Physical Testing of Dressings

Test Methods for Primary Wound Dressings (European Standard EN 13726-1 2002)

Part 1  Aspects of absorbency


  Free swell absorbency     

  Fluid handling capacity

  Fluid affinity of amorphous hydrogel dressings

  Gelling characteristics

  Dispersion characteristics

  Dispersion/solubility of hydrogel dressings  

Part 2  Moisture Vapour Transmission Rate of permeable film dressings


  MVTR of a wound dressing when in contact with water vapour

  MVTR of a wound dressing when in contact with liquid

Part 3  Waterproofness
