15、SI 19971 BS 7864 : 1997 Specification Introduction This British Standard specifies requirements for plastics containers intended primarily for paints and other products of the surface coatings industry. An equivalent standard, BS 1262, specifies requirements for round metal containers with lever lid
16、s for paints and other products of the surface coatings industry. 1 Scope This British Standard specifies requirements, applicable at the time of supply, for a range of plastics containers, with nominal volumes between 125 ml (millilitres) and 10 l (litres), intended primarily for paints and other p
17、roducts of the surface coatings industry. Performance requirements and related methods of test are described covering freedom from leaks, stacking strength, anti-static properties, handle strength and lid security. NOTE 1. Compliance with this standard does not in itself imply suitability for the pu
18、rpose for which the container is used. NOTE 2. Where paints or other products are classed as hazardous, the package will be required to conform to the appropriate supply or carriage regulations. This may require performance testing and certification of packages. 2 References 2.1 Normative references
19、 This British Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are made at the appropriate places in the text and the cited publications are listed on the inside back cover. For dated references, only the edition cited applies; any
20、subsequent amendments or revisions of the cited publication apply to this British Standard only when incorporated in the reference by amendment or revision. 2.2 Informative references This British Standard refers to other publications that provide information or guidance. Editions of these publicati
21、ons current at the time of issue of this standard are listed on the inside back cover, but reference should be made to the latest editions. 3 Definitions For the purposes of this British Standard, the following definitions apply. 3.1 supply Transfer of goods from the supplier to the customer. NOTE.
22、In some circumstances, supply can be the point of transfer of ownership, to be agreed between the customer and supplier. 3.2 ullage Gross lidded capacity minus the nominal volume. 3.3 package The unit that is liable to be individually handled, including the receptacle in which goods are carried, the
23、 contents and any associated packagings, e.g. components, materials or wrappings for the purpose of enabling it to perform its containment function. 4 Dimensions and ullage NOTE. Recommended dimensions for round, cylindrical, lever-lid containers are given in annex A. The gross lidded capacity shall
24、 be determined in accordance with annex B. The minimum ullage space shall be 8 % of the nominal volume. 5 Materials and construction 5.1 Materials Except where the inclusion of such recyclate material would degrade or otherwise adversely affect the contents, plastics containers shall be manufactured
25、 in such a way that cleaned, post-consumer recyclate is able to be incorporated with virgin material at a level that maintains performance characteristics. NOTE 1. To aid recyclability, all components of a container should be made from the same generic material where practical. All components should
26、 carry the appropriate identification marks, e.g. in accordance with BS 7746. NOTE 2. All material used in the manufacture of plastics containers should be compatible with the intended contents and suitable for the intended end use. Recommendations on the information to be agreed between the purchas
27、er and the supplier to ensure compatibility are given in annex C. Licensed Copy: London South Bank University, London South Bank University, Fri Dec 08 13:14:12 GMT+00:00 2006, Uncontrolled Copy, (c) BSI 2 BSI 1997 BS 7864 : 1997 5.2 Construction Plastics containers shall be constructed and supplied
28、 so as to ensure the following. a) They shall be suitable for normal conditions of filling, storage, transport and use without suffering undue damage, collapse, leakage or detriment to the external appearance or decoration. b) They shall be able to accept the agreed form of decoration. If printed, c
29、ontainers shall exhibit print adhesion of a minimum of 90 % and print hardness of a minimum of B grade pencil when tested in accordance with annex D. The print integrity shall be such that the degree of legibility remains acceptable when tested in accordance with annex E. c) They shall show suitable
30、 resistance to static charge build-up to avoid dust attraction and/or fire hazard. NOTE 2. See annex F for recommendations on determining surface electrostatic properties. NOTE 3. The use of plastic containers in a flammable atmosphere may pose a fire or explosion risk due to the generation of stati
