What each consumable proves
ISO 11140-1 sorts chemical indicators into six types. The higher the type, the more of the cycle it responds to.
| Item | ISO 11140-1 type | What it shows | What it does not show |
|---|---|---|---|
| Autoclave tape | Type 1 (process) | The item was exposed to a cycle | That the contents are sterile |
| Printed pouch indicator | Type 1 (process) | The pouch went through a cycle | That steam reached the instrument |
| Bowie-Dick test sheet or pack | Type 2 (specific test) | Air removal and steam penetration in a vacuum unit | Anything about patient loads |
| Multi-variable indicator | Type 4 | Two or more critical variables were reached | Full cycle performance |
| Integrator strip | Type 5 | All critical variables, set against biological performance | It does not replace spore tests |
| Emulating indicator | Type 6 | The parameters of a specific stated cycle were met | Performance of other cycles |
Choosing sterilisation pouches
Self-seal or heat-seal
Self-seal pouches have an adhesive strip and need no equipment. Heat-seal pouches or reels need a sealer but let you cut any length.
Made for steam
Use pouches specified for steam sterilisation, ideally with a printed steam indicator.
Right size
The instrument should fit with space around it and without stretching the seal. Sharp tips can pierce the pouch — use tip protectors where needed.
Packing, labelling and storage
- Clean and dry instruments before pouching; open hinged instruments.
- Do not overfill — steam must reach every surface.
- Write the date, cycle number and contents outside the sealed area.
- Let pouches dry fully in the autoclave; reprocess any that come out wet or torn.
- Store in closed, clean, dry cupboards off the floor and away from sinks.
