Chemical disinfectants and antiseptics - Quantitative non-porous surface test for the evaluation of virucidal activity of chemical disinfectants and antiseptics used in the veterinary area - Test method and requirements - Phase2, step2

This European Standard specifies a test method and the minimum requirements for virucidal activity of chemical disinfectant and antiseptic products that form a homogeneous physically stable preparation when diluted with hard water, or - in the case of ready-to-use-products - with water.
This European Standard applies to products that are used in the veterinary area on non-porous surfaces without mechanical action i.e. in the breeding, husbandry, production, veterinary care facilities, transport and disposal of all animals except when in the food chain following death and entry to the processing industry.
EN 14885 specifies in detail the relationship of the various tests to one another and to "use recommendations".
NOTE 1   The method described is intended to determine the activity of commercial formulations or active substances under the conditions in which they are used.
NOTE 2   This method corresponds to a Phase 2 Step 2 test.
NOTE 3   Using this European Standard, it is possible to determine the virucidal activity of the undiluted product.
NOTE 4   This standard uses Porcine Parvovirus because Bovine Enterovirus Type 1 (ECBO) virus used in the suspension test EN 14675 cannot be used for surface testing because of its loss of titre during drying. Porcine
Parvovirus has comparable resistance to ECBO virus.

This draft amendment is submitted to CEN members for enquiry. It has been drawn up by the Technical Committee CEN/TC 216.

This draft amendment A1, if approved, will modify the European Standard EN 17122:2019. If this draft becomes an amendment,
CEN members are bound to comply with the CEN/CENELEC Internal Regulations which stipulate the conditions for inclusion of
this amendment into the relevant national standard without any alteration.

This draft amendment was established by CEN in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CEN member into its own language and notified to the CEN-CENELEC
Management Centre has the same status as the official versions.

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

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
