boiler or heat exchanger (integral part of the appliance containing water to be heated up) for the supply
of hot water for central heating systems.
These slow heat release appliances may be supplied either as an assembled appliance or as a pre-
designed unit consisting of prefabricated components designed to be built on site in accordance with the-
specified assembly instructions.
These appliances can burn one or more types of the following solid fuels as specified:
— wood logs;
— compressed untreated wood;
— wood pellets;
— lignite briquettes;
— solid mineral fuels;
— peat briquettes.
This document is not applicable to:
— mechanically fed appliances
— appliances with fan assisted combustion air
— one off installations
This document specifies procedures for assessment and verification of constancy of performance (AVCP)
of characteristics of solid fuel burning slow heat release appliances.

6 Assessment and verification of constancy of performance – AVCP
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 residential solid fuel burning appliance, which may be
carried out on the basis of testing (including sampling), calculation, tabulated values 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), calculation, tabulated
values or descriptive documentation of the product, in accordance with clause 'characteristics'.
Assessment previously performed in accordance with the provisions of this document, may be
considered provided that this assessment was made 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 (see Annex G and EN 16510-1:2022,
Annex G).
Products may be grouped into different families for different characteristics.
In addition, the determination of the product type 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 residential solid fuel burning appliance,
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 residential solid fuel
burning appliance 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 kit 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
