Measurement of antiviral activity on plastics and other non-porous surfaces.
ISO 21702 is an antimicrobial surface test that performs the measurement of antiviral activity on plastics and other non-porous surfaces.
With the Current Corona outbreak this is a most vital test for the Si-Quat Coating. This standard is the standard used to certify the anti-viral activity of Si-Quat against viruses including the Sars-Cov-2 Virus.
Si-Quat has preformed at 10log 4.2 translating to little over 99.99% within 20 min.
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees.
As stated on the ISO Website:
Antibacterial-treated porous and non-porous products have been widely accepted and used among general consumers as their new choices to purchase for the additional function, which are different from what traditional materials had in terms of material protection.
Recently, antiviral-treated porous and non-porous products have been also in the market.
The measuring test method of antibacterial activity on non-porous products is described in ISO 22196.
The measuring test method of antibacterial activity on porous products (textiles) is described in ISO 20743.
The measuring test method of antiviral activity on porous products (textiles) is described in ISO 18184.
In ISO 22196, the scope has been expanded to include surfaces made of plastics and other non-porous materials, thus this document is intended to be applicable to products such as plastics, coating materials, ceramics, natural and artificial leathers, stainless, rubbers, etc.
ISO 21702 is a surface test generally used with the different viruses that can be replaced by others, in the case of Si-Quat this would be focused on Sars-Cov-2 for the moment.
The standard ISO 21702 test method is designed to test the ability of plastics and other similar non-pourose materials to kill viruses that have come into contact with the surface of the treated material. ISO 21702 is conducted over a 24 hour period of contact with the virus. Standard antiviral testing for ISO 21702 is conducted using Influenza A virus, Feline calicivirus, or coronavirus as examples.
To mimic a more real life scenario Si-Quat has been tested and passed an altered ISO 21702 conducted after 20 minutes. This was the fastest time measurement that could be taken by our lab partners.
Si-Quat Antimicrobial treated surfaces meet the requirements of ISO 21702. Contact us for test results.
Durability testing when combined with ISO 21702 or another antimicrobial test can provide important data on how a material will perform after exposure to conditions found in its intended use environment.
Si-Quat coatings are tested and certified to last over 12 months but are expected to not loose efficacy without friction applied.
