Successful notification according to EN 16510

We were one of the first European laboratories to receive notification in relation to the new EN 16510 series of standards. The notification certificate was sent to us by the Deutsches Institut für Bautechnik, which means that we are now authorized to issue test reports in accordance with EN 16510.

The notification concerns the following construction products:

EN 16510-2-1Roomheaters
EN 16510-2-2inset appliances including open fires
EN 16510-2-3Cookers
EN 16510-2-6 Mechanically by wood pellets fed roomheaters, inset appliances and cookers

The notified bodies have submitted a draft on the use of historical data related to part 2-1 (room heaters) to the European Commission. The decision will be communicated within the next 14 days.
The proposal for the use of historical data for the other parts of the standard EN 16510 2-2 to 2-6 will be processed by the notified bodies in the coming week.

The EN 16510 series of standards replaces the standards EN 13240, EN 13229, EN 12815, EN 12809, EN 14785 and thus the majority of standards for small fireplaces. From 09.11.2025, the fireplaces concerned must be placed on the market with a test report in accordance with the corresponding part of EN 16510. The standard for storage fireplaces EN 15250 will be harmonized at a later date and is not yet acutely affected.

Further information on EN 16510 can be found here: Harmonization of EN 16510 – RRF (

You are welcome to contact us about tests in accordance with EN 16510 or the use of historical data from your fireplaces.

Harmonization of EN 16510

Today we can inform you that the long-awaited citation in the Official Journal of the European Union of the designated parts of the EN 16510 series of standards, and thus harmonisation, has finally taken place.

This concerns the following parts of the standard

EN 16510-2-1:2022     Residential solid fuel burning appliances – Part 2-1: Room heaters.

EN 16510-2-2:2022     Residential solid fuel burning appliances – Part 2-2: Inset appliances including open fires

EN 16510-2-3:2022     Residential solid fuel burning appliances – Part 2-3: Cookers

EN 16510-2-4:2022     Residential solid fuel burning appliances – Part 2-4: Independent boilers – Nominal heat input not exceeding 50 kW

EN 16510-2-6:2022     Residential solid fuel burning appliances – Part 2-6: Mechanically by wood pellets fed heaters, inset appliances and cookers.

The coexistence period (transition period) has been set at 24 months (until 9 November 2025) by the European Commission. During this time the products named above can still be on the market based on the original test reports.

What will come next?

Now, after the standard has been harmonized, can we apply for notification to the DIBt. As soon as the notification has been issued by the DIBt, the testing laboratories are allowed to issue test reports in accordance with the above-mentioned standards.

From November 9, 2025, the above-mentioned construction products must be declared with a CE marking based on type tests in accordance with the applicable part of EN 16510.

We are currently still waiting for information on how to deal with historical data from existing test reports. The committee of the notified bodies SG03WG2, in which we participate, made a proposal here. However, there is no official decision of the european commission yet.

You are welcome to contact us about tests according to EN 16510 or the transfer of historical data.

The new standard series EN 16510-x:2022

10 years ago, the revision of the old standards for residential solid fuel burning appliances were decided.

Due to administrative barriers and legal requirements for harmonized standards according to the Construction Products Regulation the release has been continually delayed. The new standards should reflect the state of art and replace the following predecessor standards:

New Replaced 
EN 16510-1:2022General requirements and test methodsEN 16510-1:2018 aResidential solid fuel-burning appliances – Part 1: General requirements and test methods
EN 16510-2-1:2022RoomheatersEN 13240:2001Roomheaters fired by solid fuel – Requirements and test methods

a 16510-1:2018 was only used for measurements of PM, OGC, and NOx

b Part 2-5 has not yet been published

In addition to parts 2-1 to 2-6, the part 2-7: “Mechanically by wood pellets fed and wood logs roomheaters, inset appliances and cookers” is being worked on.

The standard series EN 16510-x residential solid fuel burning appliances consists of several parts. Part 1 specifies general requirements for appliances and the applicable test methods. Parts 2 describe device-specific requirements (essential and descriptive features) and define information for the performance declaration according to the European Construction Regulation. All Parts 2 are to be applied in connection with Part 1. Annex A (test methods) of Parts 2 must always be considered.

