6 Evaluation of conformity
6.1 General
The compliance of pipes and fittings to 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 Initial Type Testing – Type Testing
6.2.1 General
Initial Type Testing and Type Testing shall be performed to demonstrate compliance with this European
standard.
All essential characteristics for which the manufacturer declares performances, are subject to Initial Type
Testing. In addition, the need to perform Type Tests applies to all other characteristics included in a standard
when the manufacturer claims compliance, unless the standard gives provisions (e.g. use of previously
existing data, CWFT and conventionally accepted performance) for declaring performances without
performing tests.
For the purposes of testing, 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 1 Products may be in different families for different characteristics.
For type testing the following family groups apply:
a) Size groups for pipes and fittings as given in Table 1.
prEN 15014:2011 (E)

NOTE 2 Size groups and product groups are not applicable for glass-reinforced thermosetting piping components
In addition, Type Tests or Initial Type Testing 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;
 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 production process (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 (see Table 3).
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 certain limits are not considered as a change of material. Guidance for these
limits can be found in the standards given in Annex B.
Tests previously performed in accordance with the provisions of this standard, respectively standards as listed
in Annex A, may be taken into account provided that they were made to the same or a more rigorous test
method, under the same system of attestation of conformity on the same product or products of similar design,
construction and functionality, such that the results are applicable to the product in question.
Products marked in accordance with appropriate harmonised European specifications may be presumed to
have the performances stated with that marking, although this does not replace the responsibility on the
prEN 15014:2011 (E)
plastic pipe and fitting designer to ensure that the plastic piping system as a whole is correctly designed and
its components products have the necessary performance values to meet the design.
6.2.2 Test samples, testing and compliance criteria
The initial type testing of the characteristics according to Clause 4 shall be performed in accordance with the
sampling procedure given under type tests (TT) of the applicable product specific standards for assessment of
conformity as given in Annex B. If the standard does not contain one or more of the characteristics, then
testing as given in Table 3 shall apply.
For products where no such standard exists Table 3 shall apply.

6.2.3 Test reports
All Type Tests, and/or Initial Type Tests and their results shall be documented in test reports.
prEN 15014:2011 (E)
All test reports shall be retained by the manufacturer for at least 10 years after the last date of production of
the pipes and fittings to which they relate.
6.3 Factory production control (FPC)
6.3.1 General
The manufacturer shall establish, document and maintain an FPC system to ensure that the products placed
on the market comply with the declared performance of the 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 production control system documentation shall ensure a common understanding of conformity evaluation
and enable the achievement of the required product characteristics 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 this European standard.
