6.1 General
The compliance of fibre-cement slates and fittings 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
- factory production control by the manufacturer, including product assessment.
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).
6.2 Type testing
6.2.1 General
Type tests shall be carried out on products as delivered. If several formats or sizes of the same nominal
thickness are being produced from the same composition and by the same production method, type tests only
need to be carried out on one size of each nominal thickness.
All characteristics listed in Table 2 shall be subject to product type determination, except reaction to fire Class
A1 without testing and external fire performance "deemed to satisfy" products.
Product type determination shall be performed to demonstrate conformity to this standard. Tests previously
performed in accordance with the provisions of this standard (same product, same characteristic(s), test
method, sampling procedure, same attestation of conformity, etc.) may be taken into account. In addition,
product type determination shall be performed for the approval of a new product, or a fundamental change in
formulation or method of manufacture, the effects of which cannot be predicted on the basis of previous
experience.
Whenever a change occurs in the fibre-cement slate design, the raw material or supplier of components or the
production process, which would change significantly one or more of the characteristics, the type test shall be
performed for the appropriate characteristic(s).
6.2.2 Test samples, testing and compliance criteria
The number of samples of fibre-cement slates to be tested / assessed shall be in accordance with Table 2 of
this standard.

shall be retained by the manufacturer for at least 10 years after the last date of production of the fibre-cement
slates and fittings to which they relate.

6.3 Factory production control (FPC)
6.3.1 General
The manufacturer shall establish, document and maintain a 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.
All the elements, requirements and provisions adopted by the manufacturer shall be documented in a
systematic manner in the form of written policies and procedures.

This factory production control system documentation shall ensure a common understanding of the evaluation
of the constancy of performance and enable the achievement of the required product performances and the
effective operation of the production control system to be checked. Factory production control therefore brings
together operational techniques and all measures allowing maintenance and control of the compliance of the
product with the declared performances of the essential characteristics.
6.3.2 Requirements
6.3.2.1  General
The manufacturer is responsible for organizing the effective implementation of the FPC system in line with the
content of this product standard. Tasks and responsibilities in the production control organization shall be
documented and this documentation shall be kept up-to-date.

The responsibility, authority and the relationship between personnel that manages, performs or verifies work
affecting product constancy, shall be defined. This applies in particular to personnel that need to initiate
actions preventing product non-constancies from occurring, actions in case of non-constancies and to identify
and register product constancy problems.

Personnel performing work affecting the constancy of performance of the product shall be competent on the
basis of appropriate education, training, skills and experience for which records shall be maintained.

In each factory the manufacturer may delegate the action to a person having the necessary authority to:

- identify procedures to demonstrate constancy of performance of the product at appropriate stages;
- identify and record any instance of non-constancy;
- identify procedures to correct instances of non-constancy.

The manufacturer shall draw up and keep up-to-date documents defining the factory production control. The
manufacturer's documentation and procedures should be appropriate to the product and manufacturing
process. The FPC system should achieve an appropriate level of confidence in the constancy of performance
of the product. This involves:

a) the preparation of documented procedures and instructions relating to factory production control
operations, in accordance with the requirements of the technical specification to which reference is made;
b) the effective implementation of these procedures and instructions;
c) the recording of these operations and their results;
d) the use of these results to correct any deviations, repair the effects of such deviations, treat any resulting
instances of non-conformity and, if necessary, revise the FPC to rectify the cause of non-constancy of
performance.
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.

6.3.2.2 Equipment

Sampling from continuous production testing

- on the base sheet prior to coating,

- in conditions other than in Table 4,

is acceptable provided that it has been statistically established (see Annex B) that compliance with the
requirements given in Table 1 is ensured.

Acceptance tests can also be used to confirm that a batch of slates or fittings conforms with the standard, e.g.
in conjunction with type tests or for receiving inspection.

The tests include the:
- measurement of dimensions – length, width and thickness – (methods specified in 7.2);

- measurement of apparent density (slates only, method specified in 7.3.1);
- - measurement of mechanical characteristics–bending strength–(slates only, method specified in
7.3.2).
Each limit of specification, for the characteristics in Table 3, shall be subject to an AQL of 4 %. The
sampling schemes provided in ISO 2859-1 and ISO 3951-1, with an AQL of 4 % and inspection levels
respectively ensure that for large batches approximately 95 % of the items fulfill the
S1 and S
3 ,
requirements.
6.3.2.7 Non-complying products
The manufacturer shall have written procedures which specify how non-complying products shall be dealt
with. Any such events shall be recorded as they occur and these records shall be kept for the period defined
in the manufacturer’s written procedures.

