Space product assurance - Measurement of the peel and pull-off strength of coatings and finishes using pressure-sensitive tapes
This European Standard details a test in which pressure-sensitive tapes are used to assess the suitability of, for example, coatings, paints, films and other thin materials, proposed for use on spacecraft and associated equipment.
The following materials and assemblies are covered by this test method:
- organic coating, e.g. varnishes, paints and plastic films;
- metallic finishes on, for example, printed circuit boards, second-surface mirrors, thermal radiators, plastic films;
- adhesive layers;
- composite thin films;
- small assemblies, e.g. solar cells having attached glass covers.
Raumfahrtproduktsicherung - Ermittlung der Schäl- und Abziehfestigkeit von Überzügen und Beschichtungen unter Anwendung von Haftbändern
Diese Europäische Norm legt ein Prüfverfahren fest, bei dem mit Haftbändern die Eignung von Überzügen, Anstrichen, dünnen Beschichtungen und anderen Werkstoffen, die zur Anwendung in der Raumfahrt vorgesehen sind, bewertet wird.
Folgende Werkstoffe und Verbindungen können mit diesem Verfahren untersucht werden:
3 organische Beschichtungen (z. B. Lacke, Anstriche und Kunststoffüberzüge);
3 metallische Überzüge auf Leiterplatten, Zweitflächenspiegeln, Temperaturstrahlern und metallisierten Kunst-stofffolien;
3 kleinere Bauteile (z. B. Solarzellen mit Glasdeckeln).
Assurance produit des projets spatiaux - Mesure de la force d'arrachement des revetements et apprets de rubans auto-adhésifs
La présente Norme européenne présente en détails une méthode d'essai pour laquelle des rubans auto-adhésifs servent a évaluer l'aptitude des revetements, peintures, films et autres matériaux minces destinés a etre utilisés sur le satellite et ses équipements associés.
La méthode d'essai concerne les matériaux et ensembles suivants :
3 revetement organique, par exemple, vernis, peintures et films plastiques ;
3 finitions métalliques sur des circuits imprimés, des SSM (couches thermo-optiques), des radiateurs thermiques, des films plastiques, par exemple ;
3 couches adhésives ;
3 films minces composites ;
3 petits ensembles comme, par exemple, des cellules solaires reliées par des fixations a des protections verre.

EN 14099:2001 (E)4ForewordThis European Standard has been prepared by CMC.This European Standard shall be given the status of a national standard, either by publication of anidentical text or by endorsement, at the latest by April 2002, and conflicting national standards shall bewithdrawn at the latest by April 2002.It is based on a previous version1) prepared by the ECSS Product Assurance Standards Working Group,reviewed by the ECSS Technical Panel and approved by the ECSS Steering Board. The EuropeanCooperation for Space Standardization (ECSS) is a cooperative effort of the European Space Agency,National Space Agencies and European industry associations for the purpose of developing andmaintaining common standards.Requirements in this Standard are defined in terms of what shall be accomplished, rather than in termsof how to organize and perform the necessary work. This allows existing organizational structures andmethods to be applied where they are effective, and for the structures and methods to evolve asnecessary without rewriting the standards.The formulation of this Standard takes into account the existing ISO 9000 family of documents.Annex A is informative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of thefollowing countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,Portugal, Spain, Sweden, Switzerland and the United Kingdom.IntroductionSurface coatings, such as thermal control paints and corrosion protection coatings, are affected, both onthe ground and after launch, by exposure to the environment.It is therefore important that the adhesion of the coating to the relevant substrate remains at anacceptable level after exposure to the relevant environmental condition.1) ECSS-Q-70-13A.SIST EN 14099:2004

Particular attention shall be given to health and safety precautions. Inparticular, hazards to personnel, equipment and materials shall be controlled and minimized.4.2Preparation of samples4.2.1Configurationa)The material samples shall be prepared according to the relevant process specifications ormanufacturer’s data and shall be representative of batch variance.b)If it is not practicable to test completed assemblies, the manufacturer shall submit samples madefrom the same materials and by the same processes as those used in the manufacture of theassemblies.c)The sample for testing shall have clean flat surfaces which do not overlap the sample holderdescribed in 4.4. The width of the test sample surface face shall be at least equal to the width of thetape used in the test procedure. The nominal tape width shall be 20 mm.d)The number of samples to be taken from a qualification batch, test programme, or production batchshall be specified at the start of the test in a material specification. Normally at least ten testsamples shall be tested.e)If it is not practicable to obtain suitable test samples from the finished article, the supplier shallfurnish bonded test samples (samples under strict source to test control, that shall not be usedother than for the designated test) suitable for the tests specified. The supplier shall furnish acertificate of conformance for the purpose of traceability. All test samples shall be marked withappropriate identification to maintain traceability but in such a way as not to degrade the quality ofthe sample during testing.4.2.2CleaningThe cleaning and other treatments of the sample shall be the same as that applied to the finished article,which the sample is intended to represent, prior to integration into the spacecraft. Further cleaning orother treatments shall not be performed.4.2.3Handling and storageSamples shall only be handled with clean nylon or lint-free gloves and shall be stored in a controlledarea, with an ambient temperature of (22 ± 3) °C and relative humidity of (55 ± 10) %. Coated surfacesshall be shielded from contact by using polyethylene or polypropylene bags or sheets. Physical damageshall be avoided by packing the polyethylene or polypropylene-wrapped workpieces in clean, dust- andlint-free material. Limited-life materials shall be labelled with their shelf lives and dates of manufacture,or date of delivery if date of manufacture is not known.4.2.4Identification188.8.131.52MaterialsMaterials submitted for testing shall be clearly identified with appropriate details to maintain traceability.184.108.40.206AssembliesAssemblies submitted for testing shall be...
