Overview
SIST EN ISO 12216:2022/A1:2022 is a vital amendment to the international standard specifying strength and watertightness requirements for windows, portlights, hatches, deadlights, and doors on small craft. Developed by ISO/TC 188 in collaboration with CEN/TC 464, this amendment ensures enhanced safety and reliability of openings on small vessels. The standard supports compliance with Directive 2013/53/EU relating to recreational craft and personal watercraft, helping manufacturers meet essential safety and performance criteria. This document updates previous definitions and requirements by removing ISO 11812:2020 reference and introducing new terminologies for sill types and companionways.
Key Topics
-
Strength and Watertightness Requirements
The standard defines critical structural integrity and sealing criteria for all opening fixtures-windows, portlights, hatches, deadlights, and doors-to prevent water ingress and maintain vessel safety under marine conditions.
-
Terminology Updates
- Sill: A barrier above which water may enter companionway openings and potentially downflood the craft.
- Fixed sill: A permanent, integral deck part forming a sill.
- Semi-fixed sill: A movable but permanently installed closing device that raises the sill height when in use, such as sliding hatches or hinged doors (excluding removable washboards).
- Sill height (hS): Vertical distance from the sill top to the nearest deck point.
- Minimum sill height (hS min): The smallest allowable sill height designed to ensure watertight integrity.
- Flush deck companionway: A companionway fitted on an even deck surface without recess.
-
Companionway Definition
Openings designed for crew access fitted with opening appliances like doors or hatches, with provisions for multiple companionways on the craft.
-
Amendment Changes
Removal of ISO 11812:2020 normative reference, revised definitions for sill and companionway, updated table titles and figure replacements to clarify sill measurement and construction.
Applications
-
Small Craft Manufacturers
Use SIST EN ISO 12216:2022/A1:2022 to design and produce compliant windows, portlights, hatches, deadlights, and doors that meet structural strength and watertightness criteria, enhancing overall vessel seaworthiness.
-
Marine Surveyors and Inspectors
Assess opening fixtures on recreational boats against standardized sill height requirements and sealing performance to ensure safety regulations are fulfilled.
-
Regulatory Compliance
Supports manufacturers and authorities in meeting EU Directive 2013/53/EU essential requirements, enabling market access and legal conformity for small craft within EU and EFTA member states.
-
Maintenance and Safety Professionals
Provides guidance for evaluating and maintaining watertight seals and structural soundness of critical openings in small vessels to mitigate water ingress and flooding risks.
