ISO 18184 Textiles – Determination of Antiviral Activity of Textile Products

Antiviral textile products are textiles capable of reducing the number of infective virus particles that contact the surface of the textile.  This test provides a quantitative method to assess the antiviral performance of such products.

Textile products suitable for this test include woven and knitted fabrics, fibres, yarns, braids etc.  Very thick or absorbent products (such as carpets which cannot be removed from the backing) may not be suitable for testing by this method.

Principle of the Test

A small amount of virus is placed on the treated and untreated fabric and allowed to remain for the contact time.  After the contact time, the virus is washed off and added to the specific host cells.  The cells are incubated for several days to allow any remaining virus to be quantified.  The amount of virus surviving on the test and control fabric is calculated.  This is the logarithmic (log) reduction and is also expressed as a percentage reduction on the test report.

If you would like to determine the antiviral activity of your textile products, you can book a test by following the steps below. Please enter all of the information required and read any guidance notes next to each box as they contain useful information, which may affect your results.

  1. Enter your company information and contact details. We will send the report to the email address supplied on this page
  2. Next, enter your sample details, one test per fabric to be tested. The control fabric (if supplied) is included in the cost.  If you do not supply your own reference control, we will use our own plain cotton as a control
  3. Select the date you would like to receive your report from the options available
  4. Review and confirm all details supplied are correct
  5. Send us your samples within seven days of submitting your order
  6. We will then perform the test and submit your technical report on the agreed date
