ISO 12216:2020/Amd 1:2022 PDF

Overview

ISO 12216:2020/Amd 1:2022 is an important international amendment to the ISO 12216:2020 standard, focusing on small craft windows, portlights, hatches, deadlights, and doors. This amendment specifically updates the strength and watertightness requirements for these components, ensuring enhanced safety and durability in marine environments. Developed by ISO/TC 188 in collaboration with CEN/TC 464, this document is vital for manufacturers, designers, and regulatory bodies involved in small craft construction and maintenance.

The amendment refines terminologies and clarifies technical definitions related to sills and companionways-key structural elements impacting water ingress protection. It offers practical guidance on evaluating and labeling sill heights, crucial for maintaining integrity under various operational conditions.

Key Topics

• Strength Requirements Components such as windows, portlights, and hatches must meet stringent strength criteria to withstand pressures encountered during marine operations.

• Watertightness Criteria Ensures that openings are designed and constructed to prevent water ingress, critical to vessel safety and habitability.

• Terminology Enhancements:

  • Sill: A barrier above which water can enter companionway openings and potentially flood the craft.
  • Fixed sill: Integral, permanent deck structures providing water barriers.
  • Semi-fixed sill: Movable but permanently installed elements complementing fixed sills (e.g., sliding sills).
  • Sill height: Vertical distance measurement essential for compliance evaluation.
  • Flush deck companionway: Companionway openings set flush with the deck, without recess.
  • Companionway: Crew access openings fitted with doors or hatches.

• Updated Testing and Labeling Guidelines Specific updates to sill height measurement and labeling for flush deck companionway hatches promote consistent application and compliance across the industry.

• Removal of Reference ISO 11812:2020 was removed as a normative reference, reflecting amendments to sill treatment and drainage specifications within this document.

Applications

ISO 12216:2020/Amd 1:2022 applies primarily to small craft manufacturers and marine equipment suppliers, helping to:

• Enhance the design and manufacturing of watertight doors, hatches, and windows to meet higher durability and safety standards.
• Support compliance verification during quality control, certification, and regulatory inspections.
• Provide clear guidelines for installers and engineers on sill construction and watertight barrier integrity.
• Assist maritime architects and naval engineers in implementing globally accepted specifications for companionway openings.
• Ensure vessels meet international safety requirements during construction and retrofitting, reducing risks related to water ingress under demanding sea conditions.

Related Standards

• ISO 12216:2020 – The base standard covering strength and watertightness requirements for small craft windows and hatches.
• ISO 11812 (withdrawn reference) – Previously referenced standard addressing watertight and quick-draining cockpit designs.
• ISO/IEC Directives – Guidelines for the development and maintenance of ISO standards, ensuring editorial and procedural consistency.
