Overview
ISO/TR 11762:1992 is a Technical Report from ISO/TC 52 that classifies round open-top, light-gauge metal cans for liquid products with added gas by construction type. Rather than establishing new mandatory specifications, this type‑3 Technical Report provides informational data - notably a list of nominal filling volumes and opening diameters organized by can construction: straight-sided cans, single necked‑in cans, and multiple necked‑in cans. Annex A supplies a reference list of sizes formerly standardized in ISO 3004-3 that no longer meet criteria for inclusion in ISO 10654.
Key Topics
- Classification by construction type: The report separates can sizes for straight-sided, single necked‑in and multiple necked‑in constructions, helping users map size options to form factor.
- Nominal filling volumes: A compiled list of nominal volumes is provided for each construction type (the report cross-references ISO 10654, which specifies nominal filling volumes).
- Opening diameters: Opening sizes are listed in millimetres; the publication includes representative diameters such as 50, 53, 57, 63 and 65 mm.
- Legacy size references: Annex A lists can sizes that were standardized under the former ISO 3004-3 but are now considered non-conforming for ISO 10654 - examples shown in the report include numeric size entries like 275, 296, 330.
- Informational status: As a Technical Report (type 3), ISO/TR 11762:1992 documents the state of the art and is intended as background information rather than a prescriptive standard.
Applications
ISO/TR 11762:1992 is useful for:
- Packaging engineers and product designers selecting an appropriate can construction and nominal volume for carbonated or gas‑added liquid products.
- Can manufacturers and tooling designers aligning manufacturing options (opening diameter, necking approach) with commonly referenced size classifications.
- Beverage producers evaluating packaging formats for production line compatibility and product presentation.
- Procurement and specification writers who need an authoritative reference to common can sizes by construction type.
- Standards bodies and technical committees reviewing historical sizes and harmonizing current standards (see Annex A).
Practical benefits include faster format selection during concept development, clearer communication between suppliers and manufacturers, and a historical reference to legacy can sizes.
