Testing centre for wood-fired heating systems
Through its activities, the accredited testing centre supports the safe, clean and efficient operation of boilers and domestic heating systems.
The testing centre for wood-burning stoves is accredited as a type C laboratory by the Swiss Accreditation Service SAS. A type C laboratory is authorised to develop and validate its own test procedures and have these procedures accredited and can therefore respond much more flexibly to the specific needs of customers.
The accreditation therefore applies to the test types and measurement principles on which the test methods are based, such as the following:
Heating tests
Testing at nominal heat output
Testing at low / light load
Determination of direct and indirect efficiency
Baking and cooking tests
Carrying out safety tests
Testing of limiting devices
Checking the design of the safety heat exchanger
Checking the fire protection requirements
Design criteria for solutions to prevent burn-back
Leakage, pressure loss and pressure loss testing
Carrying out leak tests
Pressure testing of water-bearing components
Leak test on the heating gas side
Water-side resistance
Analysing fuel properties and determining the water content
Analysing gaseous flue gas components
Oxygen (O2)
Carbon monoxide (CO)
Carbon dioxide (CO2)
Hydrocarbons (VOC)
Nitrogen monoxide and dioxide (NO, NO2)
Method for particle measurement (PM)
Determination of the dust mass concentration at low dust concentrations
Calculations
Annual space heating utilisation rate
Energy efficiency index
Annual space heating emissions
Calorific value (GCV)
Checking the requirements for design, production, safety and technical heating requirements
Checking the risk analysis for completeness, correctness and plausibility
Electrical power consumption of heat generators
Test procedure for airborne noise emissions from heat generators
Determination of the effectiveness of downstream
Dust reduction devices
The following product groups can thus be tested with suitable test methods within the scope of accreditation:
- Domestic fireplaces for solid fuels
- Room heaters EN 16510-2-1, EN 12809 (*)
- Fireplace inserts including open fires EN 16510-2-2, EN 13240 (*)
- Cookers EN 16510-2-3, EN 13229 (*)
- Domestic boilers (up to 50 kW) EN 16510-2-4, EN 12815 (*)
- Storage heaters EN 16510-2-5, EN 15250 (*)
- Room heaters, inserts and cookers for wood pellets EN 16510-2-6, EN 14785 (*)
- Boilers for solid fuels ≤ 500 kW, type testing (EN-303-5)
- Solid fuel boilers > 500 kW, safety test (own test method based on EN-303-5)
- Solid fuel boilers > 500 kW to ≤ 1,000 kW, type test (own test method based on EN-303-5)
* For these test methods, the test centre is recognised as a designated body (Notified Body, conformity assessment body) NB 2113 in accordance with European Construction Products Regulation No. 305/2011. These have been withdrawn and will be replaced by the new 16510-2 series of standards as soon as the latter have been harmonised by the European Commission.
Emissions are assessed in accordance with the regulations of the European Ecodesign Directive.
The test centre is registered with the Swiss Accreditation Body under the accreditation number STS 0396. It is also recognised by the EU Commission as designated body (Notified Body, Conformity Assessment Body) NB 2113 in accordance with the European Construction Products Regulation No. 305/2011. This guarantees EU-wide recognition of the reports issued by the test centre. We also advise national authorities on the drafting of new legislation and chair the standards committee INB NK-176 - Combustion systems for solid and liquid fuels.
