ISO 21702 Measurement of Antiviral Activity on Plastics and Other Non-Porous Surfaces

ISO 21702 Measurement of Antiviral Activity on Plastics and Other Non-Porous Surfaces

The ISO 21702 standard, published by the International Standards Organization (ISO), defines appropriate test methods for measuring antiviral activity on plastics and other non-porous surfaces of products treated antivirally against certain viruses. However, due to individual sensitivities, results for one test virus may not be valid for other viruses.

ISO 21702 Measurement of Antiviral Activity on Plastics and Other Non-Porous Surfaces

Antibacterial treated porous and non-porous products are widely accepted and used among consumers for additional functions that differ from those of conventional materials in terms of material protection.

Other ISO standards for measuring antibacterial activity are also used. Namely,

  • The test method for measuring antibacterial activity in non-porous products is described in the ISO 22196 standard.
  • The test method for measuring antibacterial activity on porous products (textiles) is described in the ISO 20743 standard.
  • The test method for measuring antiviral activity on porous products (textiles) is described in the ISO 18184 standard.

The ISO 21702 standard is a test method for antiviral activity on non-porous products. While designing this standard, ISO 22196 and ISO 18184 standards were taken as a basis.

In the ISO 22196 standard, the scope has been expanded to cover surfaces made of plastic and other non-porous materials. Therefore, this standard is intended to be applicable to plastics, coating materials, ceramics, natural and artificial leather, stainless, rubbers and similar products.

The handling of potentially dangerous viruses and host cells requires a high degree of technical competence and is also subject to current legal regulations. Therefore, only personnel trained in biological techniques should perform such tests. During testing, strict adherence to appropriate practices for disinfection, sterilization, and personal hygiene is essential.

For the purposes of the ISO 21702 standard,

  • The term antiviral refers to the situation where the number of infectious virus particles on the surfaces of the products is reduced.
  • The expression antiviral agent refers to agents that reduce the number of infectious viruses on the surface of products.
  • The expression antiviral activity refers to the difference in infectivity of the virus in an antiviral-treated product and an untreated product after vaccination and contact with the virus.

Among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors, our organization also provides services for the measurement of antiviral activity on plastics and other non-porous surfaces, within the scope of ISO 21702 standard, with its trained and expert staff and advanced technological equipment.
