I have BT / Toyota technical data for there own overhead guard load test.

If I could have the rated capacity of this forklift in question I could post what test values BT / Toyota would use if it was one of there own machines & you could compare the standards.

Also if anyone has a link to the European standards id be grateful for a link.

Having twice seen the aftermath of a 1.1 ton pallets of stock land on top of a Reflex reach truck cab from nearly 11 meters up & a racking collapse that took several days to dig the truck out all I can say is both times the overhead guard saved the operators life.
