Disinfectant Efficacy Testing

Disinfectant testing is used to validate the microbicidal activity of disinfectant products. On the basis of the intended use of disinfectants, test microorganisms and other laboratory conditions are selected for their efficacy testing.

Why Disinfectant Testing is Important?

Surface disinfection plays a crucial role to prevent cross-infection that happens due to the contact with contaminated surfaces. Disinfectants and antiseptics (such as hand rubs and handwashes) are extensively used for disinfection and hygiene practices. The biocidal action of disinfectants helps in eliminating the pathogenic microbes (bacteria, viruses, fungi, etc) present on inanimate objects. While antiseptics are used to kill or prevent the growth of pathogens from skin surfaces.

Before launching disinfectant and antiseptic products in the market or using it in real conditions, it is pertinent to evaluate the manufacturer’s efficacy recommendations. The efficacy of disinfectants and antiseptics is measured by their “log reduction” value. Log reduction is a mathematical term used to define the relative number of living microorganisms that disinfectant eliminates in a given amount of time. And to make the performance claims, a disinfectant product needs to achieve a 5-log reduction value against the test microorganisms, which means that the sample inactivates (kills) 99.999 % of microbes.

Disinfectant and Sanitizer Test Methods

At Microbe Investigations, we perform following antibacterial and antiviral efficacy test for surface disinfectants and antiseptic formulations –

  • EN 1276 : 2019 – Quantitative suspension test for the evaluation of bactericidal activity of chemical disinfectants and antiseptics used in food, industrial, domestic and institutional areas 
  • EN 14476 : 2013+A2 : 2019 – Quantitative suspension test for the evaluation of virucidal activity in the medical area
  • EN 13697 : 2015+A1 : 2019 –  Quantitative non-porous surface test for the evaluation of bactericidal and/or fungicidal activity of chemical disinfectants used in food, industrial, domestic and institutional areas
  • EN 16615 : 2015Evaluation of bactericidal and yeasticidal activity of disinfectant wipes used in the medical area
  • EN 1650 : 2019Quantitative suspension test for the evaluation of fungicidal or yeasticidal activity of chemical disinfectants and antiseptics
  • PAS 2424 : 2015Quantitative Surface test for Antimicrobial efficacy (bactericidal and/or yeasticidal) of Disinfectants on hard porous surfaces
  • ASTM E1053 : 2011Standard to assess virucidal activity of chemicals intended for disinfection of inanimate and nonporous environmental surfaces
