NONSTERILE

Non-sterile (NON STERILE triangle)

The standard’s wording, as the sources below reproduce it:

“Indicates a medical device that has not been subjected to a sterilization process.”

ISO 15223-1:2021, 5.2.7 · ISO 7000-2609

What it means for you

The device was not sterilised. That is normal for many products that only touch intact skin — tapes, bandages, thermometers, examination gloves — but it matters if you were about to use it on an open wound or in a sterile procedure.

Whether a device is right for you is a question for your pharmacist, nurse or doctor.

What it looks like
A triangle, point up, with the words NON STERILE inside.
Where you see it
Examination gloves, elastic bandages, tapes, splints, instruments that are meant to be cleaned and sterilised by the user before first use.
Other names
NON STERILE; not sterile

What it does not tell you

It does not say the item is dirty or unsafe, and it does not tell you how to sterilise it; if the item must be sterilised before use, the instructions say how.

Often confused with

Indicates a medical device that has been subjected to a sterilization process.
