European foreword
This document (EN 17272:2020/prA1:2023) has been prepared by Technical Committee CEN/TC 216
“Chemical disinfectants and antiseptics”, the secretariat of which is held by AFNOR.
This document is currently submitted to the CEN-Enquiry
This document will supersede EN 17272:2020.
A significant number of the modifications listed in this amendment are editorial and the result of re-
ordering the text within the standard. To allow users to quickly ascertain and understand the key
technical amendments and / or clarifying text that have been introduced to EN 17272, the modifications
have been listed in two sections. The first section presents the sections with fundamental technical
changes driven by the amendment and the second section the solely editorial amendments.

1.1 Modifications to the Foreword
Add in the end the following sentence:
“Results obtained using the 2020 version of the standard prior to the amendment remain valid.”
1.2 Modification to 5.2.2.2.8 (old) to 5.2.2.2.7 (new)
Replace the reference behind Tryptone salt with “(5.2.2.2.7)” and add in the last paragraph the following
sentence:
“In this case, water (5.2.2.2.1) can be used as diluent.”
Change “Bacteria, fungi, yeast and spores” to “Bacteria, yeast, fungi and spores”
1.3 Modification to 5.2.2.2.9 (old) to 5.2.2.2.8 (new)
Add in the list of composition 5,0 g polysorbate 80 and also in the preparation.
Add in the end a sentence for viruses. The whole modification reads as follows:
“Composition:
Tryptone, pancreatic digest of casein 1,0 g
Sodium chloride 8,5 g
Polysorbate 80 5,0 g
Water (see 5.2.2.2.1) to 1.000,0 ml
Preparation:
Dissolve the sodium chloride and tryptone in the water. Add polysorbate 80 and any neutralizing agent
specifically designed for the product under test.
Prepare the diluent in large-volume batches, then distribute into smaller adapted flasks. Sterilize in the
autoclave.
For mycobacteria, water (refer to 5.2.2.2.1) is used instead of diluents.
For viruses, preservation media (refer to 5.2.2.3.1) is used instead of diluents.”
1.4 Add new paragraph 5.2.2.4.8
Add the following new paragraph:
“5.2.2.4.8 Bacteriophage and virus recovery and rinsing liquid
For bacteriophage and virus, growth and preservation media (5.2.2.3.1) are used.”
1.5 Modification to 5.4.2.1 (old) 5.4.1.3.1. (new)

In the last paragraph replace “10 ” with “10 ”, to read:
“Increase the initial inoculum up to 5 × 10 and add to the interfering substance a 1/20 dilution rate of
skimmed milk.”

1.6 Modification to 5.5.1.2.1
Replace existing text with
“To be run in parallel with the efficacy and distribution tests”
1.7 Modification to 5.5.1.4.2
Replace
“Distribute the three carriers strain-by-strain at a height (H) in the range 1 to 1,5 m and at a distance (D)
as defined in the table in Annex B according to the volume of the enclosure.
Position of the carriers: vertical.
Orientation: microbial inoculum facing away from the release source.”
with
“Distribute the carriers strain-by-strain in accordance with Annexes A and B.
For the efficacy test:
Position of the carriers: vertical.
Orientation: microbial inoculum facing away from the release source.
For the distribution test:
Position and orientation of the carriers shall be in accordance with Annex A (also see Figures E.5, E.6 and
E.7)
NOTE The position of the diffusion device remains identical for the efficacy and distribution tests. The distance
from the diffusion device to each carrier in the distribution test is not expected to be equal.”
1.8 Modification to 5.5.2.2.1c)
Replace
“Once the ADC time and the ensuing aeration time, if applicable, have elapsed, recover the carriers and
transfer them to 20 ml of recovery liquid to neutralize the action of the product.
This gives the recovery solution S.
Neutralization by means of dilution effect or by adding a specific agent should be explained in the report.
Incomplete neutralization of the residue shall invalidate the tests.”
with
“Once the ADC time and the ensuing aeration time, if applicable, have elapsed, recover the carriers and
transfer them to 20 ml of recovery liquid (refer to 5.2.2.2.9) to neutralize the action of the product.
The quantity of recovery liquid may be reduced provided that its neutralizing potential remains adequate.
This gives the recovery solution S.”
1.9 Addition of new 5.5.2.2.2
Add after new 5.5.2.2.1 the following new paragraph:
“5.5.2.2.2 Cytotoxicity
Solution S is diluted from 10-1 to 10-4.
