WC and urinal flushing cisterns

This European Standard specifies design, performance requirements and the test methods for WC and urinal flushing cisterns with flushing mechanism, inlet valve and overflow.
This document covers flushing cisterns designed to be connected to drinking water installations inside buildings.
This standard does not cover automatic valveless siphon flushing cisterns for flushing urinals.
NOTE   Flushing cisterns for one-piece WCs and close-coupled suites are covered by EN 997.

The intended use of WC and urinal flushing cisterns is personal hygiene in accordance with the scope of this

standard.

NOTE The intended use is also mentioned in Annex ZA, Tables ZA.1.1, ZA.1.2 and ZA.1.3. The abbreviation “PH” for

the intended use personal hygiene might be used for CE marking.

A schematic drawing of the product may optionally follow the abbreviation for personal hygiene.

WC and urinal flushing cisterns belong always to one class and type at least. For each class and type a set of

requirements to be tested (see 11.2.2) is defined. Due to this a WC and urinal flushing cistern can be

described with a designation code which includes all fulfilled essential requirements.

The relevant product characteristics and the Essential Characteristics for WC and urinal flushing cisterns

including their abbreviations are given in Tables 5, 6 and 7.

6 Modification to Clause 11, Evaluation of conformity
Replace the whole clause with the following one:
11 Assessment and verification of constancy of performance – AVCP
11.1 General

The compliance of WC and urinal flushing cisterns 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 11.2);

— factory production control by the manufacturer (FPC), including product assessment (see 11.3).

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).

11.2 Type testing
11.2.1 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.
---------------------- Page: 10 ----------------------
SIST EN 14055:2011/kFprA1:2015
EN 14055:2010/FprA1:2014 (E)

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 WC and urinal flushing cisterns (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

WC and urinal flushing cisterns 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 WC and urinal flushing cisterns manufacturer to ensure that the WC and urinal flushing cisterns as a

whole is correctly manufactured and its component products have the declared performance values.

11.2.2 Test samples, testing and compliance criteria

The number of samples of WC and urinal flushing cisterns to be tested/assessed shall be in accordance with

Table 8 and/or Table 9 and/or Table 10.
