Description

Verfahren zum Erkennen von Undichtigkeiten an Vakuumgefäßen und Vakuumapparaten Gemäß der Erfindung ist für die Ausübung des Verfahrens nach dem Patent 503073 Ammoniak als Gas und Mercuronitrat als Indikator zur Erkennung von Undichtigkeiten an Vakuumgefäßen und Vakuumapparaturen besonders geeignet.Method for detecting leaks in vacuum vessels and vacuum apparatuses According to the invention, ammonia as a gas and mercuronitrate as an indicator for detecting leaks in vacuum vessels and vacuum apparatuses are particularly suitable for carrying out the method according to patent 503073.

Das Verfahren wird zweckmäßig so ausgeführt, daß Vakuumgefäße oder die Teile von solchen, welche auf Dichtigkeit geprüft werden sollen, auf der einen Seite ihrer Wandung einem überdruck von Ammoniak ausgesetzt und auf der Gegenseite mit einem Anstrich versehen oder mit einem vorzugsweise weißen. Tuch oder Papier bekleidet werden, welche den Indikator enthalten.The method is expediently carried out so that vacuum vessels or the parts of those that are to be checked for leaks on the one hand Side of its wall exposed to an overpressure of ammonia and on the opposite side painted or preferably white. Cloth or paper that contain the indicator.

Die Prüfung kann kurzzeitig sein oder aber mehrere Stunden bis Tage in Anspruch nehmen, je nach dem Grad von Dichtigkeit, der festgestellt werden soll.The exam can be short-term or several hours to days depending on the degree of tightness that is to be determined.
