ISO 11336-2:2020

Overview

ISO 11336-2:2020 specifies technical requirements for the direct adhesive bonding of glazing into recesses or frames that form part of a large yacht’s structure. Focused on elastically bonded (not rigid) glazed openings, the standard applies to independent glazed openings integrated into adjacent structure and addresses design criteria, structural support, installation and testing to assure strength, weathertightness and watertightness. It complements ISO 11336-1 and is limited to local loads (weather, wind suction, accidental internal impacts and ship motion accelerations), excluding structural glazing that carries global ship loads.

Key topics and technical requirements

• Bonding materials: Requirements for adhesives, including physical characteristics (flexural and shear modulus, elongation, tensile strength, Shore hardness), environmental resistance and long‑term properties.
• Bonding arrangements: Configurations for glazing bonded to bulkheads or shell, limitations for sloped/overhead glazing and guidance on insulated glazed units (IGUs).
• Bonded joint design: Design loads and load cases (static, dynamic, fatigue and accidental internal loads), bondline parameter limitations and calculation guidance (worked examples in annexes).
• Installation and procedures: Surface preparation, bonding application guidelines, installation sequencing and laboratory/onsite curing practices.
• Testing and verification: Material testing, proof testing of bonded joints and acceptance criteria; includes personnel qualification and survey guidance.
• Scope exclusions: Fire-protected areas, glazed bulwarks, underwater glazing, pool glazing, polar-area glazing, unstepped IGUs and bonding that behaves non‑elastically.

Practical applications and intended users

ISO 11336-2 is essential for professionals involved in yacht design, construction and certification who need to ensure glazed openings perform reliably under marine service conditions. Typical users include:

• Naval architects and yacht designers specifying bonded glazing solutions
• Shipyards and fit-out yards installing bonded windows and deckhouse glazing
• Glazing and insulated glazed unit (IGU) manufacturers designing bondlines
• Adhesive suppliers qualifying materials for marine glazing applications
• Surveyors, certification bodies and QA/QC inspectors performing proof testing and acceptance checks

Benefits include consistent weathertight/watertight performance, predictable elastic behaviour under local loads, reduced leak and failure risk and clear testing and installation requirements for regulatory compliance.
