Overview

Airmid Healthgroup conducts antiviral activity testing on fine ceramics and semiconducting photocatalytic materials to assess their effectiveness under indoor lighting conditions.

Using the ISO 18071 standard, this test provides quantitative data on the antiviral properties of non-porous photocatalytic surfaces when exposed to viruses under controlled lighting conditions. This independent validation supports manufacturers in substantiating their antiviral claims for use in construction and interior materials.

Products That Can Be Tested

This test is designed for non-porous, indoor-light-active photocatalytic materials used in construction and interior applications, including:

  • Flat sheets, boards, and plates
  • Coatings and treated surfaces
  • Architectural and decorative panels
  • Antiviral surface treatments for public spaces

These materials are commonly used in healthcare, commercial, and residential environments where surface hygiene is a priority.

Description of the Test Process

  1. Virus Exposure: The test material is inoculated with an appropriate virus and exposed to a halophosphate fluorescent lamp at a predefined intensity for a duration of 2 to 8 hours.

  2. Control & Experimental Conditions: Parallel tests are conducted on treated and untreated materials under both light and dark conditions to evaluate photocatalytic antiviral activity accurately.

  3. Test Repetition & Validation: The test is performed in triplicate to ensure consistent and reproducible results.

  4. Adaptability to Other Viruses: While the test method is written for bacteriophage Q-beta, the protocol can be adapted for other biosafety level 2 viruses or bacteriophages, depending on specific testing requirements.

Benefits of Antiviral Testing with Airmid Healthgroup

  • Scientifically Validated Claims: Independent testing under ISO 18071 ensures robust support for antiviral performance claims.
  • Real-World Application: Testing replicates indoor lighting conditions to provide relevant and actionable insights into material performance.
  • Competitive Advantage: Third-party validation enhances consumer trust and helps differentiate antiviral photocatalytic materials in the market.

Third-Party Validation & Market Advantages

Products that pass the ISO 18071 antiviral activity test can be labeled as independently tested by Airmid Healthgroup, providing manufacturers with credible data to support their claims in marketing, regulatory submissions, and product certifications.

Turnaround Time

Testing is typically completed within 4 to 6 weeks, allowing manufacturers to efficiently incorporate results into their product development and commercialization timelines.
