for modification of a window such as removing

it is shuttered with approved shutter ?

No.

Commentary

Wind pressure resistance, forced entry and air infiltration are also to be considered. Product components detailed on a product approval cannot be removed unless indicated in the approval’s limits of use, otherwise the product approval is not valid. Removal of a window’s sill for application as a pass through window requires testing of the unit without the sill. Note that exception #3 in the 2007 FBC section 2411.3.2 is only for the water infiltration test. If impact resistance is provided by use of shutters, then the balance of TAS202 testing requirements apply.
