14、N 13973:2002 (E) Foreword This document EN 13973:2002 has been prepared by Technical Committee CENTTC 261 “Packaging“, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at
15、the latest by April 2003, and conflicting national standards shall be withdrawn at the latest by April 2003. According to the CENICENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Repub
16、lic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom, 3 EM 13973:2002 (E) D n trod uction The purpose of packaging is the containment, protection, distribution and promotion of pro
17、ducts. 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 residual product waste. 4 EN 139732002 (E) 1 Scope This European Standard specif
18、ies a method for determination on the drainability of plastic bottles and jars with a nominal capacity up to 5 I and of plastics canisters/jerricans with a nominal volume up to 20 I. NOTE Plastics bottles, jars, canisters and jerricans are referred to as “containers” in this standard. 2 Normative re
19、ferences 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 listed hereafter. For dated references, subsequent amendments to or revisions of any of
20、 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). EN 13974, Rigid plastics containers - Specification of tolerance for dimensions, weight
21、and volume. 3 Terms and definitions For the purposes 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 plastics bottle rigid plastics container with shoulders and a small aperture, and generally
22、 blow moulded EN 13974:2002 3.2 plastics jar rigid plastics container of any base shape, with an aperture of area similar to that of the base EN 13974:2002 3.3 plastics canisterljerrican rigid plastics container with mostly rectangular or circular section NOTE An aperture on the top or side of the b
23、ody and a carrying device is usual. EN 13974:2002 3.4 nominal capacity capacity for which the container is designed 3.5 drainability quantitive measure of the residual content of a container emptied afer its normal use 3.6 absolute drainability the residual content of the test liquid expressed in g
24、5 EN 13973:2002 (E) 3.7 relative drainability the residual content expressed as a percentage of the nominal capacity 4 Principle Obtaining the mass of the chosen test liquid left as a residue in the container after drainage under gravity. 5 Sampling The test shall be performed on a predetermined num
25、ber of containers which shall be representative of the consignment. 6 Apparatus 6.1 Balance Balance with an accuracy of at least 0,l YO 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 of f I “C. 6.3 Testing l
26、iquids 6.3.1 Normal tap water Normal tap water, not distilled and without any additional additives, with temperature of 23 “C f 1 “C. 6.3.2 Another test liquid Another test liquid of choice with defined characteristics. 6.4 Holding device for the container Holding device for the container, which wil
27、l enable 7.7 to be carried out if required. 7 Procedure 7.1 Place the empty container with its normal closure on the balance (6.1) and record its mass in g. 7.2 Fill the container to at least 50 % of its nominal capacity with the test liquid (6.3) and close the container. 7.3 Remove any liquid from
28、the outside surface of the container. 6 EN 13973:2002 (E) 7.4 Agitate the container to ensure that the entire inner surface is exposed to the liquid. 7.5 Open the container and empty it unti; the liquid flow stops. 7.6 Slowly incline the container up to the angle which ensures optimal draining. Leav
29、e the container in this position for a further 1 min without moving or shaking it. . 7.7 Re-weigh the emptied container with its closure and record the mass in g. 8 Calculation 8.1 Absolute drainability Calculate the absolute drainability, in g, by subtracting the mass of the empty container (7.1) f
30、rom the mass of the container after emptying (7.7). 8.2 Relative drainability Calculate the relative drainability, in %, from the ratio of absolute drainability to nominal capacity (the mass of the test liquid, in g) multiplied by 100. 9 Testreport The test report shall include the following informa
31、tion: a) a reference to this European Standard; b) a description of the container (.e. design, name, supplier etc.) and type of plastics material; c) the date of the test; d) the number of replicates tested; e) the nominal capacity of the container; 9 the cavity number, if applicable; g) the chosen
32、test liquid, together with its characteristics; h) the test temperature; i) the absolute drainability of each container; j) the relative drainability of each containers tested; k) the average absolute drainability of all container tested; I) the average relative drainability of all containers tested
33、; 7 EN 13973:2002 (E) m) a report on the sampling procedure used; n) the name and signature of the person conducting the test. 8 BS EN 13973:2002 BSI 389 Chiswick High Road London w4 4AL -a“Tw- a&- 21BXx2%mexm,-s BSI - British Standards Institution BSI is the independent national body responsible fo
