Copper and copper alloys - Combustion method for determination of the carbon content on the inner surface of copper tubes or fittings

This European Standard specifies a combustion method for determining the carbon content, if any, on the
inner surface of tubes of copper or fittings of copper or copper alloys.
This standard applies only to seamless, round copper tubes as specified for example in EN 1057 and
EN 13348 or fittings of copper or copper alloys as specified in EN 1254 (all parts).

Kupfer und Kupferlegierungen - Verfahren zur Bestimmung des Kohlenstoffgehaltes auf der Innenoberfläche von Kupferrohren oder Fittings durch Verbrennen

Diese Europäische Norm legt ein Verbrennungsverfahren zur Bestimmung des Kohlenstoffgehaltes, sofern
vorhanden, auf der Innenoberfläche von Rohren aus Kupfer oder Fittings aus Kupfer oder Kupferlegierungen
fest.
Diese Norm ist nur auf nahtlose, runde Kupferrohre, wie z. B. in EN 1057 und EN 13348 oder auf Fittings aus
Kupfer wie in EN 1254 (alle Teile) festgelegt, anzuwenden.

Cuivre et alliages de cuivre - Méthode de détermination par combustion de la teneur en carbone à la surface interne des tubes ou des raccords en cuivre

La présente Norme européenne spécifie une méthode de combustion pour la détermination de la teneur en carbone éventuellement présent sur la surface interne des tubes ou des raccords en cuivre ou en alliages de cuivre.
La présente norme ne s'applique qu'aux tubes ronds en cuivre, sans soudure, spécifiés par exemple dans l'EN 1057 et l'EN 13348 ou aux raccords en cuivre ou en alliages de cuivre spécifiés par l’EN 1254 (toutes parties).
