16、DARDS, 14/05/2008 02:13, Uncontrolled Copy, (c) BSIEN 15421:2007 (E) 4 1 Scope This standard specifies a method for the determination of the adhesion of the internal and external protective lacquer of aluminium tubes. It is applicable to aluminium tubes that are coated with an internal or external p
17、rotective 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 a defined extent and under defined temperature conditions to create a standardized and sharp-edged defor
18、mation 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).

20、e tests are carried out at a temperature between (23 5) C. For testing the adhesive strength 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
21、be done immediately after taking the samples out of the refrigerator. 5 Procedure Insert the 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 b
22、ody length. Remove the crushed tube from the compressing device and stretch it again in the axial 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 Te
23、st report 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 and the dimensions of the samples
