EN 15421:2007 (E) 4 1 Scope This standard specifies a method for the determination of the adhesion of the internal and external protective lacqu

    15、er of aluminium tubes. It is applicable to aluminium tubes that are coated with an internal or external protective lacquer and which are used for packing, e.g. pharmaceutical, cosmetic, hygiene, food and other household products. 2 Principle By means of a compressing device the tube is compressed to

    16、 a defined extent and under defined temperature conditions to create a standardized and sharp-edged deformation of the tube. The kinks are checked visually for any cracks and/ or delamination of internal or external lacquer. 3 Apparatus Compressing device according to Figure 1 (example). EN 15421:20

    17、07 (E) 5 Key 1 Compressing clamp 2 Guide pin (for tubes diameter 19 mm = 8 mm, for tubes diameter 19 mm = 15 mm) 3 Guide bolt 4 Base plate 5 Tube Figure 1 Test device EN 15421:2007 (E) 6 4 Test conditions The tests are carried out at a temperature between (23 5) C. For testing the adhesive strength

    18、of inner and outer protective lacquers of products stored or used under cold conditions, (5 + 3) C, the samples have to be stored under the same conditions for at least 2 h prior to testing. The test has to be done immediately after taking the samples out of the refrigerator. 5 Procedure Insert the

    19、tube in the compressing device. In order to keep the tube straight during compression an internal guide pin should be used. Compress the tube until the tube body is reduced to (15 5) % of the original tube body length. Remove the crushed tube from the compressing device and stretch it again in the a

    20、xial direction. Check the stretched tubes for cracked and detached lacquer parts of the inner and outer protective lacquering. If there are any cracks or detached lacquer parts, the samples have failed. 6 Test report The test report shall contain the following information: a) Reference to this stand

    21、ard 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 and the dimensions of the samples. d) Nature of the internal and external protective lacquering. e) Test temperature. f) Numbe

    22、r of samples checked. g) Number and description of defects. h) If necessary, acceptance or refusal of the batch depending on the specifications. i) All factors which could have affected the results or all operating details not specified in this standard. j) Date, place of test and name of tester.
