Overview

EN ISO 12216:2022 (identical to ISO 12216:2020) is a CEN-adopted international standard that specifies strength and watertightness requirements for windows, portlights, hatches, deadlights and doors on small craft with hull length (LH) up to 24 m (as defined in ISO 8666:2016). The standard covers technical requirements, test methods and assessment procedures for appliances that are critical to a craft’s watertight integrity and safety. It takes into account craft type, design category, and the location of the appliance; openings fitted below Area I are excluded.

Key topics and requirements

• Scope and definitions: Precise definitions of openings, plates, device types, and location areas (Area I, IIa, etc.).
• General requirements: Mandatory consideration of other applicable international standards and minimum requirements for strength and watertightness.
• Plate materials: Guidance and restrictions for materials such as acrylic sheet and glass, including special rules for laminated or high-impact-resistant glass.
• Fastening and end-connections: Requirements for plate end-connections, simply supported vs semi-fixed plates, glued plates, frames, fastenings and stiffeners.
• Watertightness tests: Minimum degree of watertightness and additional requirements for appliances affecting hull integrity; normative test methods are included (see Annex D).
• Strength assessment methods: Several options for verifying structural adequacy:
  • Direct calculation methods for monolithic plates (including selection of thickness, aspect-ratio coefficients, design pressure and safety factors)
  • Laminated glass calculation
  • Advanced calculation methods
  • Pressure test assessment method
• Annexes and tools: Normative and informative annexes cover unsupported plate dimensions (Annex C), test methods (Annex D), high-impact glass (Annex E), precalculated tables (Annex F) and location-area diagrams (Annex A).

Practical applications and users

This standard is essential for:

• Naval architects and boat designers specifying windows, hatches and doors to meet regulatory and safety requirements.
• Manufacturers of portlights, hatches and companionways ensuring product compliance and durability.
• Shipyards and fitters performing installations and repairs in accordance with accepted test methods and fastening rules.
• Classification societies, surveyors and regulators assessing conformity with CE/EU directives and national standards.
• Marine equipment testers performing strength and watertightness tests defined in the standard.

Using EN ISO 12216:2022 helps reduce water ingress risk, supports regulatory compliance across CEN member countries, and provides robust, harmonized procedures for design verification and type-testing.

Related standards

• ISO 8666 (small craft - principal data, including hull length LH)

