AFNOR NF T 72-281 standard: all you need to know

What is the AFNOR NF T 72-281 standard and what are the germs tested?

WHAT IS THE AFNOR NF T 72-281 STANDARD FOR DISINFECTION OF SURFACES BY AIR (DSVA)?

The AFNOR NF T 72-281 standard for disinfection of surfaces by air established for more than 25 years by AFNOR Standardization, renewed in September 2014, makes it possible to reference, validate and certify the bactericidal, yuricidal, fungicidal, mycobactericidal, tuberculocidal efficacy , sporicide and virucide including bacteriophages from a pair of biocidal device / product from manufacturers of aerial surface disinfection systems (DSVA). The virucidal nature of the products recognized by the AFNOR NF T 72-281 standard therefore allows them to be effective against the SARS-CoV-2 responsible for Covid-19, among others. .

To be certified, the product or device must be tested in an independent laboratory accredited by COFRAC in order to ensure the technical competence and impartiality of the organism of control.

SURFACE DISINFECTION: HOW EFFECTIVE DEPENDING ON THE TYPE OF TREATMENT? 

Let us take the example of a surface from which the number of microorganisms (bacteria, viruses, etc.) to be eliminated is 1,000,000. We speak of "LOG" to express the degree of eradication of microorganisms. From a LOG to a higher LOG, the efficiency is multiplied by 10.

explication des LOG pour la norme AFNOR NF T 72-281

The biocidal efficacy requirements of AFNOR NF T 72-281 standard depend on the target organisms:

  • Bacteria : > reduction of 5 log
  • Spores: > reduction of 3 log
  • Mushrooms and yeasts : > reduction of 4 log
  • Viruses included phages: > reduction of 4 logs
  • Mycobacteria : > reduction of 4 logs

Initial conditions require a LOG above the LOG reduction target.

The method is intended to determine the disinfectant activity of the processes used in human and animal health, the food industry, the industrial sector, and communities.
It makes it possible to know the systems marketed according with the standard, that is to say having proved during the test their effectiveness in killing the strains proposed in the reference of the standard.
