Quick answer: gown levels describe barrier performance under specific lab tests, not the settings where a gown may be worn. The AAMI level system grades gowns 1 to 4 by increasing resistance to penetration and pressure, and CSA requirements address the same performance question from the Canadian side. Buyers should specify level plus test method plus intended task, not level alone. Our SMMS 40 gsm Level 2 isolation gowns are specified for routine clinical contact.
What do the four AAMI levels actually measure?
Each level corresponds to a set of bench tests — impact penetration for the lower levels, hydrostatic resistance for the higher ones — run on the gown fabric and, at higher levels, on critical seam areas. The result is a barrier rating under laboratory conditions. It is not a statement about how long a gown resists a specific fluid in a specific room, which is why the intended task has to be part of the specification.
| Level | Barrier expectation | Typical task |
|---|---|---|
| Level 1 | Minimal fluid contact | Basic care, non-fluid tasks |
| Level 2 | Low to moderate fluid | Blood draws, routine clinic contact |
| Level 3 | Moderate fluid, longer exposure | Procedures with splashing |
| Level 4 | Highest barrier, including seams | High-fluid, long-duration work |
The level is a starting point; the task decides whether it is enough.
How does CSA fit into a Canadian buying decision?
CSA standards cover medical textiles and gown performance in Canada, and they are referenced alongside the AAMI system rather than replacing it. In practice a Canadian buyer should ask two separate questions: does the product meet the barrier level required for the task, and does the manufacturer hold current test reports to the method being quoted? A supplier that answers only the first has not answered the second.
What else changes between gowns at the same level?
Fabric weight, seam construction, tie placement, cuff style and length. Two Level 2 gowns can feel entirely different: a 40 gsm SMMS gown drapes and breathes differently from a lighter spunbond. Seam construction matters at the higher levels, because a fabric that passes a bench test can still fail at an unsealed seam.
How should a clinic specify a gown order?
Write five elements on the purchase order: level, fabric and weight, size range, cuff and tie configuration, and the test report reference. Then add the intended task, so the specification survives a change of supplier. Clinics that specify only “Level 2 gowns” tend to receive products that meet the level and fit the task poorly.
Where does gown ordering sit with other PPE?
Gowns, masks and gloves are consumed at the same rate and are usually ordered together to share freight. Multi-site groups can review wholesale and multi-site ordering, and the B2B wholesale collection lists the PPE lines held for institutional buyers. A printable PPE usage and receiving log and the log generator keep lot numbers with the stock record. Reselling? become a distributor.

Frequently Asked Questions
What is the difference between AAMI Level 1 and Level 4 gowns?
Barrier performance under bench testing increases from Level 1 to Level 4, with Level 4 also covering critical seam areas. The task, not the number, decides what is needed.
Do Canadian clinics need CSA-certified gowns?
Gown performance in Canada is described through CSA standards alongside the AAMI level system. Ask the supplier for current test reports to the method being quoted.
Is a heavier gown always better?
No. Weight affects comfort and breathability; barrier performance comes from the fabric and seam construction tested to the relevant method.
What should be on a gown purchase order?
Level, fabric and weight, size range, cuff and tie configuration, test report reference, and the intended clinical task.
