The NTN 167:2014 has been replaced by NTN 167-L:2017.

This new version provides further clarifications on the requirements for automatic smoke detectors, but now also covers automatic carbon monoxide detectors and heat detectors in order for them to be BOSEC-certified.

This revised technical note is already in force.

The NTN 167-L new version is available in English, French and Dutch in a paper or PDF form.
