Environmental Project No. 1139 – Comparison of measurering results between solid fuel stoves tested in accordance with EN 13240 and NS 3058

Comparison of measuring results between solid fuel stoves tested in accordance with EN 13240 and NS 3058

7. Conclusion

It must be concluded that it is not possible on the basis of this report to make clear parallels between CO values achieved during EN testing and values for particle emission obtained during NS testing. Therefore, as a matter of course it will not be possible on the existing basis to substitute requirements on particle emission with requirements on the CO value.

The reason for the absence of the expected connection between the EN test’s CO value and the NS test’s particle emission is probably due to different test conditions during the two tests and the fact that the CO emission and the particle emission during a test course do not necessarily take place simultaneously (please refer to a more detailed description of these differences under paragraph 2 – formulation of the assignment).

To eliminate these elements it would be necessary to combine the two test methods and register all desired parameters in an overall test course.
