We have an interesting question on our intranet electrical forum related to a fill chart for conductors listed in mm's. I believe there is a IEE standard that may show one, but I am not familiar with it.
Does anyone such a chart as a published standard?
Thanks

is this what your looking for.

Thanks jlhmaint, that is just what I am looking for.

I can scan/e-mail the U.K. IEE conduit fill tables, if that would be of any additional help.
