Amanda, I don't know the circumstances in which you are particularly interested but having been drawn into several disputes regarding RH in workplace environments, I have found that usually they are 'fine', i.e. within accepted limits. Often where there was a problem, it was related not to the moisture content of the air but to inadequate air movement and air changing. On one occasion I found that complaints of inadequate air quality was the verbalisation/manifestation of other problems of a more organisational nature. Have a Merry Christmas and a peaceful New Year.

I would have thought there is a British Standard, but having smurfed the net, I have not got anywhere so I thought I'd ask my learned colleagues! Many thanks for your help again Best wishes for the seasons festivity ! Amanda Dowson
