(Main)Adhesives - Determination of hydroxyl value and/or hydroxyl content
Adhesives - Determination of hydroxyl value and/or hydroxyl content
This European Standard specifies a method to determine the hydroxyl value and/or the hydroxyl content of adhesives, adhesive components, their basic constituents and related products. This method can also be used to determine the hydroxyl value and/or the hydroxyl content of surface protection systems of concrete.
Klebstoffe - Bestimmung der Hydroxylzahl und/oder des Hydroxylgehaltes
Diese Europäische Norm legt ein Verfahren zur Bestimmung der Hydroxylzahl und/oder des Hydroxylgehaltes von Klebstoffen, Klebstoff-Komponenten, ihren Grundbestandteilen sowie verwandter Produkte fest. Dieses Verfahren darf auch zur Bestimmung der Hydroxylzahl und/oder des Hydroxylgehaltes von Beton-oberflächenschutzsystemen verwendet werden.
Adhésifs - Détermination de la valeur hydroxyle et/ou de la teneur en hydroxyle
La présente Norme européenne spécifie une méthode de détermination de la valeur hydroxyle et/ou de la teneur en hydroxyle des adhésifs, des composants d'adhésifs, de leurs constituants de base et des produits connexes. Cette méthode peut également être utilisée pour déterminer la valeur hydroxyle et/ou la teneur en hydroxyle des systèmes de protection de surface du béton.
Lepila - Določevanje hidroksilnega števila in/ali hidroksilnih skupin
Ta evropski standard opredeljuje metodo za določevanje hidroksilnega števila in/ali hidroksilnih skupin lepil, komponent lepil, njihovih osnovnih sestavin in sorodnih proizvodov. Ta metoda se lahko uporablja tudi za določevanje hidroksilnega števila in/ali hidroksilnih skupin betonskih sistemov za površinsko zaščito.
