EN 14675 Quantitative Suspension
Method for Virucidal Activity of
Chemical Disinfectants and
Antiseptics used in the
Veterinary Field
Test Purpose
The purpose of this test is to
determine the minimum virucidal
activity of a chemical
disinfectant used in the
veterinary field according to
the test method EN 14675 against
relevant viruses. The method
described is intended to
determine the virucidal activity
of chemical disinfectants on
viruses in the conditions in
which they are used.
Test Summary
A suspension of virus is added
to a solution of interfering
substances. A prepared test
solution of a product is added
to the suspension of virus in
interfering substances. The
mixture is maintained at the
requested temperature(s) for the
requested exposure time(s). At
the end of the exposure time,
aliquots are taken and the
virucidal activity against the
test virus in this portion is
immediately neutralized or
suppressed. The number of
surviving viral particles in the
test suspension are determined
by serial dilution. Appropriate
controls are also performed.
