8、9 National foreword This British Standard has been prepared under the direction of the General Mechanical Engineering Standards Policy Committee. It is identical with ISO 5797-1:1989 “Shipbuilding and marine structures Windows and side scuttles for fire-resistant constructions Specifications Part 1:
9、 “B” class divisions”, published by the International Organization for Standardization (ISO). The Technical Committee has reviewed the provisions of ISO 1751:1977, ISO 3254:1975, ISO 3903:1977, ISO 5779:1987 and ISO 5780:1987, to which reference is made in the text, and has decided that they are acc
10、eptable for use in conjunction with this standard. A related British Standard to ISO 1751:1977 and ISO 5780:1987 is BS MA 24:1974. A related British Standard to ISO 5779:1987 is BS MA 25:1973.
