One Symbol Set, So a Label Speaks Every Language at Once.
ISO 15223-1 strategy for medical device labelling — the harmonised symbols that carry required information without translation, applied to the current edition and kept in step with your labelling system.
The Symbols Do the Work Words Would Otherwise Repeat in Every Language.
ISO 15223-1 standardises the symbols that convey the information a label must carry — who made it, when it expires, whether it’s sterile, and more. Use the current edition’s symbols correctly and one label serves many markets.
Manufacturer
The legal manufacturer of the device.
Use-By Date
The date after which the device should not be used.
Batch / Lot Code
The manufacturing batch or lot identifier.
Catalogue Number
The manufacturer’s catalogue reference.
Sterile
The device has been sterilised (with its method).
Do Not Reuse
A single-use device — not to be reprocessed.
Consult IFU
Refer to the instructions for use before using.
Caution
Consult accompanying documents for warnings.
Editions matter. ISO 15223-1 is revised, symbols are added and refined, and a symbol drawn to a superseded edition is a recurring Notified Body finding — which is why the standard is a labelling-system decision, not a clip-art library.
A Symbol From the Wrong Edition Is a Finding. Get the Set Right, System-Wide.
ISO 15223-1 looks minor next to the clinical and safety standards — and it generates a steady stream of Notified Body findings anyway. The failure mode is mundane: a symbol drawn to a superseded edition, a symbol used where the standard specifies text, or a symbol whose meaning drifts from what the label intends. Each is small; together they read as a labelling system that isn’t controlled.
The standard also under-girds the rest of your labelling: it defines the vocabulary that ISO 20417 then requires you to supply, and it carries the UDI and other data a modern label bears. Get the symbol library right once, at the system level, and dozens of labels inherit it.

The right edition, applied consistently across every label, is what turns a symbol set into compliance.
Six Disciplines That Keep Symbols Compliant.
From the symbol library to the change control that keeps every label in step with the current edition.
Symbol Library & Edition Control
A controlled symbol library built to the current ISO 15223-1 edition — the single source every label draws from, so a superseded symbol can’t slip through.
Symbol-vs-Text Determination
Where a symbol is permitted and where the standard still requires accompanying text — the judgment that keeps a label both compliant and readable.
Label Layout & Legibility
Symbols sized and placed for legibility on the package and device — and coordinated with the UDI carrier and other required marks.
Multi-Market Harmonisation
One symbol set that serves the markets you sell in — reconciling FDA, EU, and other expectations into a single labelling approach.
Labelling Change Control
Symbol and edition changes wired into your labelling change control — so a standard revision updates every affected label, not just the next one.
Pre-Audit Symbol Review
The full label set reviewed against the current edition before a Notified Body does it — the check that turns a recurring finding into a non-event.

Symbols, UDI, and manufacturer information share the same label — designed together or they collide.
A Modern Label Carries Symbols, a UDI, and Manufacturer Information — All at Once.
The label is no longer just print; it’s a data surface where ISO 15223-1 symbols, the UDI carrier, and the information ISO 20417 requires all have to coexist legibly. Treat any one of them in isolation and they collide — the symbol set that ignores the UDI, the layout that crowds out the required text.
We design the label as one coherent surface across all three standards, and connect it to labelling and change control — so the symbols, the identifier, and the manufacturer information stay consistent every time the catalogue moves.
Six Failure Modes We Are Brought In to Prevent.
Each is small on its own — and collectively they read as an uncontrolled labelling system.

Superseded-edition symbols
A symbol drawn to an old edition still on current labels — the recurring Notified Body finding that signals an uncontrolled library.
Symbol where text is required
A symbol used where the standard still mandates accompanying text — compliant-looking, and non-compliant.
The uncontrolled clip-art library
Symbols pulled ad hoc into artwork with no single controlled source — so every designer’s label drifts a little differently.
Symbols that crowd the UDI
A layout that treats symbols in isolation — and can’t fit the UDI carrier and required text legibly.
A revision that updated one label
A standard edition change applied to the next new label but not the existing portfolio — a mixed estate of editions.
Meaning drift
A symbol used loosely, its on-label meaning drifting from the standard’s definition — a subtle error a careful reviewer catches.
Labelling Symbol Discipline, Run at the System Level.
Our labelling leads have built controlled symbol libraries, harmonised across markets, and kept portfolios current through edition changes.

“ISO 15223-1 is small until it isn’t. Control the symbol library at the system level and dozens of labels stay compliant; leave it to artwork and every one drifts.”
The discipline we bring to device labelling.
Is Your Whole Portfolio on the Current Symbol Edition? Prove It Before a Notified Body Asks.
A senior labelling lead can build a controlled symbol library, harmonise it across your markets, and bring the portfolio onto the current edition — system-wide, not label by label.
Senior-led. Embedded in your team. No junior hand-offs.
