Foreword
This European Standard has been prepared by Technical Committee CEN/TC 191 "Fixed fire fighting
systems", the secretariat of which is held by BSI.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by September 2001, and conflicting national standards shall
be withdrawn at the latest by December 2002.
This European Standard has been prepared under a mandate given to CEN by the European Commission
and the European Free Trade Association, and supports essential requirements of EU Directive(s).
According to the CEN/CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic,
Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,
Portugal, Spain, Sweden, Switzerland and the United Kingdom.
For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this standard.
It forms one Part of EN 12259, covering components for automatic sprinkler systems and is included in a
series of European Standards planned to cover:
1
a) automatic sprinkler systems (EN 12259 & 12845)

8 Evaluation of conformity
8.1 General
The compliance of a wet alarm valve assembly with the requirements of this standard shall be
demonstrated by:
- initial type testing
- factory production control by the manufacturer.
8.2 Initial type testing
Initial type testing shall be performed on first application of this standard. Tests previously performed in
accordance with the provisions of this standard (same product, same characteristic, test method, sampling
method and system of attestation of conformity) may be taken into account. In addition, initial type testing
shall be performed at the beginning of the production of a product type or at the beginning of a new
method of production (where these may affect the stated properties).
All characteristics given in clause 4, and where appropriate clause 5, shall be subject to initial type testing.
8.3 Factory production control (FPC)
The supplier shall establish, document and maintain an FPC system to ensure that the products placed on
the market conform with the stated performance 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. It shall be sufficiently detailed to ensure that the conformity of the product is
apparent, ensuring detection of irregularities at the earliest possible stage.
An FPC system conforming with the requirements of the relevant part(s) of EN ISO 9000, and made
specific to the requirements of this standard, shall be considered to satisfy the above requirements.
The results of inspections, tests or assessments requiring action shall be recorded, as shall any action
taken. The
