6.1 General
The technical details necessary for the implementation of the system of assessment and verification of
constancy of performance comprise provisions with regards to:
— the assessment of the performance of the construction product, which may be carried out on the
basis of testing (including sampling) of the product and
— the applicable factory production control.
6.2 Assessment of performance
6.2.1 General
When the intention is to declare any performance related to characteristics included in Annex ZA of this
standard this shall be carried out on the basis of testing (including sampling) of the product, in accordance
with Clause Characteristics'.
Assessment previously performed in accordance with the provisions of this standard, may be considered,
provided that this assessment was performed to the same or a more rigorous assessment 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.
For the purposes of assessment, the 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 characteristic for all products within that same family.

---------------------- Page: 9 ----------------------
oSIST prEN 14891:2020
prEN 14891:2020 (E)
In addition, the determination of the product performance shall be:
— carried out for all characteristics included in the standard for which it is intended to declare the
performance
— on first application of this standard, or
— at the beginning of the production of a new or modified liquid-applied water impermeable
product, unless a member of the same product family, or
— at the beginning of a new or modified method of production, where the modification may affect
the stated properties;
— repeated for the characteristic(s) in question, whenever a change occurs in the liquid-applied water
impermeable product design, in the raw material(s) or in the supplier of the components, and/or in
the method of production (subject to the definition of a family), which may affect significantly the
performance in relation to one or more of the characteristics.
Where components are used whose performance in relation to their characteristics has already been
determined on the basis of assessment methods of other harmonized technical specifications and those
components bear CE marking in accordance with those harmonized technical specifications, these
performances do not need to be re-assessed, if the intended use and the assessment methods of this
standard correspond to previously used. The specifications of these components shall be documented.
6.2.2 Test samples, testing and compliance criteria

6.3 Verification of constancy of performance
6.3.1 Factory Production Control (FPC)
6.3.1.1 General
An FPC system shall be established, documented, operated and maintained to ensure that the products
placed on the market comply with the declared performance in relation to 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 and provisions shall be documented in a systematic manner in the form of written
policies and procedures.
The responsibility, authority and the relationship between personnel that manages, performs or verifies
work affecting constancy of the performance of the product, shall be defined.
The qualification and competence (e.g. on the basis of education, training, skills, or experience) of
personnel performing tasks affecting the assessment and verification of constancy of performance of the
product shall be recorded.
Documents defining the factory production control system shall be drawn up and kept up- to-date.
Documentation and procedures should be appropriate to the product and production process. The FPC
system should achieve an appropriate level of confidence in the constancy of performance of the product.
This involves:
a) the preparation of documented procedures and instructions relating to factory production control
operations, in accordance with the technical specification to which reference is made;
b) the effective implementation of these procedures and instructions;
c) the recording of these operations and their results;
d) the use of these results to correct any deviations, correct the effects of such deviations, treat any
resulting instances of non-constancy and, if necessary, revise the FPC system to rectify the cause of
non-constancy of performance.
6.3.1.2 Equipment
6.3.1.2.1 Testing
All weighing, measuring and testing equipment shall be checked, calibrated and regularly inspected
according to documented procedures, frequencies and criteria.
6.3.1.2.2 Production
All equipment used in the production process shall be regularly inspected and maintained to ensure use,
wear or failure does not cause inconsistency in the production process. Inspections and maintenance
shall be carried out and recorded in accordance with written procedures and the records retained for the
period defined in the FPC procedures.
6.3.1.3 Raw materials and components
The specifications of all incoming raw materials and components shall be documented, as shall the
inspection scheme for ensuring their compliance.
