Several dozens of official antimicrobial efficiency test exists in relation
to disinfectant evaluation.
These protocols are published by I.S.O. and the A.O.A.C.
You will find the protocols are application specific.
In brief :
Most involve challenge of a "use dilution" with a specific level and range
of organisms for a specified time and at a specified temperature. Most
involve assessment in the absence and presence of organic challenge.
Efficiency of disinfectants is most commonly assed in terms of log kill by
comparison of the post challenge survivors after neutralisation with the
level of organisms attained at the point of challenge.
As most official tests involve challenge with CLASS II pathogens you may
wish to question whether or not it safe to conduct the work in your own
Hope this helps orient you
