Plastics & non-porous surfaces
Standard / Test method
ISO 21702
Quantitative assessment of antiviral activity on plastics and other non-porous surfaces using bacteriophages as viral models. Testing is performed using a method adapted from ISO 21702.
Overview
ISO 21702 describes a standardised test method for quantitatively assessing antiviral activity on plastics and other non-porous surfaces.
Typical applications include functionalised materials, coatings and the assessment of new material developments with antiviral properties.
In our laboratory, different bacteriophages can be used as viral surrogates in adapted test designs based on ISO 21702. Depending on the testing objective, suitable phages are selected as models for enveloped or non-enveloped viruses. Quantitative evaluation is based on comparing the numbers of infectious phage particles recovered from treated and untreated test surfaces.
Depending on your testing objective, sample type, sample size, contact time or requested test strains, we can assess whether project-specific adaptations to the test design are appropriate.
Typical applications
Antiviral surfaces
Assessment of surfaces with antiviral treatments or functional coatings using bacteriophage models.
Product development
Comparison of new materials and surfaces for antiviral properties using selected viral models.
Material qualification
Assessment of antiviral activity using bacteriophage models for technical and industrial applications.
Frequently asked questions
Which materials are suitable for testing based on ISO 21702?
Testing based on ISO 21702 is particularly suitable for plastics and other non-porous surfaces with antiviral treatments or coatings.
What does ISO 21702 assess?
ISO 21702 assesses antiviral activity on surfaces. In our laboratory, bacteriophages are used as viral surrogates in adapted test designs based on this standard.
Why are bacteriophages used as viral surrogates?
Selected bacteriophages provide practical viral models for controlled laboratory testing. Depending on the testing objective, suitable phages are chosen as models for enveloped or non-enveloped viruses. Results relate to the selected surrogate and test conditions and cannot automatically be generalised to all viruses.
What is the difference between ISO 21702 and ISO 22196?
ISO 21702 addresses antiviral activity on plastics and other non-porous surfaces. ISO 22196 assesses antibacterial activity on comparable materials. Our antiviral testing uses bacteriophage models in a method adapted from ISO 21702.
