Full title and description

St ISO 12216-2020 — Small craft — Windows, portlights, hatches, deadlights and doors — Strength and watertightness requirements. This International Standard specifies technical requirements and test methods for structural openings and closure devices on small craft that are critical to the craft’s watertight integrity, with requirements scaled to craft type, design category and installation location.

Abstract

The standard defines strength and watertightness requirements and corresponding test methods for windows, portlights, hatches, deadlights and doors fitted to small craft with a hull length (L_H) up to 24 m (as defined in ISO 8666). It applies only to appliances considered critical for the craft’s watertightness and excludes openings and non‑opening devices fitted below area I. The document also takes the craft’s design category and the equipment location into account.

Scope

Applies to windows, portlights, hatches, deadlights and doors on small craft with hull length L_H up to 24 m. The standard is concerned only with those appliances that are critical to watertightness (i.e., whose failure could admit water into the craft). It excludes openings and non‑opening devices fitted below area I and is written with recreational and other small craft in mind (not lifeboats or commercial/work boats used in severe conditions unless specifically referenced). The standard references ISO 8666 for hull‑length definitions and aligns requirements with the craft’s design category and installation location.

Key topics and requirements

• Definitions and design‑category references (linking to ISO 8666 and the ISO small‑craft series).
• Strength requirements for plates, frames and fixings — test loads and pass/fail criteria for structural strength.
• Watertightness test procedures for installed and standalone devices, including pressure/duration criteria and acceptance checks.
• Requirements that account for location on the craft (deckhouse, superstructure, below/above area I) and intended service conditions.
• Marking, documentation and information to be supplied by manufacturers for correct installation and maintenance.
• Normative references and cross‑references to related small‑craft standards and test methods.

Typical use and users

Used by naval architects, boatbuilders and component manufacturers to design, test and certify windows, portlights, hatches and doors for small craft. Also used by test laboratories, surveyors, classification societies, conformity assessment bodies, regulators and procurement/specification teams when verifying watertightness and strength performance for leisure and other small vessels.

Related standards

Key related documents include ISO 8666 (small craft — principal data / hull‑length definitions), the ISO 12217 series (stability and buoyancy / design‑category assignment), and relevant regional/adopted versions (for example EN/BS adoptions and amendments). The ISO 2020 edition of 12216 has at least one amendment (Amd 1:2022) and national/adopted versions (EN/BS) that consolidate the ISO text and amendment.

FAQ

Q: What is this standard?

A: ISO 12216:2020 is an international standard that specifies strength and watertightness requirements and associated test methods for windows, portlights, hatches, deadlights and doors on small craft (hull length up to 24 m).

Q: What does it cover?

A: It covers technical requirements and laboratory/installation test methods for the structural strength and watertight performance of critical openings and closure devices, scaled by craft type, design category and the device’s location on the craft. Openings fitted below area I are excluded.

Q: Who typically uses it?

A: Naval architects, boat and component manufacturers, test laboratories, surveyors, classification bodies and regulators use the standard for design, testing, certification and procurement of small‑craft closures.

Q: Is it current or superseded?

A: The 2020 edition (edition 2) is the current published ISO document and it has an amendment published in 2022 (ISO 12216:2020/Amd 1:2022). ISO indicates the 2020 edition is in the published lifecycle and a committee draft to revise the standard has been recorded, so users should check for any further revisions or national adoptions when applying the standard.

Q: Is it part of a series?

A: Yes — it is part of the ISO small‑craft family of standards (ICS 47.080) and is commonly used alongside standards such as ISO 8666 (principal data / hull length definitions) and the ISO 12217 stability and buoyancy series to determine design category and compliance.
