basis of testing (including sampling), calculation or descriptive documentation 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) or calculation or tabulated
values, 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.
NOTE Products can be grouped into different families for different characteristics.
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 and for the attached documentation of the product:
— on first application of this standard, or
— at the beginning of the production of a new or 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;
— in case the list of characterization factors for the environmental assessment of products is revised.
— repeated for the characteristic(s) in question and for the attached documentation, whenever a
change occurs in the 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 or the attached
documentation;
— Where components are used whose performance in relation to their characteristics and attached
documentation 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 and attached documentation do not
need to be re-assessed, if the intended use and the assessment methods of this standard correspond
to those used in relation to the components. The specifications of these components shall be
documented.

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 FPC 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.
It shall be verified that the product maintains the declared performances also after de-coiling,
straightening, cutting and bending.
6.3.1.3 Raw materials and components
As per the FPC checks related to chemical composition, the following shall be checked:
— verification of the chemical composition of the product according to the specifications of the
manufacturer;
— verification of the consistency of the chemical composition with the relevant information provided
as regards welding of the material.
As per the FPC checks related to de-coiling, the following shall be checked:
— verification that the products maintain the declared performances after de-coiling, straightening,
cutting and bending.
As per the FPC checks related to the release of dangerous substances of the coating, the following shall
be checked:
— temporary protective measures;
— corrosion prevention coatings;
— fire performance coatings;
— coatings for other purposes.
As per the FPC checks related to the fire characteristics of the coating, the following shall be checked:
— density or weight applied / quantity per unit area;
— organic content of the coating;
— flame retardant content of the coating;
— verification of the fire performance of the coated product.
6.3.1.4 Traceability and marking
Individual products, product batches or packages shall be identifiable and traceable with regard to their
place of their production.
Written procedures ensuring that processes related to affixing traceability codes and/or markings are
inspected regularly shall be maintained.
6.3.1.5 Product assessment and evaluation
Procedures to ensure that the performance in relation to the declared characteristics are maintained shall
be established. The characteristics, and the means of control, shall be as in Table 10.
