This International Standard provides requirements for windows and side scuttles for fire-resistant constructions for installation in “A” class and “B” class divisions as defined in FTP Code, Part 3 [(IMO Resolution A 754 (18)].

It lays down the requirements for the construction of glass panes and frames, as well as the testing and marking of such windows and side scuttles.

“B” class divisions are required only for inside installations.
