Ships and marine technology - Small weathertight steel hatches (ISO 5778:1998)
This International Standard specifies the main dimensions, location and number of fittings, materials and quality of manufacture for small weathertight steel hatches for application on board ships in order to ensure interchangeability of the hatches. The remaining dimensions are left to the manufacturer. The hatches are suitable for loading operations and for giving access to storage compartments and dry cargo holds.
The hatches are not suitable as an access to any kind of tanks and shall not be used as escape hatches.
These hatches generally conform to the requirements of the International Convention on Load Lines 1966 (LLC66). The possibility for application in position 1 and position 2 has to be considered for each situation and, where necessary, the hatch covers shall be provided with additional stiffening.
NOTE — Users of this International Standard should note that while observing the requirements of this standard, they should, at the same time, ensure compliance with such statutory requirements, rules and regulations as may be applicable to the individual ship concerned.

The work of preparing International Standards is normally carried out through ISO technicalcommittees. Each member body interested in a subject for which a technical committee has been established hasthe right to be represented on that committee. International organizations, governmental and non-governmental, inliaison with ISO, also take part in the work. ISO collaborates closely with the International ElectrotechnicalCommission (IEC) on all matters of electrotechnical standardization.Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.International Standard ISO 5778 was prepared by Technical Committee ISO/TC 8, Ships and marine technology,Subcommittee SC 8, Structures.This second edition cancels and replaces the first edition (ISO 5778:1979), of which it constitutes a technical revision.AmendmentsThe following amendments have been made to the first edition (1979-12-15).a) The nominal size 830 × 630 has been added.b) The inclined and vertical position of the hatch-seal retaining bar has been admitted.c) The tolerances for a, b, a1 and b2 have been added in tables 2 and 3.d) The text of 3.4.2 has been supplemented.e) The distance between the hinge's pivot and the coaming has been changed from 55 mm to 60 mm.f) The minimum tensile strength of the steel for coamings, cover plates, hinges, etc. has been changed to340 N/mm2.g) The designation has been added.h) The standard has been editorially revised.SIST EN ISO 5778:2000
