Aerospace series - Organic compounds - Test method - Analysis by infrared spectroscopy

This test method describes the principles applicable to infrared transmission spectrophotometric analysis of organic compounds (elastomers, basic resins, resin mixes or resin systems) used as the matrix in reinforced polymers, adhesives, bonding primers and, in general terms, all organic compounds.
The method could also be applied to some inorganic products.
It is intended to be used jointly with special test conditions specified in the materials specification invoking the test.
This document does not give any directions necessary to meet the health and safety requirements. It is the responsibility of the user of this document to adopt appropriate health and safety precautions.

Luft- und Raumfahrt - Organische Verbindungen - Prüfverfahren - Analyse durch lnfrarot-Spektroskopie

Dieses Dokument legt das Prüfverfahren fest, das die Grundlagen für die infrarot-spektrophotometrische Analyse von organischen Verbindungen (Elastomere, Basisharze, Harzgemische oder Harzsysteme) beschreibt, die als Matrix in verstärkten Polymeren, Klebstoffen, Haftgrundmitteln und allgemein in allen organischen Verbindungen verwendet werden.
Das Verfahren könnte auch bei bestimmten anorganischen Stoffen angewendet werden.
Es wird vorausgesetzt, dass es in Verbindung mit speziellen, in der Werkstoffnorm, die dieses Verfahren anführt, festgelegten Prüfbedingungen angewendet wird.
Dieses Dokument enthält keine Anweisungen in Bezug auf die einzuhaltenden Gesundheits- und Sicherheitsanforderungen. Es ist die Verantwortung des Anwenders dieses Dokuments, die jeweils erforderlichen Gesundheits- und Sicherheitsvorkehrungen zu treffen.

Série aérospatiale - Composés organiques - Méthode d'essai - Analyse par spectroscopie infrarouge

La présente méthode d’essai décrit les principes applicables à l’analyse spectrophotométrique par transmission infrarouge des composés organiques (élastomères, résines basiques, mélanges de résines ou systèmes de résines) utilisés comme matrice dans les adhésifs, les apprêts de liaison et les polymères renforcés et, de manière générale, dans tous les composés organiques.
Cette méthode est également susceptible d’être appliquée à certains produits inorganiques.
Elle doit être utilisée conjointement avec les conditions d’essai particulières définies dans la spécification des matériaux faisant appel à l’essai.
La présente norme ne donne pas les instructions nécessaires au respect des exigences en matière de santé et de sécurité. Il est de la responsabilité de l'utilisateur d'adopter les précautions appropriées liées à la santé et la sécurité.

Aeronavtika - Organske spojine - Preskusna metoda - Analiza z infrardečo spektroskopijo

Ta preskusna metoda opisuje načela, ki veljajo za analizo z infrardečo transmisijsko spektroskopijo organskih spojin (elastomerov, osnovnih smol, mešanic smol ali sistemov smol), ki se uporablja kot matrica v armiranih polimerih, lepilih, veznih osnovnih premazih in splošno v vseh organskih spojinah.
To metodo je mogoče uporabiti tudi za nekatere anorganske produkte.
Namenjena je za uporabo skupaj s posebnimi preskusnimi pogoji, ki so določeni v specifikacijah materiala, ki se ga preskuša.
Ta dokument ne vsebuje smernic, potrebnih za izpolnjevanje zdravstvenih in varnostnih zahtev. Uporabnik tega dokumenta je odgovoren, da sprejme ustrezne zdravstvene in varnostne ukrepe.
