BS ISO 1751:2012 pdf download – Ships and marine technology — Ships’ side scuttles
This International Standard specifes the classifcation 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.

3 Terms and defnitions
For the purposes of this document, the terms and defnitions given in ISO 6345 and ISO 21005 apply.
Side scuttles shall be classified by series, types, models and nominal sizes in accordance with 4.1 to 4.4,respectively.
NOTEA survey of standardized side scuttles is given in 4.5 and Table 3.
Further classification characteristics are the material classes; see 6.2 and Table 10.4.1Series
4.1.1 Regular series (N)
Side scuttles of the regular series shall contain a thermally toughened safety glass pane that meets therequirements of IsO 21005.
Side scuttles of the fire-resistant series shall be provided for installation in “”A” or “B” class divisions. These sidescuttles shall contain glass panes that meet the requirements of ISO 5797.
Modifications to the construction and installation of the glassholder and main frame, as well as additionaltesting and marking, shall be in accordance with ISO 5797.
Ships” side scuttles may be of three types:
– Type A: Heavy-type side scuttle;
– Type B: Medium-type side scuttle;
– Type C: Light-type side scuttle.4.3Models
Models shall be designated in accordance with the following principal characteristics:-opening or non-opening model;
with or without deadlight;
opening direction of glassholder;-type of fastening.
The various combinations of these, which are in accordance with the definitions in lSO 6345, are given in Table 1.
The nominal size is defined by the clear light diameter d:of the side scuttle; see Table 2.
4.5 Survey of types, models and sizes
A survey is given in Table 3 for all side scuttles standardized in this International Standard. It applies to series N (regular) and series P (fre-resistant) side scuttles.
The illustrations given in Table 3 do not defne the construction; they are simplifed examples for information only.
5 Technical requirements
Side scuttles of all series, types, models and nominal sizes shall be manufactured to the requirements (dimensions, materials, etc.) given in this International Standard. They shall be capable of meeting the test requirements specifed in Clause 7.
