Title (German)

Packmittel - Prüfverfahren zur Bestimmung der Porosität der Innenbeschichtung von Aluminiumtuben - Teil 1: Natriumchlorid-Verfahren; Deutsche Fassung EN 15384-1:2017


This European Standard (EN 15384-1:2015) has been prepared by Technical Committee CEN/TC 261 "Packaging", the secretariat of which is held by AFNOR (France). The responsible national standardization committee is Working Committee NA 115-02-08 AA "Tuben" ("Tubes") of DIN Standards Committee Packaging (NAVp). This European Standard is applicable for internally coated cylindrical and conical aluminium tubes, mainly used for the packing of pharmaceutical, cosmetic, hygiene, food or other household products. The internal coating is used as a barrier and should avoid any contact between aluminium and the product. This European Standard defines the sodium chloride method to detect the electrolyte conductivity as one criterion for the quality of the internal coating. The electrolyte conductivity of internally coated aluminium tubes is tested by an enamel conductometer. The aluminium tubes are filled with an electrolyte solution up to a fixed level at its open end. One electrode is connected to the tube nozzle, the second electrode is dipped into the solution. A defined voltage is applied for a fixed time. The induced current is a measure for the quality (pores and/or film thickness) of the internal coating.
