TS 1118-1 EN 20090-1

TS 1118-1 EN 20090-1 is the first part of a standard dealing with light-gauge metal open-top cans, focusing on how their dimensions, shapes, construction features and capacities are defined. It covers the classification of these cans and addresses methods for determining gross capacity and cross-sections, together with recommendations for capacity tolerances and international abbreviated designations.

Core technical ideas behind open-top cans

In metal packaging, geometry is tightly linked to performance. For open-top cans, diameter, height, body profile, base formation and rim design influence filling, closing, stacking and transport behaviour. Gross capacity is a key concept for describing the internal volume of the container, while cross-section is used to characterise shape and support consistent manufacturing and specification. These concepts help distinguish one can form from another in a technically meaningful way.

What this standard covers

• Definitions of open-top can types and shape categories.
• Methods for determining cross-sections and capacities.
• Guidance related to capacity tolerances.
• Recommendations for international short designations.
• A common technical vocabulary for thin-gauge metal containers.

This record is a withdrawn standard, but its subject remains relevant in metal packaging documentation and product specification. It is useful when design teams, manufacturers and technical writers need a consistent way to describe can forms and compare sizes without ambiguity.