Where the product fails to satisfy the acceptance criteria, the provisions for non-complying products shall
apply, the necessary corrective action(s) shall immediately be taken and the products or batches not
complying shall be isolated and properly identified.
Once the fault has been corrected, the test or verification in question shall be repeated.

The results of controls and tests shall be properly recorded. The product description, date of manufacture, test
method adopted, test results and acceptance criteria shall be entered in the records under the signature of the
person responsible for the control/test.
With regard to any control result not meeting the requirements of this European Standard, the corrective
measures taken to rectify the situation (e.g. a further test carried out, modification of manufacturing process,
disposal, recycle or correction of product) shall be indicated in the records.

6.3.2.8 Corrective action
The manufacturer shall have documented procedures that instigate action to eliminate the cause of non-
conformities in order to prevent recurrence.

6.3.2.9 Handling, storage and packaging
The manufacturer shall have procedures providing methods of product handling and shall provide suitable
storage areas preventing damage or deterioration.
6.3.3 Product specific requirements
The FPC system shall address this European Standard and ensure that the products placed on the market
comply with the declaration of performance.

The FPC system shall include a product specific FPC, which identifies procedures to demonstrate compliance
of the product at appropriate stages, i.e.:

a) the controls and tests to be carried out prior to and/or during manufacture according to a frequency
laid down in the FPC test plan,

and/or
b) the verifications and tests to be carried out on finished products according to a frequency laid down in
the FPC test plan
The manufacturer shall establish and maintain records that provide evidence that the production has been
sampled and tested. These records shall show clearly whether the production has satisfied the defined
acceptance criteria and shall be available for at least three years.

6.3.4 Initial inspection of factory and of FPC
Initial inspection of factory and of FPC shall be carried out when the production process has been finalised
and in operation. The factory and FPC documentation shall be assessed to verify that the requirements of
6.3.2 and 6.3.3 are fulfilled.

During the inspection it shall be verified:
a) that all resources necessary for the achievement of the product characteristics included in this European
Standard are in place and correctly implemented,

and
b) that the FPC-procedures in accordance with the FPC documentation are followed in practice,

and
c) that the product complies with the product type samples, for which compliance of the product
performance to the DoP has been verified.

All locations where final assembly or at least final testing of the relevant product is performed, shall be
assessed to verify that the above conditions a) to c) are in place and implemented. If the FPC system covers
more than one product production line or production process, and it is verified that the general requirements
are fulfilled when assessing one product, production line or production process, then the assessment of the
general requirements does not need to be repeated when assessing the FPC for another product, production
line or production process.
All assessments and their results shall be documented in the initial inspection report.

6.3.5 Continuous surveillance of FPC
Surveillance of the FPC shall be undertaken once per year. The surveillance of the FPC shall include a review
of the FPC test plan(s) and production process(s) for each product to determine if any changes have been
made since the last assessment or surveillance.

Checks shall be made to ensure that the test plans are still correctly implemented and that the production
equipment is still correctly maintained and calibrated at appropriate time intervals.

The records of tests and measurements made during the production process and to finished products shall be
reviewed to ensure that the values obtained still correspond with those values for the samples submitted to
the determination of the product type and that the correct actions have been taken for non-compliant products.

6.3.6 Procedure for modifications
If modifications are made to the product, production process or FPC system that could affect any of the
product characteristics declared according to this standard, then all the characteristics for which the
manufacturer declares performance, which may be affected by the modification, shall be subject to the
determination of the product type, as described in 6.2.1.

Where relevant, a re-assessment of the factory and of the FPC system shall be performed for those aspects,
which may be affected by the modification.

All assessments and their results shall be documented in a report.

6.4 Inspection of a consignment of finished products
Inspection of a consignment of finished products is not a requirement of this standard but if, in special cases, it
is demanded, it may be carried out in accordance with Annex A, ISO 2859-1 and ISO 3951-1.
