Ventilation grilles - combining

I wonder if there's anyone who agrees that there are too many classes containing term grille under group EG015240 and would like to work with me regarding combining those into one class utilizing existing features and values. Eg EC010347 and EC010348 are ones (but not limited) that I've been thinking.

Jari, Best is to contact ETIM Finland, where you can volunteer to start this working group locally. You could also ask to be representing or assisting them in the Sector Committee HVAC and Plumbing. International working groups are formed within Sector Committee Meetings. You can always send in your own proposals at your national ETIM office.

Jeroen, I have to admit I'm somewhat skeptic with the approach you mentioned due to the fact that my idea goes pretty far. Eg we have louvers that are basically for outside use and grilles for various purposes and form. And in our primary local market louvers mainly focus on rain and snow where there're areas in the world that has sand as a challenge. Therefore I'd like to have ideas from totally different markets as well.
