This International Standard specifies the classification of side scuttles for ships (series, types and models), and gives the dimensions for interchangeability and construction, materials, tests, marking and designation of these framed side scuttles with thermally toughened safety glass panes. NOTE This International Standard is based on the experience of side scuttles and glass manufacturers, shipbuilders and authorities who apply to ships the Regulations of the International Convention for the Safety of Life at Sea, 1974 (SOLAS 1974), as amended, 1981, and of the International Convention of Load Lines, 1966, as amended.
