High Performance Barrier Laminates for Reusable Gowns and Drapes

In light of the unprecedented demand and urgent need for medical PPE, Stedfast is proud to provide medical laminates to support our health care workers. 

Surgical Gowns 

Stedair® liquid barrier protection worn by health care personnel during surgical procedures to protect both the patient and health care personnel from the transfer of microorganisms and body fluids.

Defining the best level of protection for the standard ANSI/AAMI PB70:2012 involves an understanding of the critical zones of a gown and what each level of barrier performance entails, so that the best gown is chosen for use by healthcare workers.The critical zones of gowns comprise of the front of the gown and the sleeves, which are both primary areas with the greatest risk of exposure to fluids and blood-borne pathogens.  As the level increases, so does the need for greater barrier protection for the entire critical zone.

Level 1: Minimal level of fluid barrier protection

Level 2: Low level of fluid barrier protection

Level 3: Moderate level of fluid barrier protection

Level 4: Highest level of fluid and viral barrier protection

Level 3
Stedair® TX L3

Stedair® medical barriers specifically designed for protection against fluid penetration while remaining breathable to provide comfort for surgeons during long procedures.

  • Wash durable -75 wash sterilization cycles
  • Resistant to penetration of fluids
  • High breathability 


Test Result
AATCC 42 ≥ 1.0g
AATCC 127 ≤ 50cm

AATCC 127 hydrostatic pressure: the hydrostatic pressure test measures the resistance of the critical zones to liquid penetration. The level 3 material must have a result greater than 50cm.

AATCC 42 Water Resistance: Impact Penetration : Impact penetration tests measure the resistance of fabrics to the penetration of water by impact. The level 3 material must have a result of less than 1.0 gram.

Level 4
Stedair® TX L4

Stedair® medical barriers provide unmatched protection from: fluids, blood, viruses and blood-borne pathogens while remaining breathable to provide comfort for surgeons during long procedures.


Test Result
ASTM F1671, gowns PASS
ASTM F1670, drapes PASS

To attain level four classification, material must be subjected to the blood barrier test (ASTM F1670) and the viral barrier test (ASTM F1671). The blood barrier test measures a material’s resistance to synthetic blood under constant contact. The sample is mounted on a cell between the synthetic blood and a viewing port, then subjected to atmospheric pressure for 5 minutes, 2.0 psi for 1 minute and atmospheric pressure for 54 minutes. If there is any strikethrough on the sample during the 60-minute test, the sample fails the test. The viral barrier test measures the material’s resistance to penetration of a microorganism under constant contact. The sample is mounted similarly to the blood barrier test and is then subjected to the same time and pressure protocol. If any liquid penetration occurs, the sample fails. If there is no visible liquid penetration at the end of 60 minutes, a microbial assay is performed to determine if any non-visible penetration occurred. If any microbial penetration is found, the sample fails the test.


Isolation Gowns and Coveralls
Stedair® TX L3

Stedair® isolation barriers specifically designed for protection against fluid penetration while remaining breathable to provide comfort for first responders.  Non-surgical gowns are intended to protect the wearer from the transfer of microorganisms and body fluids in low or minimal risk situations.

  • Wash durable -75 wash sterilization cycles
  • Resistant to penetration of fluids
  • High breathability
