11、rection of the Packaging and Freight Containers Standards Policy Committee. It is a revision of BS 1262:1970 which is withdrawn. The revision limits the scope to round lever lid cans, specifically developed for paint and allied products, although used in considerable quantities for adhesives and a v
12、ariety of other products, including powders. The range of nominal capacities is restricted to those agreed by the Paintmakers Association of Great Britain Ltd. and the Metal Packaging Manufacturers Association at the time of metrication and the capacities specified are included in Directive 80/232/E
13、EC “Ranges of nominal quantities and nominal capacities of pre-packaged products”. Additional requirements and methods of test have been incorporated, relating to handle strength and lid security. General guidance on these and other types of cans used for paint products is given in BS 1133-10. It is
14、 also anticipated that new British Standard specifications will be developed for rectangular and cone top cans used for paint products. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application.
15、 Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 12, an inside back cover and a back cover. This standard has been updated (see copyright date) and
16、may have had amendments incorporated. This will be indicated in the amendment table on the inside front cover.

17、nsions and constructional requirements for a range of round lever lid tinplate containers (in general referred to as cans), with nominal capacities between 250 mL (millilitres) and 5 L (litres), intended primarily for paints and other products of the paint industry. Performance requirements and rela
18、ted methods of test are included covering freedom from leaks, handle strength and lid security. A method for the determination of gross lidded capacity is also included as Appendix A. NOTEThe titles of the publications referred to in this standard are listed on the inside back cover. 2 Definitions F
19、or the purposes of this British Standard the definitions given in BS 3130-4 apply. 3 Designation 3.1 The cans in the specified range (see Table 1) shall be designated as follows: 250 ml 500 ml 1 litre 2.5 litre 5 litre 3.2 The nominal volumes for the specified range shall be as given in Table 1. NOT
20、EThe figures for nominal diameter and height are intended for descriptive purposes only. Table 1 Nominal dimensions of the specified range 4 Materials, design and manufacture 4.1 Materials 4.1.1 Bodies, bottom ends, closure rings and lids shall be manufactured from tinplate with nominal thickness as
21、 specified in Table 2. NOTEHandles may be of metal or plastics material. 4.1.2 End lining compound and, where used, body seam cement shall be compatible with the intended contents, appropriate to the filling operation and suitable for the intended use (see Appendix B). 4.1.3 Internal lacquer, where
22、used, shall be compatible with the intended contents (see Appendix B). 4.2 Design 4.2.1 The gross lidded capacities shall be as specified in Table 2 when determined in accordance with the method given in Appendix A. 4.2.2 The dimensions of the cans shall be as specified in Table 2 and shown in Figur
23、e 1 and Figure 2. Dimensions relating to handle position, when fitted to the 2.5 litre and 5 litre cans, shall be as specified in Table 2 and shown in Figure 2. 4.3 Construction 4.3.1 The body shall be made from one piece of tinplate formed into a cylinder. The seam shall be either lap welded, hooke
24、d and soldered or hooked and cemented. 4.3.2 The bottom end and top closure ring shall be secured by double seaming. The double seam shall incorporate a gasket material in the form of a lining compound to ensure a leakproof joint. 4.3.3 If provided, registration features for radial positioning of th
25、e can shall be in the form of top and/or bottom indents at the body seam. The indents shall conform to the dimensions shown in Figure 1 and Figure 2 (for hooked body seam cans and welded body seam cans respectively) and shall be positioned as in D and E of Table 2.

41、the can shall be determined as described in either A.2 or A.3. A.2 Method A A.2.1 Drill two holes 3 mm to 6 mm in diameter in the bottom of the can about 7 mm apart and each as close as possible to the circumference of the base. Remove the burrs. A.2.2 Fit the lever lid ensuring that it is driven fu
42、lly home. A.2.3 Determine the mass of the closed empty can “m1” in grams as accurately as possible (see Table 4 for the required precision of the weighing apparatus). A.2.4 Fill the can with water at room temperature (15 C to 20 C) through one of the holes using a narrow jet, with the can inclined a
43、t an angle to the vertical so that the holes are as high as possible. A.2.5 When water runs out of the second hole, close the holes with the fingers, shake the can gently and then complete the filling with the can inclined at an angle as before. Withdraw the can vertically. A.2.6 Carefully remove al
44、l surplus water from the outside of the can. A.2.7 Determine the mass of the filled can “m2” in grams using weighing apparatus of the appropriate precision given in Table 4. A.2.8 The difference between the weighings (m2 m1) represents the gross lidded capacity of the can in millilitres. Table 4 Pre
45、cision of weighing apparatus A.3 Method B A.3.1 Drill two holes 3 mm to 6 mm in diameter in the bottom of the can, diametrically opposite each other and each as close as possible to the circumference of the base. Remove the burrs. A.3.2 Fit the lever lid ensuring that it is driven fully home. A.3.3
46、Determine the mass of the closed empty can “m1” in grams as accurately as possible (see Table 4 for the required precision of the weighing apparatus). A.3.4 Immerse the can, bottom upwards, in a bucket or tank of clean water at room temperature (15 C to 20 C). A.3.5 Tilt slightly to dispel any resid
47、ual pocket of air. Withdraw the can vertically. A.3.6 Carefully remove all surplus water from the outside of the can. A.3.7 Determine the mass of the filled can “m2” in grams using weighing apparatus of the appropriate precision given in Table 4. A.3.8 The difference between the weighings (m2 m1) re
48、presents the gross lidded capacity of the can in millilitres. Appendix B Fitness for use The correct container specification needs to be established between purchaser and supplier, based where necessary on data from specialist test laboratories, to secure compatibility between container and product.
49、 The specification should include reference to: a) end lining compound; b) body seam cement; c) internal lacquer; d) external coating material; e) type of handle securing unit and handle; f) adequacy of seal for the product. The suitability of cans complying with this standard for use with a particular product should also take account of any regulations governing the use and transport of that product.
