ISO 21702

Measurement of antiviral activity on plastics and other non-porous surfaces

Summary

ISO 21702 is a standard test method to evaluate antiviral properties of plastics and other non-porous surfaces 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 plastics or other non-porous surface materials) is quantitatively determined.

Typical Test Substances

• Pre-treated/pre-coated plastics or other non-porous surface materials

Outline of Test Procedure

• Test sample (pre-treated non-porous surface material)
• Add virus and allow it to absorb onto the sample
• Hold for contact time (24 hours as standard)
• Elute virus off into a neutralizer
• Assay for Infectious Virus (quantitative assay)

Regulatory Agencies / Purpose

• Various agencies 
• R&D and marketing
