20、closures for flexible tubes. It is applicable to flexible single-layer metal or plastics tubes, and multilayer or laminated tubes, used for packing pharmaceutical, cosmetic, hygiene, food and other domestic and industrial products. 2 Definitions For the purposes of this standard, the definitions giv
21、en in prEN 12374 apply. 3 Principle The detection of air bubbles escaping from the cap, when the tube is held under water and subjected to an internal air pressure of 0,25 bar. 4 Apparatus 4.1 Air compressor, with an initial minimum pressure of 2 bar, equipped with an air regulator allowing a consta
22、nt and stable pressure of (0,250,01) bar. 4.2 Manometer, accurate to 0,01 bar. 4.3 Conical connector, adapted to the diameter of the tube, which allows the attachment of the open end of the tube to the compressed air source without leaks. 4.4 Transparent glass container, of a size such as to allow t
23、he head of the tube to be immersed in water. 5 Procedure The test shall be carried out on the capped tube at an ambient temperature of between 10 8C and 25 8C. Attach the open end of the tube to the compressed air source with the conical connector (see Figure 1). Set the air regulator so as to maint
24、ain an air pressure of (0,250,01) bar inside the tube. Immerse the head of the tube in the water, ensuring that the cap is totally immersed for at least 3 s. The tube is considered defective if a continuous stream of bubbles is seen throughout the test period. Licensed Copy: sheffieldun sheffieldun,
