EN397 ('industrial') has a weak chinstrap to prevent injury if the helmet becomes trapped in machinery etc. and small vents to prevent items such as sparks hitting the wearer.
EN12492 ('mountaineering') has a strong chinstrap so the helmet stays in place in a fall – protecting the head, and large vents to help prevent workers getting too hot – an occupational health improvement.

The Duon has been successfully tested following accelerated UV exposure (the equivalent of 25 years in Northern Europe or 10 years anywhere in the world including Saudi Arabia). This was based on 40 hours per week average exposure. The Duon's maximum lifespan is now 10 years use.