New requirements haven been established. It is now required to measure the emissions of the appliances and to determine the seasonal space heating energy efficiency as well as energy efficiency class. In addition, the emission limits for PM, NOx, OGC and CO have been adapted to the requirements of the Ecodesign Regulation (EU) 1185/2015. The emission limits for the seasonal space heating energy efficiency per type of appliance have also been adapted to the requirements of the Ecodesign Regulation (EU) 1185/2015. In the course of the safety test, additional distances compared to the predecessor standards must be measured. A risk assessment must be carried out for certain devices.

In emission tests for fireplaces fired by wood logs, three cycles must be considered for calculating the average emission, two of them must be consecutive. For all other fuels, two consecutive cycles must be considered to calculate the average emission in the course of the emission test.

To determine the efficiency of fireplaces fired by wood logs, three cycles must be considered for calculating the average, two of them must be consecutive. For all other fuels, two consecutive cycles must be considered for calculating the average in the course of efficiency tests.

With the harmonization of the standards series, the EN-PME method according to Annex F of EN 16510-1:2022 becomes mandatory for type testing. Furthermore, the content and requirements of Annex ZA change significantly, so the Declaration of Performance must be adjusted accordingly.

Use of historical data

The Sector Group SG03/WG2 of designated test laboratories for roomheaters for solid fuels discussed the application of the new standards and further use of test results from previous tests (historical data). This was presented using EN 13240 and EN 16510-2-1. A common position shall be published as an approved guide by GNB-CPR. The development of separate documents as position papers of SG03/WG2 for the use of historical data for other parts such as EN 14785 and EN 16510-2-6 will follow later.

The final evaluation of whether historical data from an existing type test report can be adopted will be made individually by the notified bodies. After approval of the guideline, we will publish details on the evaluation and use of historical data.

Due to the high demand and the high administrative effort, we recommend conducting new tests now and reviewing your test reports early.

RRF tests the new certification program of the HKI

In cooperation with the certification body of the TÜV Süd, the HKI has published a new certification program for fireplaces in accordance with EN 13229, 13240 and 15250. Manufacturers of efficient and low-emission stoves and other fireplaces can now have this certified. As an approved laboratory, the RRF also performs tests in accordance with this certification program.

The basics for the certification of your fireplace are as follows:

  1. You submit the certification application (application for certification of local space heaters for wood logs) to the certification body. We are happy to help you with the application.
  2. If your application and application documents have been checked completely and positively, you will receive a draft of the certification contract from the certification body.
  3. After the certification contract has been concluded, the certificate for the use of the certification mark is issued based on our type test and the test report.
  4. To maintain the certification, manufacturers must have a regular (at least once a year) product-related control test – usually in the manufacturers works. This ensures that the fireplaces manufactured in ongoing production correspond to the certified prototype. Since we are a recognized monitoring body, we can register our auditors with the certification body accordingly to your wishes.
  5. The validity of the certification depends on the testing and certification regulations of the certification body. Should the state of the art and / or the legal regulations change, the certification program may adapt.

We would like to assist you as your partner in testing, certification and monitoring of your fireplace and please do not hesitate to contact us for questions about the topic, to make appointments or to select a suitable auditor.

Requirements of the Eco-Design Regulation in 2022

With this year, the implementation for the requirements of the Eco-Design Regulation (EU) 2015/1185 in 2022 is getting closer and closer. At the turn of the year, the meeting of the German technical heads of laboratories took place. There, the implementation of Eco-Design requirements in practice with regards to the test reports and the manufacturers documents were clarified between industry, German standardization bodies and German notified bodies. 

At this meeting, it was discussed, which documents apply. It should be noted that many manufacturers only pay attention to average values shown in the test reports and compare them with the Eco-Design requirements. However, in addition, further requirements must be met. These emerge both from the regulation itself and from an associated official journal of the European Commission (see below).

What is the legal bases?

  • The general requirements and value limits are specified in the Eco-Design Regulation (EU) 2015/1185. In addition, the Official Journal of the European Commission “2017/C 076/02” applies.


