Testing for UV Light filtering

I am trying to locate a consulting firm, or the equipment
needed, to test the ultraviolet filtering of windows and_
skylights in the new addition to the UC San Diego, Central
University Library.  I have a Crawford UV Monitor Type 760,
but need to take more exact measurements to verify that the
windows are filtering 90% of the UV as claimed by the
manufacturer.
Thank you!
