This European Standard specifies a test method and the minimum requirements for bactericidal activity of chemical disinfectants 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 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 This method cannot be used to evaluate the activity of products against mycobacteria or bacterial spores.

Diese Europäische Norm legt ein Prüfverfahren und die Mindestanforderungen an die bakterizide Wirkung von chemischen Desinfektionsmitteln und Antiseptika fest, die bei Verdünnung mit Wasser standardisierter Härte oder – im Fall gebrauchsfertiger Produkte – mit Wasser eine homogene, physikalisch stabile Zubereitung bilden.
Diese Europäische Norm gilt für Produkte, die im Veterinärbereich auf porösen Oberflächen ohne mechanische Wirkung angewendet werden, d. h. bei der Aufzucht, Haltung, Produktion !in veterinärmedizinischen Gesundheitseinrichtungen," und beim Transport von Tieren sowie bei der Tierkörperbeseitigung, außer wenn die Tiere nach der Tötung durch Zuführung in die weiterverarbeitende Industrie in die Nahrungsmittelkette eintreten.
EN 14885 legt im Einzelnen die Beziehung der verschiedenen Prüfungen untereinander sowie zu den „Anwendungsempfehlungen“ fest.
ANMERKUNG 1 Das beschriebene Verfahren ist für die Bestimmung der Wirkung von handelsüblichen Zubereitungen oder Wirkstoffen unter den Bedingungen, unter denen sie verwendet werden, bestimmt.
ANMERKUNG 2 Dieses Verfahren entspricht einer Prüfung der Phase 2, Stufe 2.
ANMERKUNG 3 Dieses Verfahren kann nicht angewendet werden, um die Wirkung von Produkten gegen Mykobakterien oder bakterielle Sporen zu bewerten.

Introduction
This document specifies a surface test for establishing whether a chemical disinfectant or antiseptic, for
use on porous surfaces without mechanical action, in the veterinary area. has or does not have
bactericidal activity under the laboratory conditions defined by this document, which influence the
action of disinfectants in practical use.
The laboratory test takes into account practical conditions of application of the product including pre-
drying test organisms and interfering substances on a surface, contact time and temperature, i.e.
conditions which may influence its action in practical situations.
The conditions are intended to cover general purposes and to allow reference between laboratories and
product types. Each utilization concentration of the chemical disinfectant or antiseptic, found by this
test corresponds to the chosen experimental conditions. However, for some applications, the
instructions of use of a product can differ and therefore additional test conditions need to be used.
1 Scope
This European Standard specifies a test method and the minimum requirements for bactericidal activity
of chemical disinfectants 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 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 This method cannot be used to evaluate the activity of products against mycobacteria or bacterial
spores.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in EN 14885 apply.
4 Requirements
The product shall demonstrate at least a 4 decimal log (lg) reduction from a water control, when tested
in accordance with Table 1 and Clause 5 under simulated soiling (3,0 g/l bovine albumin).

NOTE For the additional conditions, the concentration defined as a result can be

Any additional specific bactericidal activity shall be determined in accordance with 5.2.1 and 5.5.1.1 in
order to take into account intended specific use conditions.
5 Test method
5.1 Principle
A test suspension of bacteria mixed with interfering substance is inoculated onto the test surface and
dried. After the drying time the test surface is immersed into a sample of the product as delivered
and/or diluted with hard water (for ready to use products: water) ensuring that the test surface is
totally covered for one minute. The test surface is removed from the product solution and maintained at
a specified temperature for a defined period of time specified in Clause 4 and 5.5.1.1. At the end of that
contact time, the test surface is transferred to a neutralizer so that the action of the disinfectant is
immediately neutralized. The bacteria are removed from the surface by ultrasound treatment. T
