8、BSI 11-1999 National foreword This Part of BS 6966 has been prepared under the direction of the Packaging and Freight Containers Standards Committee. It is identical with ISO 90-3:1986 “Light gauge metal containers Definitions and determination methods for dimensions and capacities Part 3: Aerosol c
9、ans”, published by the International Organization for Standardization (ISO). Other Parts in the series are as follows: In 1992 the European Committee for Standardization (CEN) accepted ISO 90-3:1986 as European Standard EN 20090-3:1992. As a consequence of implementing the European Standard this Bri
10、tish Standard is renumbered as BS EN 20090-3 and any reference to BS 6966-3 should be read as a reference to BS EN 20090-3. Part 1: Glossary of terms for open-top cans and methods for determination of dimensions and capacities; Part 2: Glossary of terms for general use containers and methods for det
11、ermination of dimensions and capacities; Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attenti
12、on is drawn especially to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Wherever the words “ISO 90” or “part of ISO 90” appear, referring to this standard, they should be read as “BS
13、6966” or “Part of BS 6966”, respectively. 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. Compliance with a British Standard does not of itself confer immunity from legal obligations.

27、ns and capacities, and tolerances and designations of light gauge metal containers. This part of ISO 90 covers aerosol cans as defined in 2.1. The two other parts are Part 1: Open-top cans. Part 2: General use containers. NOTEAn “open-top can” is a can one end of which is double-seamed after filling
28、. A “general use container” is a container which is sealed after filling with a closure that need not be double-seamed. 1 Scope and field of application This part of ISO 90 defines cans and aerosol cans, diameters, aperture, constructions, shapes and capacities. It specifies methods for determining
29、diameters, and package and brimful capacities. It also gives tolerances on capacity and recommends an international designation. 2 Definitions For the purposes of ISO 90 and related International Standards, the following definitions apply. 2.1 Cans 2.1.1 can rigid container made of steel-based plate
30、, with a maximum nominal material thickness of 0,49 mm, or of aluminium and its alloys 2.1.2 aerosol can non-refillable can intended to contain a product which is dispensed by pre-stored pressure in a controlled manner through a valve 2.2 Diameters 2.2.1 internal diameter (for steel-based plate cans
31、) see Figure 1 a) 2.2.2 external diameter (for aluminium cans) see Figure 1 b) Figure 1 Licensed Copy: sheffieldun sheffieldun, na, Fri Nov 03 08:04:45 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 20090-3:1992 4 BSI 11-1999 2.3 aperture circular opening designed to be sealed by a valve component. T
32、he valve is mounted either in an internally fitting cup or on an externally fitting ferrule 2.4 Constructions 2.4.1 three-piece can (built-up can) can made from three main components: body, top end and bottom end Figure 2 Licensed Copy: sheffieldun sheffieldun, na, Fri Nov 03 08:04:45 GMT+00:00 2006

37、e, determined in accordance with 4.2 2.6.2 brimful capacity, C2 (in millilitres) the total capacity of a can without a closure, determined in accordance with 4.3 3 Determination of dimensions 3.1 Measurement of diameters 3.1.1 Measure the internal body diameter using a plug gauge or derive it from t
38、he external diameter. 3.1.2 Measure the external body diameter using a vernier caliper. 3.1.3 Measure the necked-in diameter using a plug gauge applied to the internal diameter of the extremity to which the end is to be fixed. 3.2 Nominal diameters When a series of standard body diameters (or necked
39、-in diameters) has been agreed, the tolerances define the limits of acceptable deviation resulting from variations in can design and manufacture. Determine the nominal diameters by rounding the standard body or necked-in diameters to the nearest whole millimetre (if the first decimal is 5 or above,
40、round up; in all other cases, round down).

41、e following data: for all aerosol cans: diameter Di or De (see 2.2) in addition, for necked-in cans: diameter(s) DN1 and/or DN2 (see 2.5.2) 4 Determination of capacities 4.1 General The methods for determining capacity all rely on obtaining the mass of water in the can. For cans with a capacity equa
42、l to or greater than 400 ml, a correction factor (see 4.1.1) can be applied, but only if a very precise determination of capacity is necessary. 4.1.1 Temperature-dependent correction factor Table 1 Correction factors 4.1.2 Accuracy of the balances The scales used for weighing the cans shall be at le
43、ast as accurate as specified in Table 2. Table 2 Balance accuracy 4.2 Determination of package capacity, C1 4.2.1 Determine the mass of the empty can, together with the valve, valve cup and dip tube, mv1, in grams, as accurately as possible (see 4.1.2). 4.2.2 If necessary, measure the temperature of
44、 the water to be used (see 4.1.1). 4.2.3 Fill the can completely with water. 4.2.4 Insert the separated dip tube loosely (the length should correspond to the can height). 4.2.5 Press the valve cup with fully assembled valve into the aperture of the can. 4.2.6 Remove any surplus water from the outsid
45、e of the can. 4.2.7 Determine the mass of the filled can, mv2, in grams, as accurately as possible (see 4.1.2). 4.2.8 The difference between the weighings (mv2 mv1), if necessary multiplied by the relevant correction factor (see 4.1.1), represents the package capacity, C1, of the can, in millilitres

49、perture, and complete filling through the holes. The can should be shaken, if necessary, during the filling process to ensure the release of any trapped air. 4.3.6 Remove any surplus water from the outside of the can. 4.3.7 Determine the mass of the filled can together with the disc, md2, in grams, as accurately as possible (see 4.1.2). 4.3.8 The difference between the weighings, (md2 md1), if necessary multiplied by the relevant correction factor (see 4.1.1), represents the brimful capacity
