EN 14401:2004 (E) 4 1 Scope This European Standard specifies a method for testing the effectiveness of the seals of closures on plastic bottles and jars up to 5,0 l, of plastics canisters/jerricans with a nominal volume up to 20 l and

18、of plastic pails with a nominal volume up to 60 l. NOTE Plastics bottles, jars, canisters and jerricans are referred to as “containers” in this standard. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative refe

19、rences are cited at the appropriate places in the text, and the publications are listed hereafter.

21、some of which are repeated below for convenience) and the following apply. 3.1 plastics bottle rigid plastics container with shoulders and a small aperture, generally blow moulded 3.2 plastics jar rigid plastics container of any base shape, with an aperture of area similar to that of the base 3.3 pl

22、astics canister/jerrican rigid plastics container with mostly rectangular or circular section NOTE An aperture on the top or side of the body and a carrying device is usual. 3.4 pail rigid plastics container of any shape, the top of which is greater than or equal to the area of the bottom. The conta

23、iner has a lid with or without a leak proof seal and is generally nestable 3.5 hydrostatic force force exerted on a defined area inside a container, by the weight of liquid above it 3.6 closure system of one or more components which, when fitted to an opening of a container, prevents any contents of

24、 the container from escaping through the opening under defined conditions of test 3.7 effectiveness of a closure ability of a closure to prevent any contents of a container from escaping through the opening to which it is fitted, under defined conditions of test 4 Principle Applying pressure to the

25、contents of a container, either by a hydrostatic force, or vacuum applied to the outside of the container to test for leakage past the closure. EN 14401:2004 (E) 5 5 Sampling The test shall be performed on a predetermined number of containers which shall be representative of the consignment. 6 Testi

26、ng fluid 6.1 Original content Original liquid used to fill the container 6.2 Alternative testing liquid An alternative testing liquid using the following mixture may be used: 1) 50 g non ionogen Tenside, 2) 950 ml distilled water 3) Rhodamin as colourant 7 Test procedure 7.1 Method Examination of ti

27、ghtness can be done by either or both of the methods described in 7.4. 7.2 Filling Fill the containers to their nominal capacity with the liquid specified in 6.1 or 6.2 and fit the closure. Screw caps shall be closed to the torque specified, if any. 7.3 Conditioning After filling, lay the containers

28、 on their side with the closure below the level of the liquid for 24 h at a temperature between 18 C and 28 C NOTE Containers and closures should be tested not earlier than 72 h after production. Plastics containers can change their dimensions after production and in subsequent use. 7.4 Testing 7.4.

29、1 Method 1 Place the containers upside down for 24 h at a temperature between 18 C and 28 C. 7.4.2 Method 2 Lay the containers on their side with the closure below the level of the liquid for 10 min at a temperature between 18 C and 28 C in a vacuum chamber, having a vacuum of 600 mbar. 7.5 Detectio

30、n of leakage The containers shall be placed on a surface of a type that will assist the observation of any leakage from the closure. EN 14401:2004 (E) 6 NOTE White paper of suitable quality to resist any applied vacuum has been found suitable when using the liquid defined in 6.2. 7.6 Pass criteria T

31、he closure is deemed to have passed the test if no leakage is detected. 8 Test report The test report shall include the following information: a) a reference to this European Standard; b) a description of the container and closure system (i.e. design, name, supplier etc.) and type of plastics materi
