5 Test methods Test methods are described in the specific parts of the EN 14617 series and in the specific annexes of this document. 6 Assessment and verification of constancy of performance – AVCP 6.1 General The compliance of slabs and cut-to-size products made of agglomerated stones 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 on the basis of type testing, — 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). SIST EN 16954:2018
EN 16954:2018 (E) 13 6.2 Type testing 6.2.1 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 or Classification Without Further Testing CWFT). 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. NOTE Same AVCP system means testing by an independent third party. — 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 slab and cut-to-size product made of agglomerated stones using a new type of rough slab, or — at the beginning of a new or modified method of production (where this may affect the stated properties); or they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the slabs and cut-to -size products made of agglomerated stones, in the rough slab, or in the method of production (subject to the definition of a family), which would affect significantly one or more of the characteristics. Where the rough slabs are used whose characteristics have already been determined, by the rough slabs manufacturer, on the basis of assessment methods of other product standards, these characteristics need not be re-assessed.

size products (cut to size slabs, special pieces, treads and risers) of agglomerated stones, which are
made for use as flooring and stairs in pedestrian areas for internal and external uses including those in
enclosed public transport premises. It also provides for the evaluation of conformity and marking of the
products to the requirements of this draft European Standard.
This draft European Standard covers tactility but only for products the intended use of which requires
this performance.

6 Assessment and verification of constancy of performance – AVCP
6.1 General
The compliance of slabs and cut-to-size products made of agglomerated stones 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 on the basis of type testing,
— 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
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 or Classification Without
Further Testing CWFT).
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.
NOTE Same AVCP system means testing by an independent third party.
— 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 slab and cut-to-size product made of
agglomerated stones using a new type of rough slab, or
— at the beginning of a new or modified method of production (where this may affect the stated
properties); or
they shall be repeated for the appropriate characteristic(s), whenever a change occurs in the slabs and
cut-to -size products made of agglomerated stones, in the rough slab, or in the method of production
(subject to the definition of a family), which would affect significantly one or more of the characteristics.
Where the rough slabs are used whose characteristics have already been determined, by the rough
slabs manufacturer, on the basis of assessment methods of other product standards, these
characteristics need not be re-assessed.
