BS EN 13048:2009EN 13048:2009 (E) 4 1 Scope This document specifies a method for

15、the determination of the thickness of the lacquer film applied inside cylindrical and conical aluminium tubes. The method is a reference. It can also be used as a reference when calibrating other electronic instruments suitable for determining coating weight thickness, e.g. by capacitance measuremen

16、t by eddy current. It is applicable to aluminium tubes used for packing pharmaceutical, cosmetic, hygiene, food and other domestic products. NOTE Although not specified in this standard there are available suitable automatic film thickness measurement instruments that provide instantaneous results w

19、 terms and definitions given in EN 12374:1998 and EN ISO 2360:2003 apply. 4 Principle The measurement of the thickness of the lacquer film inside aluminium tubes with a micrometer or dial indicator after separation of the film from the aluminium tube and its enamel decoration by chemical means. Thro

20、ugh a chemical reaction the aluminium is dissolved and hydrogen gas is generated. The internal lacquer film remains intact. 5 Apparatus 5.1 Test measuring and other equipment a) Micrometer or dial indicator giving a precision of 0,001 mm (1 m); b) Oven; c) Extractor fan; d) Glass container of a size

21、 capable of containing a tube cut as in Figure 1; e) Scissors; f) Tweezers; BS EN 13048:2009EN 13048:2009 (E) 5 g) Filter paper; h) Protective clothing and glasses. 5.2 Chemical Agents a) Solvent capable of dissolving the external enamel of the tubes; b) Sodium hydroxide with a concentration of 20 g

22、 of NaOH/100 ml. NOTE Hydrochloric acid at a concentration of 10 g HCI/100 ml may be used instead of sodium hydroxide. 6 Method 6.1 Preliminary Precautions The preparation of samples requires the handling and use of hazardous materials. This document does not purport to address all of the safety pro

23、blems associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use. 6.2 Preparation of Samples a) Cut the tubes with the scissors as shown in Figure 1 (all

24、 measurements in mm). b) Dissolve the external enamel with the solvent. c) Pour NaOH solution into the container in a quantity sufficient to cover the tube. d) Place the container under the extract fan. e) Immerse the tube in the NaOH solution. f) With the tweezers remove the lacquer film and rinse

25、with water. g) Dry the film between two sheets of filter paper. Then place the film in the oven for 1 h at 80 C. 6.3 Measurement procedure After cooling, the thickness of the lacquer film is measured at a temperature of between 10C and 25C with the micrometer. These measurements shall be taken at th

28、s at the different points of measurement; g) number of samples checked; h) number of defects. A defect is any tube with an internal lacquer film thickness that falls outside the specified or agreed limits (see 7a); i) if necessary, acceptance or refusal of the batch depending on the specifications (