5 Plate materials
5.1 General
Appliance plates shall be made of
— a transparent glazing material, such as polymethylmethacrylate (PMMA), polycarbonate (PC),
tempered glass, chemically reinforced glass or laminated glass, or
— a non-transparent plate material, such as plywood (PW), glass-fibre reinforced thermosetting
plastic (GRP), aluminium alloy, steel, etc.; or
— any other material of strength and stiffness or greater equivalent to those cited above.
5.2 Acrylic sheet materials
Polymethylmethacrylate (PMMA) made with a technique other than the casting procedure shall have
mechanical properties and resistance to ageing at least equal to those of cast PMMA.
5.3 Glass
5.3.1 Restrictions of usage
The use of glass is restricted as per 5.3.1.1 and 5.3.1.2 for use of simply supported plates, 6.3.1 for use in
area I and 6.3.2 for use in area IIa.
5.3.1.1 Monolithic glass
Monolithic glass shall only be made of thermally tempered glass, use of monolithic chemically reinforced
glass is not allowed.
5.3.1.2 Laminated glass
The glass plies used in laminated glass may be made of tempered glass (thermally or chemically
reinforced).
6 Specific requirements of appliances
6.1 Plate end connection and location
6.1.1 Simply supported plates
6.1.1.1 Plates in area I
Simply supported plates shall not be used in area I:
— on sailing monohulls in design categories A and B, and sailing multihulls in design category A;
ISO 12216:2020(E)
— on motor boats in design category A.
On other types of craft and design categories, simply supported plates may be used provided that all
the following conditions are met:
— the glazing material is PMMA or PC (see Clause 5);
— the plate thickness is equal to 1,3 times the one required by Clause 7;
— the fixing devices of the plate (hinge bolts, fixing knob, etc.) are not spaced more than 250 mm.
The above restrictions of use need not be considered if the appliance is equipped with a deadlight
meeting the requirements of 6.3.6.
6.1.1.2 Flexibly connected plates
Flexibly connected plates may only be used on motor boats of design categories C and D in areas III and
IV (see Figure B.3.)
6.1.2 Semi-fixed plates
6.1.2.1 Plates made of material other than glass
Semi-fixed plates may be used in boats of all design categories and in all location areas with the
restrictions of the special requirements given in 6.3.
This type of end connection can be achieved by one of the following means.
a) Connected with a counter frame: The edge fixity is achieved by pinching the plate at its periphery
between the boat shell or a frame and a counter frame. The counter frame shall be mechanically
fastened and/or glued to the structure of the boat.
b) Connected by gluing: The edge fixity is achieved by gluing the plate at its periphery to the boat
shell, to the structure of the boat or to a frame. This gluing can either be in a rabbet or a face, edge
gluing or any combination of these gluing methods.
c) Connected by direct fastening: The edge fixity is achieved by fastening the plate inside its periphery
to the shell, the structure of the boat or to a frame by correctly spaced and sized mechanical
fasteners. These fasteners may be bolts, rivets, self-tapping screws or any adequate mechanical
fasteners.
NOTE Even with the best fastening system, full edge fixity of a non-stiffened plate at its periphery can never
be achieved. Plates are therefore considered at best as semi-fixed.
6.1.2.2 Plates made of glass
There shall be no contact between metal and glass.
6.2 Fastening requirements
6.2.1 Fastening of plates and frames
Plates and frames can be fastened by mechanical means, glue or elastomer joints. All types of fastening
shall ensure watertightness of the plate or frame, and resistance to loads due to normal operating
pressure.
Every part of the mechanical elements connecting appliances to the rest of the craft shall be capable
of withstanding, without breaking, twice the force induced by the pressure loads defined in Clause 7.
This requirement shall be verified for inwards opening appliances, where hinges, locks, or any other
10 © ISO 2020 – All rights reserved

ISO 12216:2020(E)
part of the link chain between the plate and the support shall be checked by calculation or testing in
accordance with D.2.
6.2.2 Fastening of semi-fixed plates
Mechanical fasteners shall not induce parasitic stresses due to deflection or temperature changes, nor
stress concentration or stress raising.
For example, bolts in sharp angle counterbores and countersunk screw heads in conical bores shall not
be used.
Additional stresses brought by cold forming shall be considered when determining the plate scantlings
in Clause 7.
6.2.3 Fastening of glued plates
Glued joints shall be resistant to (or protected against) sunlight (UV, heat, etc.) and all environmental
effects or cleaning chemicals normally encountered in the manufacture and use of the craft.
Glued joints shall fulfil the requirements of one of the following items:
a) the inside pressure test (D.4.2);
b) the separation test (D.4.3);
c) the manufacturer's gluing procedure and conditions are followed and the bond strength checked
by calculation to meet test pressure in D.4.3.2.
The above requirements shall be verified after any change in material or gluing procedure.
Plates, with or without framing, are considered glued if they are fastened with mechanical devices,
such as bolts, rivets or screws, spaced more than 20t, where t is the nominal plate thickness defined in
Clause 7.
6.2.4 Stiffeners and attachments
Particular attention shall be paid to different elongation of stiff materiel (e.g. glass) connected with less
stiff material (e.g. GRP) frames/supports (see ISO 12215-5:2019).
6.3 Special requirements
6.3.1 Appliances fitted in area I
6.3.1.1 Requirements for all appliances
6.3.1.1.1 Maximum small side dimension for glazing in the hull.
The maximum unsupported area of any one appliance situated wholly or partly within area I shall be
