ISO/TC 188/WG 20 - Windows, portlights, hatches, deadlights and doors

This document specifies technical requirements and test methods for windows, portlights, hatches, deadlights and doors on small craft with a length of hull, LH, as defined in ISO 8666:2016, of up to 24 m. It takes into account the type of craft, its design category, and the location of the appliance. The appliances considered in this document are only those that are critical for the craft's watertightness. Openings and non-opening devices fitted below area I (see 3.5.2) are excluded from the scope of this document.

This International Standard specifies technical requirements for windows, portlights, hatches, deadlights and doors on small craft of hull length up to 24 m, taking into account the type of craft, its design category, and the location of the appliance. The appliances considered in this International Standard are only those that are critical for the craft's watertightness, i.e. those that could lead to flooding in case of rupture of the plate. This International Standard is mostly intended to be used for recreational craft, but it may be used for non-recrational small craft of hull length up to 24 m, excluding lifeboats. However, it is not applicable to commercial or work boats used in severe conditions.
