DIN EN 15384-1:2017-04 EN 15384 -1:2017 (E) 4 1 Scope This European Standard is applicable for internally coated cylindrical and conical aluminium tubes, mainly used for the

19、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 standard defines the sodium chloride method to detect the electrolyte conductivity as one criterion for the q

20、uality of the internal coating. NOTE The electrolyte conductivity of the internal coating is only one criterion for evaluation of the quality of an internal coating. It does not give any information on the quantity or size of any pores or uncoated areas, nor any hint on possible reactions between th

21、e aluminium tube and the product. The electrolyte conductivity should never be used as the sole criterion for quality evaluation of the internal coating, but always with other parameters e.g. film thickness, acetone and/or ammonia resistance and of course results of enhanced stability studies. 2 Pri

22、nciple 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 solut

23、ion. 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. 3 Apparatus 3.1 Enamel conductometer 3.2 Moveable electrode 3.3 Electrolyte NOTE A schematic diagram of the test equipment is given in Figure 1.

Depending on the method and the kind of apparatus (different apparatus are available) specific adjustments and calibrations may be necessary and should be done as described in the user manuals prior to use. To take

29、 a measurement put the tube into the adapter electrode, ensuring there is an electric circuit between the tube and electrode. Insert the dipping electrode centrally into the tube until it touches the tube shoulder, avoiding any contact between the tube wall / tube shoulder and the dipping electrode.

30、 Fill the tube with electrolyte up to 10 mm from the end after inserting the electrode. Start the measurement application of voltage immediately. Read the result in mA on the display after the measuring interval. The electrolyte can be used for testing 10 tubes. Measurements on one tube are repeatab

For tubes with special conification angles and nozzles, e.g. without membrane or cannula, higher tolerance limits may be requi

32、red. In addition, for some specific internal coatings but also depending on the product, different tolerance limits may be required. Any deviations from this standard shall be agreed mutually between both parties. Tolerances for the sodium chloride method are given in Table 2: Table 2 Tolerances for

NOTE 2 The tolerances given in Table 2 are only valid for standard tubes and not for tubes with additional treatment such as sterilization. 6 Test report Unless otherwise agreed between both parties

35、 the test report shall contain the following information: a) reference to this standard and if necessary a specification for the method of sampling and acceptance of the batch, b) complete identification of the batch and of the tubes checked, c) description of the samples, d) registering number of t
