pre-designed unit consisting of prefabricated components designed to be built on site in accordance with
the manufacturer’s specified assembly instructions.
These appliances can burn the following solid fuels as specified:
— wood logs;
This document is not applicable to:
— appliances that are mechanically fed;
— appliances with fan assisted combustion air;
— single-firing heat storage sauna stoves, in which the stones are directly heated by the fire and the flue
gases, which pass through them;
— one off installations;
— appliances incorporating a boiler or connected to a water system.
This document specifies procedures for assessment and verification of constancy of performance (AVCP)
of characteristics of multi firing sauna stoves.

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 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 modifi
