NF T 72-281 is a French standard for determining bactericidal, fungicidal and sporicidal activity for airborne surface disinfection. The test is carried out in an independent laboratory, which must be COFRAC accredited.<\/p>\n

Test process for standard NF T 72-281<\/h2>\n

It consists of positioning the machine (the diffuser) in the middle of an airtight room and then placing stumps behind the machine in different places to check that the disinfectant product being propelled reaches all the surfaces in contact with the air in the room. No flow rate is required by the standard, and IBL Specifik obtained results that exceeded the requirements of the standard with a flow rate of around 8ml\/m3. At the end of the diffusion time, for the AIRBIO\/APABIO<\/a>A contact time of 2 hours is required to obtain results similar to those obtained when passing the standard.<\/p>\n

The following germs were tested:<\/h2>\n

Bactericidal activity<\/strong> Pseudomonas aeruginosa (CIP 103-467), Staphylococcus aureus (CIP 4.83), Enterococcus hirae (CIP 5855), Escherichia coli (CIP 54127)
\nSporicidal activity<\/strong> Bacillus subtilis spores (CIP 52 62)
\nActivated fungicide<\/strong> Candida albicans (IP 4872), Aspergillus niger (IP 1431-83)
\nYeast-killing activity<\/strong> Candida albicans (IP4872).<\/p>\n

SUMMARY <\/p>\n\n\n\n

NF T 72-281 is a French standard that establishes a method for assessing the antimicrobial activity of materials and surfaces in hospital and similar environments. It describes methods for testing the efficacy of antimicrobial products on surfaces using a suspension test method.<\/p>\n\n\n\n

The germs tested under this standard are as follows:<\/p>\n\n\n\n

    \n
  1. Staphylococcus aureus: a bacterium that can cause skin infections, respiratory tract infections and bloodstream infections.<\/li>\n\n\n\n
  2. Enterococcus hirae: a bacterium that can cause urinary tract infections, blood infections and other infections.<\/li>\n\n\n\n
  3. Escherichia coli: a bacterium commonly found in the intestine, but which can also cause urinary tract infections, intestinal infections and other infections.<\/li>\n\n\n\n
  4. Pseudomonas aeruginosa: a bacterium that can cause skin, respiratory, urinary tract and other infections.<\/li>\n<\/ol>\n\n\n\n

    In summary, the NF T 72-281 standard assesses the antimicrobial effectiveness of materials and surfaces against these four types of germs.<\/p>","protected":false},"excerpt":{"rendered":"
