This European Standard shall be given the status of a national standard, either by public

16、ation of an identical text or by endorsement, at the latest by April 2003, and conflicting national standards shall be withdrawn at the latest by April 2003. According to the CENKENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this

17、European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. 3 EN 13972:2002 (E) Introduction The purpose of packaging is the containment,

18、protection, distribution and promotion of products. A major role is prevention of product damage and/or product waste. This European Standard was developed to test the design of a container and to provide requirements and test procedures to meet recommendations on capacities. 4 EN 13972:2002 (E) 1 S

19、cope This European Standard specifies a gravimetric method for determining the bnmfui and total capacities of plastic bottles and jars up to 5 I, of plastic canistersljerricans with a nominal volume up to 20 I and of plastic pails with a nominal volume up to 60 I. NOTE Plastics bottles, jars caniste

20、rsijerricans and pails 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 references are cited at the appropriate places in the text, and the publications are

21、listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies (including amendments). E

22、N 13974, Rigid plastics containers - Specification of tolerance for dimensions, weight and volume. 3 Terms and definitions For the purpose of this European Standard, the terms and definitions given in EN 13974:2002 (some of which are repeated below for convenience) and the following apply. 3.1 plast

23、ics bottle rigid plastics container with shoulders, with a small aperture and generally blow-moulded EN 13974:2002 3.2 plastics jar rigid plastics container of any base shape, with an aperture with an area similar to that of the base EN 13974:2002 3.3 plastics canisterljerrican rigid plastics contai

24、ner with mostly rectangular or circular section NOTE EN 13974:2002 An aperture on the top or side of the body and 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 container has a lid with or without a l

25、eak proof seal and is generally nestable EN 13974:2002 3.5 nominal capacity capacity for which the container is designed 5 EN 13972:2002 (E) 3.6 brimful capacity volume of water in litres held by the container when filled through the filling orifice to the point of overflowing 3.7 total capacity tot

26、al internal volume of the closed container 4 Principie Calculation of the capacities of a plastic container from the mass of the water filling the container. 5 Sampling The test shall be performed on a predetermined number of containers which shall be representative of the consignment. NOTE Containe

27、rs and closures should be tested not earlier than 48 h after production. 6 Apparatus 6.1 Balance Balance with an accuracy of at least 0,l % of the weight being measured 6.2 Thermometer Thermometer, with a scale range graduated in increments of no more than 1 “C, with an accuracy off 1 “C. 6.3 Device

28、 Device, to make two holes in the container or lid. 6.4 Testing liquid Testing liquid, normally tap water at 23“ C f 1 C, water at other temperatures may be used by agreement but with the same tolerance. NOTE The temperature range has been limited to I1 “C because tests have shown that the expansion

29、 of plastic containers cannot be neglected if broader temperature ranges are used. 7 Procedure for the measurement of brimful capacity 7.1 Expression of results Measurement of the brimful capacity shall be in accordance with 7.2 to 7.8. 7.2 Determine the mass of each empty container without the clos

30、ure or lid and record the values in g. 7.3 Stand the container on the balance. 7.4 Fill the container with water at the test temperature until it begins to overflow. 7.5 Remove any water that has overflowed onto the outside surface of the container or the balance. 6 EN 13972:2002 (E) 7.6 Record the

31、mass in g and temperature of the filled container. 7.7 container in g. 7.8 Calculate the mass of the water by subtracting the mass of the empty container from the mass of the filled Determine the brimful capacity in accordance with clause 7. 8 Procedure for the measurement of total capacity 8.1 Expr

32、ession of results Measurement of the total capacity shall be in accordance with 8.2 to 8.9. 8.2 Preparation a) For bottlesljars, use the container and closure; b) for canisters/jerricans, use the container and closure, drilling two holes in the highest place of the container; c) for pails, use the c

33、ontainer and lid, drilling two holes in the lid of the container on a line from the outer rim to the centre of the lid. 8.3 Determine the mass of each empty container including the closure/lid and record the values in g. 8.4 Fill the empty container with water at the test temperature: a) for bottled

34、jars, fill to total capacity; b) for canisters/jerricans, using one of the two drilled holes in the highest position possible, fill until the water runs out of the second hole. Ensure that all entrained air is removed. Then continue to fill to total capacity; c) for pails, using one of the two drill

35、ed holes fill until the water runs out of the second hole. Ensure that all entrained air is removed. Then continue to filling to total capacity. 8.5 Seal the container: a) for bottles/jars, replace the closure; b) for canisters/jerrican s, seal the holes with a tape of negligible mass; c) for pails,

36、 seal the holes with a tape of negligible mass. 8.6 Remove any surface water from the outside of the container. 8.7 8.8 container g. Place the container on the balance and record the mass of the filled container in g and the temperature. Calculate the mass of the water by subtracting the mass of the

37、 empty container from the mass of the filled 8.9 Determine the total capacity in accordance with 8. 9 Calculation of capacities 9.1 General The capacity of the container shall be expressed in millilitres or litres to three significant figures, and is calculated from the difference between the mass o

38、f the filled and empty container. 7 EN 139722002 (E) 9.2 Determine the capacity by using the equation Capacity = m x VCF Where m VCF is the measured mass of water, in grams is the Volume Correction Factor for water at the test temperature. Volume Correction Factors for water at 23 OC: = 1,002 47“ NO

39、TE 9.3 Example of a calculation: Test temperature = 23 “C Mass of water Capacity A list of correction factors for the range 12C to 30C is given in Table 1 of EN IS0 9021999 2. = 5 500 g = 5 500 x 1,002 47 = 5 513,585 ml = 5 510 ml or 551 I IO Test report The test report shall include the following i

40、nformation: a) a reference to this European Standard; b) a description of the container (.e. design, name, supplier etc.) and type of plastics material: c) conditioning status, if there is any conditioning requested for the process and material used. EXAMPLE Time between manufacture and measurement,

41、 annealing processes etc. a report of the sampling procedure used; the date of the test: the number of replicates tested; the nominal capacity of the container; the cavity number, if applicable; the average result of all containers tested: the brimful and/or total capacity of each container; identif

42、ication of containers which did not satisfy the specified requirements, if any; temperature of the water used for the capacity determination; a calculation to ascertain whether the containers comply with the acceptance criteria, if any; the name and signature of the person conducting the test.
