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.

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);

— 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

---------------------- Page: 9 ----------------------

EN 997:2012/FprA1:2014 (E)

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.

9.3 Factory production control (FPC)
9.3.1 General

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
