Bidets - Functional requirements and test methods
This European Standard specifies the functional requirements and test methods for bidets used for domestic purposes and made from either ceramics or stainless steel.
All drawings are examples only, other forms are permissible.
NOTE For the purposes of this standard the term ‘domestic purposes‘ includes use in hotels, accommodation for students, hospitals and similar buildings, except when special medical provisions are required.
Sitzwaschbecken - Funktionsanforderungen und Prüfverfahren
Dieses Dokument legt die wesentlichen Merkmale und Prüfverfahren zur Feststellung der Leistungsbestän digkeit von Bidets für den häuslichen Gebrauch fest, die für die persönliche Hygiene verwendet werden und entweder aus Keramik oder aus nichtrostendem Stahl bestehen.
Häusliche Zwecke schließen die Verwendung in Hotels, Studentenwohnheimen, Krankenhäusern und ähnli
chen Gebäuden ein, es sei denn, es sind besondere medizinische Vorkehrungen erforderlich.
Die ordnungsgemäße Funktion von Bidets kann nur dann vorausgesetzt werden, wenn sie an ein geeignetes Abflusssystem angeschlossen sind (siehe EN12056-2:2001 für weitere Informationen). Alle Zeichnungen sind nur Beispiele.
Bidets - Exigences fonctionnelles et méthodes d'essai
Le présent document spécifie les caractéristiques essentielles et les méthodes d’essai permettant d’établir la constance des performances des bidets à usage domestique, en céramique ou en acier inoxydable et destinés à être utilisés pour l’hygiène personnelle.
L’expression « à usage domestique » inclut l’utilisation en hôtels, en logements pour étudiants, en hôpitaux et autres bâtiments similaires, sauf si des précautions médicales particulières s’imposent.
Le bon fonctionnement des bidets ne peut être assuré que s'ils sont raccordés à un réseau d'évacuation approprié (voir l’EN 12056-2:2001 pour plus d’informations). Toutes les figures ne sont que des exemples.

except when special medical provisions are required.
Proper functioning of bidets can only be assumed when connected to a suitable drainage system (see
EN 12056-2:2001 for more information). All drawings are examples only.

areas of the bidet intended to or likely to come into contact with water during use
Note 1 to entry: Parts of the bidet with special function(s) are deemed to be excluded. Examples for areas with
special functions are inlet and outlet holes, outlet grills and overflow protection provisions
3.1.3
cleanability
characteristic which allows the functional surfaces to be self-draining, visibly smooth, non-absorbent and
free from unacceptable internal corners, such that they can be kept visibly free from dirt and/or stains
after use when subject to a regular maintenance regime
Note 1 to entry: This may include, when appropriate, specific instructions for use and care, as specified by the
manufacturer
3.2 Abbreviations
The following abbreviations can be used for marking (e.g. CE marking), independent of the language
version of this document and the language of the market where the product will be placed.

PH Personal hygiene
4 Characteristics
4.1 Cleanability
The functional surfaces of the bidet shall be tested in accordance with 5.2.
When tested in accordance with 5.2, bidets shall have smooth and readily cleansed non-absorbent
functional surfaces which are free from acute internal corners which would be difficult to clean, i.e.
surfaces intended to or likely to come into contact with water during use. Water inside the bowl of the
bidet shall drain out through the plug hole.
The stagnation of water due to surface tension is permitted.
The results can be expressed as follows:
• Both of the above requirements are met CA
4.2 Load resistance
When tested in accordance with 5.3., wall-hung bidets shall withstand a force of (4,00 ± 0,1) kN without
showing any evidence of cracking and/or permanent deformation.
The results can be expressed as follows:
• LR 4
4.3 Capacity to overflow
Bidets shall be tested in accordance with 5.4. in order to determinate the capacity of the overflow.

oSIST prEN 14528:2023
prEN 14528:2022 (E)
The performance shall be expressed by means of an overflow type dependent on the flow rate of the
overflow. The type of overflow corresponds to the capacity of the overflow given in Table 1. When tested
in accordance with 5.4, the flow rate of the overflow shall not be less than the values given in Table 1.
The results can be expressed in accordance with Table 1 “capacity level”:
• e.g: CL 25
The overflow can be either an integral overflow or an overflow device as specified by the manufacturer.

0,25 CL 25
0,20 CL 20
0,15 CL 15
0 CL 00
Products without an overflow shall be classified with CL 00.
5 Testing, assessment and sampling methods
5.1 General
All tests shall be carried out on the same sample bidet.
Install the bidet to be tested on a firm flat horizontal or vertical surface as appropriate with a layer of
mortar or other material to accommodate any unevenness in accordance with the manufacturer's
installation instructions.
5.2 Determination of cleanability
Test equipment:
• Water coloured with eosin or any other colouring agent
The concentration is about 0,1 g of eosin plus 0,1 g of standard (liquid) detergent per litre of water
(a different concentration and/or a different colouring agent may be used, depending on the colour
of the appliance, since the goal is to ensure a visual contrast with the appliance).
• Steel ball
Use a steel ball (⌀ (15 ± 0,5) mm, and in narrow areas of the bidet a ⌀ (11 ± 0,5) mm ball may be
used).
Test procedure:
• The bidet shall be made level on the mounting surface and in accordance with the manufacturer's
instructions. Clean the sample with a cleaning product recommended by the manufacturer or a
standard gentle detergent and a non-abrasive natural sponge. The purpose of this operation is to
remove all residues from the appliance (demoulding agent, grease, dust,
