European foreword
This document (EN 17122:2019/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.

1 Modification to the European foreword
After the third paragraph, add the following new paragraph:
“This document has been amended to harmonise the terminology and methods with those adopted recently for
other similar European standards and to make minor editorial changes to improve clarity. A minor technical error
has also been corrected. The changes detailed above have no impact on the test results obtained using the previous
version. Those results are still valid.”
2 Modification to Contents
Change the entry for Annex B to “Annex B Determination of the residual virus titre by the large-volume- plating
(LVP) method”
Change the Title of Annex E to “Virucidal activity and activity against enveloped viruses”
3 Modification to Clause 2, Normative References
Add, between the references to EN 14885 and EN 10088-2:
“EN 10088-1, Stainless steels — Part 1: List of stainless steels”
4 Modification to Clause 4, Requirements for virucidal activity on surfaces
Delete the word “full” in the second sentence of the first paragraph, in the note and in the heading of Table 1.
5 Modification to 5.2.2.4, Neutral Red (1:1000 solution)
Replace “0,44 µm” with “0,45 µm”.
6 Modification to 5.5.1, Experimental conditions
Delete the word “full” in the second sentence of clause c.
7 Modification to 5.5.2, Test procedure
Change the sub-heading a to “a) Quantal tests (end point titration) – [the procedures 1) and 2) are alternatives]”
8 Modification to 5.5.3.3, Elimination of cytotoxicity
Delete the whole text of this subclause and replace with:
“If the cytotoxicity is so great that the reduction (5.8.2) cannot demonstrate the range of 3 lg TCID ,
50 special
techniques shall be used, such as determination of the residual virus titre by the large-volume- plating (LVP)
method (Annex B).
Appropriate controls are required to demonstrate that the procedure does not reduce the infectivity of the virus.
The virucidal activity is measured by comparing the titres of the treated and untreated viral suspensions. Use
