Overview - ISO/TR 11761:1992 (Light-gauge metal containers, round open-top cans)
ISO/TR 11761:1992 is a Technical Report that classifies round open-top, light-gauge metal containers by construction type and gives a consolidated list of nominal gross lidded capacities and nominal diameters for those can types. As an informative (Type 3) report, it complements ISO 10653 by providing a classification and reference sizing for common can constructions rather than prescriptive manufacturing rules.
Key topics and technical scope
- Scope and purpose: Lists standard nominal capacities (ml, L) and corresponding nominal diameters (mm) for round open-top cans, organized by construction type.
- Construction types covered:
- 3-piece cans, straight walls
- 3-piece cans with simple reduction (necked)
- 3-piece conical cans (truncated)
- 2-piece cans, straight walls
- 2-piece cans with shoulder
- 2-piece conical cans
- 2-piece conical cans with shoulder
- Sizing tables: Detailed tables show nominal gross capacities and the recommended nominal diameters for each construction type.
- Annex A (informative): Reference list of can formats formerly standardized in ISO 3004 that no longer meet criteria for inclusion in ISO 10653.
- Notes and calculation: The report notes the method for calculating nominal diameter as under study in the original text; it therefore serves as a reference classification rather than a final dimensional method specification.
- Context and cross-references: The report refers to ISO 90-1 (definitions and dimensional methods for seamed cans), ISO 1361 (inner diameters), and ISO 10653 (cans defined by nominal capacity).
Practical applications and users
- Who uses it:
- Packaging engineers and designers specifying round open-top cans
- Can and lid manufacturers (tooling and line setup)
- Quality, procurement, and standards teams verifying part compatibility
- Product formulators and food processors selecting standardized pack sizes
- Regulatory and conformity assessors referencing historical size classes
- How it’s used:
- Selecting appropriate nominal capacities and diameters for production and supply-chain compatibility
- Aligning can construction type (2-piece vs 3-piece, conical vs straight) with product, filling equipment, and closure systems
- Referencing legacy can sizes (Annex A) when evaluating replacement or obsolescence of formats formerly in ISO 3004
