5.1.2 Range of operation
5.1.2.1 Type approval tests and conversion of test data shall be undertaken using methods defined in
EN ISO 9906:2012 Grade 2 and the tolerances given there.
Where there are a range of impeller diameters, tests shall include the maximum and minimum impeller
diameters. Performance between tested impeller diameters may be interpolated in accordance with
EN ISO 9906:2012, Annex B for changes not exceeding ± 4 % in impeller diameter.
The test data required for the purpose of evaluation in accordance with EN ISO 9906:2012, are
established at a minimum of 7 points uniformly distributed between the lowest rate of flow and the
highest rate of flow to be measured. The lowest rate of flow to be measured shall be between zero and
the minimum by-pass flow. NPSHR shall be determined for minimum and maximum impeller diameters
and speeds at 5 points between 0,3 Q and the highest flow, where Q is the rated flow. The highest flow
r r
to be measured shall be sufficient to demonstrate a non-overloading power characteristic or a flow
corresponding to at least NPSHR of 16m.
Pumps intended for use in High Hazard Process (HHP) or High Hazard Storage (HHP) pre-calculated
systems shall be tested to at least 140 % of the maximum demand flow where it shall be demonstrated
that the total differential head of the pump is at least 70 % of the total differential head at the design
flow. (Ref EN 12845:2015, 7.3.2, 10.7.2 and Figure 7). See also Figure B.1
Pump characteristic curve conversions for alternative drivers with differing speeds higher than the
minimum tested speed and lower than the maximum tested speed shall be converted using the formula:

6 Evaluation of conformity
6.1 General
The compliance of pumps 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
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, 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 under the responsibility of a notified
product certification body.

oSIST prEN 12259-12:2017
prEN 12259-12:2017 (E)
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 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 pump (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 pump
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.
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 pump manufacturer to ensure that the pump as a whole is correctly
manufactured and its component products have the declared performance values.
6.2.2 Test samples, testing and compliance criteria
The number of samples of pumps to be tested/assessed, the assessment methods and the acceptance
criteria shall be in accordance with Clause 5.
6.2.3 Test reports
The results of the determination of the product type shall be documented in test reports. All test reports
shall be retained by the manufacturer for at least 10 years after the last date of production of the pump
to which they relate.
6.2.4 Shared other party results
A manufacturer may use the results of the product type determination obtained by someone else (e.g.
by another manufacturer, as a common service to manufacturers, or by a product developer), to justify
his own declaration of performance regarding a product that is manufactured according to the same
design (e.g. dimensions) and with raw materials, constituents and manufacturing methods of the same
kind, provided that:
— the results are known to be valid for products with the same essential characteristics relevant for
the product performance;
— in addition to any information essential for confirming that the product has such same
performances related to specific essential characteristics, the other party who has carried out the
determination of the product type concerned or has had it carried out, has expressly accepted1 to
transmit to the manufacturer the results and the test report to be used for the latter’s product type
determination, as well as information regarding production facilities and the production control
process that can be taken into account for FPC;

— the manufacturer using other party results accepts to remain responsible for the product having
the declared performances and he also:
— ensures that the product has the same characteristics relevant for performance as the one that
has been subjected to the determination of the product type, and that there are no significant
differences with regard to production facilities and the production control process compared
to that used for the product that was subjected to the determination of the product type; and
— keeps available a copy of the determination of the product type report that also contains the
information needed for verifying that the product is manufactured according to the same
design and with raw materials, constituents and manufacturing methods of the same kind.
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 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.
In case the manufacturer has used shared product type results, the FPC shall also include the
appropriate documentation as foreseen in 6.2.4.
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 no
