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 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.
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) Size groups for pipes and fittings as given in Table 9.
Table 9 — Size groups
Size group Range of nominal diameters, d
n
1 32 ≤ d < 75
n
75 ≤ d < 200
n
d ≥ 200
n
b) Product groups for thermoplastics piping components as given in Table 10.
Table 10 — Product groups
Type group Thermoplastics piping components
1 Pipes
2 Bends and elbows
3 Branches
4 Other fittings
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 pipe or fitting design, (unless a member of the same product
range), 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 pipe and fitting
design, in the raw material or in the supplier of the components, or in the method of production (subject to the
definition of a family), which would affect significantly one or more of the characteristics.
This is not applicable for routine in-process adjustment and extension of the product range.
A change of supplier of a material or stabiliser does not lead to a change in performance if the chemical
composition remains the same.
Material modifications within the limits as given in the standards referenced in clause 2 are not considered as
a change of material.
Where components are used whose characteristics have already been determined, by the component
manufacturer, on the basis of assessment methods of other product standards, these characteristics need not
be re-assessed. The specifications of these components shall be documented.
Products bearing regulatory marking in accordance with appropriate harmonized European specifications may
be presumed to have the performances declared in the DoP, although this does not replace the responsibility
on the plastic pipe and fitting manufacturer to ensure that the plastic pipe or fitting as a whole is correctly
manufactured and its components have the declared performance values.
6.2.2 Test samples, testing and compliance criteria
The number of samples of plastics pipes or fittings to be tested/assessed shall be in accordance with Table 11
to Table 23.
Where the type testing is performed according to the relevant clauses of the applicable technical
specifications given in clause 2, the provisions of 6.2 are met.
