6 Evaluation of conformity
6.1 General
The compliance of a concrete roofing tile or fitting with the requirements of this document shall be
demonstrated by:
initial type testing; and
factory production control (FPC).
9
---------------------- Page: 10 ----------------------
EN 490:2004 (E)
For the purpose of testing, tiles and/or fittings may be grouped into families when it is considered that a given
characteristic or characteristics is/are common to all tiles and/or fittings within a family.
6.2 Type testing
Initial type testing shall be performed to demonstrate conformity to this document (see Table 2).
Tests previously performed to demonstrate conformity to the provisions of this document (same product, same
characteristic(s), same sampling regime, same system of attestation of conformity) may be taken into account.
All characteristics given in Table 2 shall, where relevant, be subject to initial type testing.
Whenever a change occurs in the product design or raw material, or the production process, which would
change significantly one or more of the stated characteristics, the type test shall be repeated for the
appropriate characteristic(s).
6.3 Factory production control (FPC)
The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed
on the market conform to the requirements of this document. The FPC system shall consist of procedures,
regular inspections and tests and/or assessments, to control raw or other materials or components, equipment,
the production process and the product. The FPC system shall be sufficiently detailed to ensure that the
conformity of the product is apparent.
The FPC system shall include the tests identified in the relevant column in Table 2.
The results of inspections, tests, or assessment requiring action and any action taken, shall be recorded. The
action to be taken when control values or criteria are not met shall be recorded.
An FPC system conforming to the requirements of EN ISO 9001, and made specific to the requirements of
this document, is considered to satisfy the requirements for FPC.
7 Sampling
7.1 Sampling for type tests
Tiles and fittings for type tests shall be sampled in accordance with the sampling plan given in Table 2 and the
sampling procedure given in Annex D.
A "day of production" is defined as any period within one 24 h day (or period) of production of roofing tiles or
fittings.