Many manufacturers only pay attention to the average values ​​shown in test reports and compare them with the eco-design requirements. In addition, there are further requirements mentioned in the Official Journal “2017/C 076/02” need to be met!

So that no invalid declarations are created, we would like to give you specific information on how to meet the requirements:

  • The declaration is made by the manufacturer, not by the test laboratory.
  • Currently, the declaration is made by the manufacturer in the technical documentation listed in the regulation, not in the declaration of performance according CE marking.
  • A test report of the current EN standards (EN 13240, 13229, 14785, 12815, 15250, etc.) is not sufficient for the declaration.
  • CO, NOx and OGC content must have been determined in accordance with EN 16510-1.
  • This also applies to the heat output and efficiency (with the exception of EN 14785 and EN 15250).
  • The dust content must have been determined in accordance with CEN/TS 15833 or EN 16510-1.
  • If the manufacturer requests confirmation from the test laboratory, this must not appear as a notified body in the document (the Notified Body Number is not mentioned).
  • If the manufacturer declares compliance with Eco-Design, he bears the sole responsibility.

What does this mean in practice?

  • Confirmation letters from test laboratories, such as certificates, lists, letters of confirmation, in which the test laboratory appears as a notified body – as they are currently published by some manufacturers are for marketing purposes – may not serve as a base for the declaration.
  • The measurements of the above-mentioned parameters must have been performed in accordance with EN 16510-1. This applies to new test as well as performance tests. The requirements of EN 16510-1 are, for example:
    • At least 2 continuous burning cycles in a row
    • For EN 13229 fireplaces 3 burning cycles instead of 2
    • Different minimum burning cycle times
  • The fuels used in the test must correspond to the fuel specification of EN 16510-1. This also applies to new test as well as performed tests.
  • If the manufacturer wants to know whether his test report, for example according to EN 13240, is compliant to the above-mentioned requirements, the test laboratory carry out an evaluation of the raw data if necessary. An alternative is that the measurement method EN 16510-1 is listed for the corresponding parameters in the current test reports.
  • The manufacturer can also declare compliance with the Eco-Design requirements based on their own measurements and calculations. Based on this, however, no official confirmation / certificate can be created by our laboratory.

What kind of support does the RRF offer you:

  • Issue of certificates for publication
  • If necessary: re-evaluation of raw data or re-examination of the missing parameters on the test bench
  • Issue of letters of confirmation of the fulfilment of the requirements for internal use

If you have OEM products in your portfolio, you should have the test report, which serves as the basis, checked by the owner of the original test report.

We are happy to offer you the opportunity to discuss further details on this topic in a personal meeting. If you send us a list of your fireplaces / test reports, we can make you an offer for the evaluation effort and the above-mentioned services for you.

First exchange of experiences on the Blue Angel

The environmental label “Blue Angel” started the certification of roomheaters this year. At the end of the year there was a call to share experiences. The test laboratories were asked to share their experiences from the first measurements in order to optimize the measurement method and the test procedure and to clarify detailed questions.

Of course, the RRF also took part and was able to contribute some important experience from the tests carried out.

Participation in standardization committees

Even during the corona pandemic, standardization work does not stand still. Therefore, the RRF is still active in the standardization committees like currently for the topic of exhaust systems (TC 166) and takes part in the web meetings on your behalf.

Passing of the “Blauer Engel”

In its meeting on 11. and 12. December 2019 the “Jury Umweltzeichen” did pass the “Blauer Engel” for wood burning stoves. This means that the environmental label can be applied for at the RAL gGmbH from 01. January 2020.

The awarding criteria and all necessary application documents are now available in German language on the “Blauer Engel” website:

The corresponding documents in English language will follow shortly.

Since the RRF was, of course; also actively involved in the development of the criteria of the environmental label, we have included the test in our portfolio and can offer you this test for your fireplaces. In the course of this, we have invested in the measuring device for particle counting, so that we can offer you the required particle counting method from January.

You are welcome to contact us for any questions or a non-binding offer request.

Participation in the expert workshops and expert discussions on the topics of the environmental label “Blauer Engel” and evaluation of the 1. BImSchV

Due to our competence, we are regularly invited to expert rounds.

