Textiles – Determination of antiviral activity of textile products

Summary

ISO 18184 is a standard test method to evaluate antiviral properties of textile products that are pre-treated/pre-coated with an antimicrobial active ingredient(s).  The level of viral inactivation upon direct contact with the test sample (pre-treated textile) is quantitatively determined.

Typical Test Substances

• Pre-treated/pre-coated fabrics
• Pre-treated/pre-coated face masks
• Pre-treated/pre-coated air filters

Outline of Test Procedure

• Test sample (pre-treated textile) 
• Add virus and allow it to absorb onto the sample 
• Hold for contact time (2 hours as standard; ranging from 5 minutes to 24 hours)
• Elute virus off into a neutralizer
• Assay for Infectious Virus (quantitative assay)