31、c electricity. Such undesirable static electricity should be controlled in accordance with BS 5958. d) They shall show suitable resistance to environmental stress cracking by conforming to BS 2782 : Part 8 : Method 832A. 6 Performance 6.1 Freedom from leaks When tested in accordance with either of t
32、he methods in annex G, the container shall be judged to be leak-free. 6.2 Lids 6.2.1 Lid fit When tested in accordance with annex H, the lid shall not be displaced. 6.2.2 Fitting of lids Lids shall be capable of being fitted automatically using conventional systems without container collapse or subs
33、equent lid pop-off. The necessary closing force for lidding shall not exceed 2.4 kN applied for not more than 0.5 s. 6.2.3 Nesting characteristics Lids shall exhibit non-locking nesting characteristics. NOTE. Lids stacked as supplied should be capable of being loaded into conventional systems withou
34、t the stacks collapsing. 6.2.4 Opening Lever-lid containers shall be openable using a 10 mm flat bladed screwdriver without damaging or distorting the container. NOTE. Where an opening tool is provided, this should be used. 6.2.5 Refitting The lid shall be capable of being re-fitted manually twice f
35、or continued storage and use by the end-user of the product. NOTE 1. Some containers may need to withstand multiple opening and re-fitting of the lid, depending on the envisaged end-use. NOTE 2. Performance might be reduced from original levels. NOTE 3. Manual opening and re-fitting operations shoul
36、d be tested by non-professional personnel. 6.3 Lid retention When tested in accordance with annex J, 95 % of containers tested shall not incur sustained or significant leakage through lid displacement or failure of the container body in both the drop and topple tests. 6.4 Stacking When tested in acc
37、ordance with annex K, containers shall exhibit no significant physical deformation in both the conventional stack test and the offset stack test. NOTE. Plastics containers will creep if placed under load for some time. A practical test, carried out under representative conditions of storage and dist
38、ribution, loading and temperature, should be agreed between customer and supplier. 6.5 Handles 6.5.1 Handle strength After testing in accordance with annex L, handles shall be unbroken, shall still be secure on both sides and shall still be capable of holding the container plus the mass of the conte
39、nts, and the container shall still conform to 6.1. NOTE. Some distortion of the components may result from the strains of the test. 6.5.2 Handle securing Handles and handle securing units moulded from plastics materials shall not be tested until at least 24 h after moulding. 6.5.3 UV resistance Wher
40、e moulded from plastics material, the handle and/or handle securing units fitted to the container shall still conform to 6.5.1 after exposure to UV light in accordance with annex M.

43、chaser. The volumes and overall dimensions of table A.1 are recommended because they are common sizes which are compatible with existing filling and packaging machinery, and with existing facilities for storage, handling and distribution. Annex B (normative) Methods for the determination of gross li
44、dded capacity B.1 General The gross lidded capacity of the container shall be determined as described in either B.2 or B.3. B.2 Method A B.2.1 Drill two holes 3 mm to 6 mm in diameter in the bottom of the container, about 7 mm apart and each as close as possible to the circumference of the base. Rem
45、ove the burrs. B.2.2 Fit the lid ensuring that it is fully secured. B.2.3 Determine the mass of the closed, empty container (m1), in grams, as accurately as possible (see table B.1 for the required precision of the weighing apparatus). B.2.4 Fill the container with water at (185) C through one of th
46、e holes using a narrow jet, with the container inclined at an angle to the vertical so that the holes are as high as possible. B.2.5 When water runs out of the second hole, close the holes with the finger, shake the container gently and then complete the filling with the container inclined at an ang
47、le as before. Withdraw the container vertically. B.2.6 Carefully remove all surplus water from the outside of the container. B.2.7 Determine the mass of the filled container (m2), in grams, using weighing apparatus of the appropriate precision given in table B.1. B.2.8 Determine the numerical value
48、of the gross lidded capacity of the container in millilitres by calculating the difference between the masses (m22 m1), in grams.
