BS EN ISO 20743:2021

Determination of antibacterial activity of textile products

The ISO 20743:2021 standard outlines a test method to determine the antibacterial activity of textile products incorporating an antibacterial finish to prevent or mitigate the growth of bacteria. ISO 20743:2021 applies to the testing of cloth, material for clothing, bedding, home furnishings etc., and nonwovens.

Test Description

  • Bacteria (Staphylococcus aureus or Klebsiella pneumoniae) are inoculated onto treated (test) and untreated (control) fabric. Other bacteria can be requested.
  • The samples are incubated for a set duration (typically 18 to 24 hours), after which viable bacteria are extracted from the test and control fabrics and enumerated.
  • The antibacterial activity of the textile product is calculated according to the criteria in the standard.
