Question
Which is the suitable classification for clean rooms in hospitals? Is there any classification that gives the category of ISO for rooms such as "operating theatres", "isolation room", "intensive care room", etc?

Answer

France requires that an operating theatre meet at least an ISO 14644-1 Grade 5 at 0.5 um prior to being used. I am unaware of any other guidance value for hospitals in Europe.
