ISO 25649-7:2024 — Floating Leisure Articles — Safety Requirements and Test Methods for Class E Devices

Understanding ISO 25649-7 and Class E Devices

ISO 25649-7:2024 specifies safety requirements and test methods for Class E floating leisure articles — inflatable and rigid-inflatable boats designed for recreational use on water. Class E devices include manually propelled boats (rowing boats, paddle boats) and small boats with integrated oar or paddle systems. Unlike Class D structures designed for jumping and climbing, Class E devices focus on safe transportation, stability while seated, and reliable propulsion.

The standard addresses materials, construction, functional components, and comprehensive safety testing. Key areas include hull integrity, manual lifting and carrying devices, rowlock and oar specifications, hull drainage, towing attachments, seating systems, static stability, dimensional stability during boarding, freeboard requirements, and emergency re-entry from water.

Hull Integrity and Construction Requirements

The hull integrity requirements (Clause 5.2) form the foundation of Class E safety. The standard mandates that inflatable hulls maintain specified internal pressure without significant pressure loss over a defined test period. This ensures that the boat remains buoyant and stable throughout its intended use. The conditioning procedure (5.1) requires products to be stabilized at standard environmental conditions before testing, eliminating temperature and humidity variables from the evaluation.

Material requirements (Clause 4) address the specific demands of inflatable boat construction. Materials must demonstrate resistance to UV degradation, flex cracking, and seam separation. For inflatable boats, the seams are particularly critical — they must withstand both pressure loads and the mechanical stresses of launching, beaching, and storage.

Manual lifting and carrying devices (5.3) are required on boats exceeding a specified weight threshold. These handles or straps must be tested to verify they can support the fully loaded boat weight without tearing or detachment. This seemingly simple requirement addresses a real safety concern — boats that cannot be safely carried by multiple persons present risks during transport and launching.

Rowing Systems and Propulsion Safety

The standard’s requirements for rowlocks and oars (5.4) are particularly detailed. Rowlocks must provide secure oar retention while allowing free movement during normal rowing. The attachment system must prevent accidental disengagement — if an oar comes loose during vigorous rowing, the sudden imbalance can cause capsizing, especially in smaller boats.

Oars themselves must meet minimum dimensional and strength requirements. The blade area, shaft diameter, and overall length must be appropriate for the boat’s size and intended use. The standard specifies test methods for applying simulated rowing forces to verify structural integrity.

Stability Testing and Freeboard Requirements

Static stability testing (6.2) evaluates the boat’s resistance to capsizing under asymmetrical loading. The test simulates the worst-case scenario where all occupants shift to one side — for example, when everyone leans over to look at something in the water. The boat must demonstrate that it can maintain a heel angle of 15° or less under this condition, providing sufficient margin before water enters over the gunwale.

Dimensional stability during boarding (6.3) addresses the critical moment when users enter the boat from a dock, platform, or the water itself. Boats that deform excessively during boarding can tip or eject occupants. The standard specifies maximum allowable deformation under boarding loads.

Freeboard (6.4) — the distance from the waterline to the gunwale — is a fundamental safety parameter. The standard specifies minimum freeboard requirements for both unloaded and loaded conditions. Insufficient freeboard increases the risk of swamping from waves, wake, or occupant movement.

Re-embarkation and Emergency Systems

Class E devices must provide means for re-embarkation from the water (6.6). This requirement is often overlooked by casual users but is critical for safety — a person who falls out of a boat must be able to get back in without assistance. The standard requires that re-entry systems (such as boarding ladders, steps, or integrated handholds) be tested to verify functionality while wearing typical clothing and life jackets.

The towing device requirement (5.6) ensures that the boat can be safely towed if necessary. This is important for rescue scenarios or when the boat is used as a tender for a larger vessel. The towing attachment must have breaking strength significantly exceeding the loaded boat weight, with a safety factor specified by the standard.
