11、ional standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. Interna
12、tional organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the r
13、ules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the p
14、ossibility that some of the elements of this part of ISO 90 may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. International Standard ISO 90-3 was prepared by Technical Committee ISO/TC 52, Light gauge metal containers, Subcommittee
15、SC 6, Aerosol containers. This second edition cancels and replaces the first edition (ISO 90-3:1986) which has been technically revised.

20、1 Light gauge metal containers Definitions and determination of dimensions and capacities Part 3: Aerosol cans 1Scope This part of ISO 90 defines the diameters, apertures, constructions, shapes and capacities of round, aerosol cans. It specifies methods for determining diameters, gross lidded and br
21、imful capacities. It also gives tolerances on capacity and recommends an international designation. NOTEA list of standards dealing with materials used for aerosol cans is given in the Bibliography. 2Terms and definitions For the purposes of this part of ISO 90, the following terms and definitions a

The figures given in this clause illustrate the terminology. 2.1 aerosol can rigid can made of light gauge metal with a maximum nominal material thickness of 0,49 mm; non-refillable can intended to contain a product which is dispensed by pre-stored pressure in a controlled manner through a val

For cans wit
42、h a capacity equal to or greater than 400 ml, a correction factor (see 4.1.1) may be applied, but only if a very precise determination of capacity is necessary. 4.1.1Temperature-dependent correction factor Table 1 gives the values of correction factors for the determination of capacity with respect
43、to the temperature of water.
