting national standards shall
be withdrawn at the latest by August 2002.
1)
It is based on a previous version originally prepared by the ECSS product assurance working group,
reviewed by the ECSS Technical Panel and approved by the ECSS Steering Board. The European Co-
operation for Space Standardization (ECSS) is a cooperative effort of the European Space Agency, Na-
tional Space Agencies and European industry associations for the purpose of developing and maintain-
ing common standards.
This standard is one of the series of space standards intended to be applied together for the manage-
ment, engineering and product assurance in space projects and applications.
Requirements in this standard are defined in terms of what shall be accomplished, rather than in terms
of how to organize and perform the necessary work. This allows existing organizational structures and
methods to be applied where they are effective, and for the structures and methods to evolve as neces-
sary without rewriting the standards.
The formulation of this standard takes into account the existing ISO 9000 family of documents.
Annex A is informative.
This standard includes a Bibliography.
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the fol-
lowing countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Iceland, Irela