We are glad to take this responsible part to actively participate in the legislation, climate protection and the future of the industry.  

1. BImSchV

In the second expert discussion, on 12 September 2019 in Berlin, regarding the evaluation of the 1. BImSchV, the preliminary final report of the DBFZ (Deutsches Biomasse Forschungszentrum) was presented and discussed.

Christian Droll actively participated in the discussion.

The amendment of the 1. BImSchV 2010 revised the regulations for solid fuel appliances and was complemented with new requirements. On one hand, the emission limits for new appliances were significantly tightened and, on the other hand, for the first time, new limits were established for existing appliances in the retail sector – with transitional periods – connected with retrofitting or shut down responsibilities.

Eight years later, the question now arises as to whether the amendment to the 1. BImSchV actually achieves the hoped-for and also assumed in individual studies on future emission trends and whether there is still room for improvement if necessary.

The final report should answer this question and provide a basis for discussion for a renewed amendment of the 1. BImSchV.

In further expert rounds we will accompany the revision of the amendment.

Blauer Engel

Since the beginning of the expert discussions on the environmental label “Blauer Engel”, the RRF participated in the relevant meetings. We will include the test program in our portfolio and are already offering preliminary tests on the current version of the “Blauer Engel” criteria.

The criteria of the “Blauer Engel” was lastly discussed at the second Environmental Label Hearing “Kaminöfen” (DE-UZ xxx) on 18./19.09.2019 in Berlin at the Federal Environment Agency (Umweltbundesamt). Representing the RRF, Christian Droll participated and integrated our position into the meeting. On 11 and 12 December 2019 the the “Blauer Engel” will be presented to the jury “Umweltzeichen”. Until the 22 November comments can be send to the RAL non-profit GmbH, which will be awarding the label.

The final result of the decision will be made by the jury in December and the label will be introduced from the 01 January 2020 on out. The awarding criteria can be requested at or

Future Workshop

In addition, in June 2019, the first Future Workshop for the fireplaces and chimney industry took place at the Umweltforschungszentrum (UFZ) in Leipzig, in close proximity to the Deutschen Biomasseforschungszentrum (DBFZ). The Europäische Feuerstätten Arbeitsgemeinschaft (EFA), the Zentralverband Sanitär, Heizung, Klima (ZVSHK) und der Fachverband Schornsteintechnik invited to this event. Over two days, the innovative workshop concept identified the industry’s current challenges and planned future steps. What was special: Not only the industry was involved, also representatives of other interested parties and politics came to Leipzig.

On 15 – 16 January, the Future Workshop will be continued at the Agritechnical in Hanover, in order to substantiate the results of the first workshop.

Publication of EN 16510-1 as a non-harmonized standard

With the issuing date from July 2018, the English version of EN 16510-1 has been published in CEN. The German version will now follow in the next few weeks and thus the revision of the old fireplace standards is slowly taking shape.

A new structured setup of the EN 16510 series of standards is intended to simplify the handling for both manufacturers and users. Part 1, which is now published, contains the general requirements and tests for all domestic solid fuel fireplaces and is to be used in future in conjunction with a specific Part 2 for the corresponding type of fireplace.

Since this is a non-harmonized standard, it does not yet replace the current harmonized standards such as B. EN 13240, 13229, etc.

In EN 16510-1 the emission measurement methods for NOx, OGC and PM (Annexes D, E and F of the standard) are specified in a more detailed way than the previous specification and the test procedure for the type test is specified more clearly than in the previous CEN / TR 15883, which will be replaced by EN 16510-1. Due to the relevance of these detailed descriptions of emission measurement methods, CEN / TC 295 decided in November 2016 to publish Part 16510-1 as a non-harmonized standard. In addition, manufacturers can already apply the EN 16510-1 for the type testing of new developments, in order to avoid inspections after the harmonization of parts 2. There are no contradictions to the currently harmonized old standards.

However, it will not be possible to simply rewrite the test reports because EN 16510-1 and the specific parts 2 make further administrative requirements. Consequently, when converting the test reports to the 16510 series of standards, after the complete harmonization, an increased effort for the issuing of the test reports must be expected.
