Archive for category: Standardization and national requirements

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 16510-1:2022	General requirements and test methods	EN 16510-1:2018 a	Residential solid fuel-burning appliances – Part 1: General requirements and test methods
EN 16510-2-1:2022	Roomheaters	EN 13240:2001	Roomheaters fired by solid fuel – Requirements and test methods
EN 16510-2-2:2022	Inset appliances including open fireplaces	EN 13229:2001	Fireplace inserts including open fireplaces fired by solid fuel – Requirements and test methods
EN 16510-2-3:2022	Cookers	EN 12815:2001	Cookers fired by solid fuel – Requirements and test methods
EN 16510-2-4:2022	Independent boilers for solid fuels – Rated output up to 50 kW	EN 12809:2001	Boilers fired by solid fuel – Rated output up to 50 kW – Requirements and test methods
EN 16510-2-5:202x b	Slow heat release appliances fired by solid fuel	EN 15250:2007	Storage-fired appliances fired by solid fuel – Requirements and test methods
EN 16510-2-6:2022	Mechanically by wood pellets fed roomheaters, inset appliances and cookers	EN 14785:2006	Roomheaters for pellets firing – 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, NO_x, 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.

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.

ATTENTION

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.

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.

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 www.blauer-engel.de or www.umweltzeichen-ral.de.

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.

As of 07.11.2017, the new regulation n. 186, passed by the Minister of the environment, in collaboration with the Minister of health and the Minister of economy and development, came into force.

It applies to small fireplaces and boilers, which are operated with biomass solid fuels.

The regulation sets requirements for the emission of particles, OGC, NOx, CO and the efficiency.

There are 5 categories of emission requirements, which are divided into stars.

The requirements can be found in detail in the following table:

Type of fireplace	Particles (mg/Nm³)	OGC (mg/Nm³)	NOx (mg/Nm³)	CO (mg/Nm³)	N (%)

Boilers	60	30	200	500	80
Boilers fired by wood pellets	40	20	200	300	90
Every fireplace that does not reach the requirements for 2-Stars, will be categorized as 1-Star. The requirements mentioned in the table above are based on 13% O2.

The compliance of the value requirements needs to be proven by a document, the so-called “Certificato Ambientale”. The manufacturer can order this document, directly from us. We generally issue the “Certificato Ambientale” bilingually (English-Italian).

 

There is also a new requirement with regard to the state funding “Conto Termico 2.0”. Due to the fact that several contradictory documents have been submitted to the competent body, an official document of an accredited testing laboratory is required, which confirms compliance with the value requirements for “Conto Termico 2.0”. The manufacturer can also order this bilingual so-called “Rapporto Sintetico” (English-Italian), directly from us.

Of course, the RRF is an accredited laboratory for both the abovementioned Regulation as well as for “Conto Termico 2.0”. If you have any questions or interest, feel free to contact your personal contact or one of our employees.
