Breakable Glass/Acrylic Standards needed

Hello Covers -
One of the items we manufacture is a 'breakable emergency panel' , about 6 inches square, and about 1/8" thick acrylic type "FF".
Because we make a large variety of these and new designs are always on the table, I have been looking for any standards or requirements, but have not found any. I know I can conduct some tests myself (and probably will), but does anyone know if there is some regulation out there? I thought there would have been something about this due to "manual call point" breakable fire enclosures, but I see nothing on it, and glass is not quite the same as acrylic.
