TS 1118-3 EN ISO 90-3

TS 1118-3 EN ISO 90-3 is a standard focused on round aerosol cans, bringing together definitions and the determination of dimensions and capacities for this specific type of thin-walled metal container. In practical terms, it gives the sector a common technical language for describing geometry and volumetric characteristics, so that design, measurement and specification can be handled consistently.

Why dimensions and capacity are treated together

For aerosol cans, diameter, aperture and construction are not separate in practice: they affect filling, compatibility, handling and the overall behaviour of the container. The standard’s scope covers the identification of these features for round cans and the determination of capacity values. In general technical terms, capacity may be described in different ways, and the distinction between gross capacity and wipe-filling capacity helps separate different reference volumes used in packaging engineering.

Measurement, tolerances and designation

The standard also specifies methods for determining diameters and capacities and includes capacity tolerances, which is important for consistent specification and quality control across manufacture and supply. It additionally recommends an international designation, supporting clearer communication in cross-border trade and technical documentation. As with any document of this type, the emphasis is on the defined round aerosol can context rather than on all possible metal container forms.

• Defines terminology for round aerosol cans.
• Addresses diameters, apertures, constructions, shapes and capacities.
• Includes methods for determining diameter and capacity values.
• Gives capacity tolerances and recommends an international designation.
