Aerospace series - Paints and varnishes - Test method for determination of phosphoric acid index

This European Standard specifies a method for the titration and determination of the phosphoric acid content of an hydroalcoholic solution for aerospace applications.
This test method is relevant for the determination of total acidity and phosphoric acid content in a reactive thinner of a wash primer or in metal cleaners.

Luft- und Raumfahrt - Anstrichstoffe - Prüfverfahren zur Bestimmung des Phosphorsäure-Index

Diese Europäische Norm legt ein Verfahren zur Titration und Bestimmung des Phosphorsäuregehaltes einer wässrig-alkoholischen Lösung für Anwendungen in der Luft- und Raumfahrt fest. Dieses Prüfverfahren ist für die Bestimmung der Gesamtsäurezahl und des Phosphorsäuregehaltes in einem reaktiven Verdünner eines Washprimers (Haftgrundmittels) oder in Metallreinigern von Bedeutung.

Série aérospatiale - Peintures et vernis - Méthode d'essai pour la détermination de l'indice d'acide phosphorique

Aeronavtika - Barve in laki - Preskusna metoda za ugotavljanje indeksa fosforne kisline

Ta evropski standard določa metodo za titracijo in ugotavljanje vsebnosti fosforne kisline v vodno-alkoholni raztopini za uporabo v aeronavtiki.
Preskusna metoda je primerna za ugotavljanje skupne kislosti in vsebnosti fosforne kisline v reaktivnem razredčevalcu čistilnega sredstva za pripravo površine ali v čistilih za kovino.
