(Amendment)WC pans and WC suites with integral trap
WC pans and WC suites with integral trap
This European Standard specifies constructional and performance requirements together with test methods for close-coupled suites, one-piece and independent WC pans with integral trap used for personal hygiene manufactured from glazed ceramics or stainless steel.
This European Standard does not apply to squatting toilets, WC pans without integral trap or flushing cisterns as separate appliances.
In the case of independent WC pans, the associated flushing cisterns and pressure valves are covered by other standards and the reference to cisterns in this standard is related only to the definition and requirements of flushing volume.
In the case of close-coupled suites and one-piece WCs, this standard also specifies design, performance requirements and the test methods for designated flushing cisterns with flushing mechanisms, inlet valves and overflows. For these products, this standard covers flushing cisterns designed to be connected to drinking water installations inside buildings.
Before installation of WCs, EN 12056-2 and national requirements need to be taken into consideration.

Close-coupled suites, one-piece and independent WC pans with integral trap belong always to one class and
type at least. For each class and type a set of requirements to be tested (see 9.2.2) is defined. Due to this a
close-coupled suite, one-piece and independent WC pan with integral trap can be described with a
designation code which includes all fulfilled essential requirements.
The relevant product characteristics and the Essential Characteristics for close-coupled suites, one-piece and
independent WC pans with integral trap including their abbreviations are given in Tables 4 and 5.

5 Modification to Clause 8, Evaluation of conformity
Replace the former Clause 8 (now to be renumbered as Clause 9) with the following one:
“
9 Assessment and verification of constancy of performance – AVCP
9.1 General
The compliance of close-coupled suites, one-piece and independent WC pans with integral trap with the
requirements of this standard and with the performances declared by the manufacturer in the DoP shall be
demonstrated by:
— determination of the product type (see 9.2);
— factory production control by the manufacturer (FPC), including product assessment (see 9.3).
The manufacturer shall always retain the overall control and shall have the necessary means to take
responsibility for the conformity of the product with its declared performance(s).
9.2 Type testing
9.2.1 General
All performances related to characteristics included in this standard shall be determined when the
manufacturer intends to declare the respective performances unless the standard gives provisions for
declaring them without performing tests. (e.g. use of previously existing data, CWFT and conventionally
accepted performance).
Assessment previously performed in accordance with the provisions of this standard, may be taken into
account provided that they were made to the same or a more rigorous test method, under the same AVCP
system on the same product or products of similar design, construction and functionality, such that the results
are applicable to the product in question.
For the purposes of assessment, the manufacturer's products may be grouped into families, where it is
considered that the results for one or more characteristics from any one product within the family are
representative for that same characteristics for all products within that same family.
Products may be grouped in different families for different characteristics.
Reference to the assessment method standards should be made to allow the selection of a suitable
representative sample.
In addition, the determination of the product type shall be performed for all characteristics included in the
standard for which the manufacturer declares the performance:
— at the beginning of the production of a new or modified close-coupled suites, one-piece and independent
WC pans with integral trap (unless a member of the same product range), or
— at the beginning of a new or modified method of production (where this may affect the stated properties);
or
— they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the modified
close-coupled suites, one-piece and independent WC pans with integral trap design, in the raw material

or in the supplier of the components, or in the method of production (subject to the definition of a family),
which would affect significantly one or more of the characteristics.
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of assessment methods of other product standards, these characteristics need not
be re-assessed. The specifications of these components shall be documented.
Products bearing regulatory marking in accordance with appropriate harmonized European specifications may
be presumed to have the performances declared in the DoP, although this does not replace the responsibility
on the close-coupled suites, one-piece and independent WC pans with integral trap manufacturer to ensure
that the close-coupled suites, one-piece and independent WC pans with integral trap as a whole is correctly
manufactured and its component products have the declared performance values.
9.2.2 Test samples, testing and compliance criteria
The number of samples of close-coupled suites, one-piece and independent WC pans with integral trap to be
tested/assessed shall be in accordance with Table 6 and/or Table 7.

The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed
on the market comply with the declared performance of the essential characteristics.
The FPC system shall consist of procedures, regular inspections and tests and/or assessments and the use of
the results to control raw and other incoming materials or components, equipment, the production process and
the product.
The results of inspections, tests or assessments requiring action shall be recorded. The action to be then
when control values or criteria are not met shall be recorded.
NOTE Manufacturers having an FPC system which complies with EN ISO 9001 and which addresses the provisions
of the present European Standard are considered as satisfying the FPC requirements of the Regulation (EU)
No. 305/2011.
