DIN EN 15653:09-07 This document (EN 15653:2009) has been prepared by Technical Committee CEN/TC 261 “Packaging”, the EN 15653:2009 (E) 4 1 Scope The ammonia test is a qui
15、ck test to check the chemical resistance of the internal protective coating of aluminium tubes. The test is used for flexible aluminium tubes for ammonia containing fillings and as an introductory test for newly developed internal protective coatings. 2 Test device / media - Aqueous solution of ammo
16、nia with a mass fraction of (20-25)% inclusive; - Ventilated hood; - Test tubes and special holder; - Rack; - Scissors; - Protective glasses. 3 Test operation Stand the samples on the tube cap, fill them with the test solution under the ventilated hood and put open into a rack. Immediately cover the
17、 open ends of the tubes. After a storage period of 2 h at room temperature empty the test solution from the test samples into the test tubes. Rinse the samples with water and carefully cut open with the scissors. 4 Evaluation of the internal coating The internal protective coating shall not show any
18、 large blisters or softening (scratch test). Occasional blisters (up to a diameter of 5 mm) and detachment of the internal protective coating at the cut edges are of no concern and can therefore be accepted. 5 Test report The test report shall contain the following information: a) reference to this
19、standard; b) complete identification of the batch and of the tubes checked; c) description and dimensions of the samples; d) nature of the internal protective coating; e) concentration of the ammonia solution; f) test results, including the number of defects; g) number of samples checked; h) if necessary, acceptance or refusal of the batch depending on the specifications; i) all factors which can have affected the results and which are not specified in this standard; j) date, place of test and name of tester.
