6 Assessment and verification of the constancy of performance (AVCP)
6.1 General
The compliance of pipes and fittings with the requirements of this standard and with the declared values
(including classes) shall be demonstrated by:
 initial 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 product.
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, CWFT and conventionally
accepted performance).
Assessment previously performed in accordance with the provisions of this standard, respectively standards
as referenced in clause 2, 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 1 Same AVCP system means testing by an independent third party (only for reaction to fire and products
covered by AVCP system 1 and 3), under the responsibility of a notified product certification body (only for products
covered by AVCP system 1).
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.
NOTE 2 Products may be in different families for different characteristics.
NOTE 3 Reference to the assessment method standards should be made to allow the selection of a suitable
representative sample.
For Type Testing the following family groups apply:
a) Pressure groups for pipes and fittings as given in Table 12.

b) Size groups for pipes and fittings as given in Table 3.

3 All fittings except those included in group 1
and group 2.
In addition, the determination of the product type shall be performed for all characteristics included in the
standard for which the manufacturer declares performances:
 at the beginning of the production of a new or modified pipe or fitting design, the raw material or supplier
of the components; 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 pipe and fitting
design, in the raw material or in the supplie
