The work of preparing International Standards is normally carried out
20、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. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO coll
21、aborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 3. Draft International Standards adopted by the technical committees ar
22、e 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 possibility that some of the elements of this part of ISO 90 may be the subject of patent rights. ISO shall not be
23、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 SC 6, Aerosol containers. This second edition cancels and replaces the first edition (ISO 90-3:1986) which has bee
24、n technically revised. ISO 90 consists of the following parts, under the general title Light gauge metal containers Definitions and determination of dimensions and capacities: Part 1: Open-top cans Part 2: General use containers Part 3: Aerosol cans NOTE An “open-top can“ is a can one end of which i
25、s double-seamed after filling. A “general use container“ is a container which is sealed after filling with a closure that need not be double-seamed. Annex A of this International Standard is for information only. ENISO903:2001 v Introduction ISO 90 consists of three parts which group definitions, me
26、thods of determination of dimensions and capacities, as well as tolerances and designations of rigid containers made of metal with a maximum nominal material thickness of 0,49 mm.

It specifies methods for determining diameters, gross lidded and brimful capacities. It a
28、lso gives tolerances on capacity and recommends an international designation. NOTE A list of standards dealing with materials used for aerosol cans is given in the Bibliography. 2 Terms and definitions For the purposes of this part of ISO 90, the following terms and definitions apply. The figures gi

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

46、the disc, m d1 , in grams, as accurately as possible (see 4.1.2). 4.2.3 If necessary, measure the temperature of the water to be used (see 4.1.1). ENISO903:20019ISO -093:(0002)E 01 ISO 0002 All rights rsedevre 4.2.4 Fill the can with water, avoiding air bubbles. 4.2.5 Close the can with the disc, th
47、e hole(s) in the disc being as close as possible to the edge of the aperture, 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. 4.2.6 Remove any surplus water from the outside of the can. 4.2.7 Determi
48、ne the mass of the filled can together with the disc, m d2 , in grams, as accurately as possible (see 4.1.2). 4.2.8 The difference between the weighings, (m d2 m d1 ), if necessary multiplied by the relevant correction factor (see 4.1.1), represents the brimful capacity, C 2 , in millilitres, of the can. 5 Tolerances on capa
