Introduction
This document applies to floating leisure articles for dynamic use of Class C (see Figure 1 for distinction
between Classes C1, C2 and C3 products). Examples of Class C products can be seen in informative Annex C.
Most technical requirements in this document are derived from the overriding property of the products to
provide high speed rides when towed by fast motorboats. Thus, space per person and means to hold tight
reliably and comfortably and without entrapment or entanglement is an important subject. This document
also addresses safety requirements concerning towing ropes.
Safety and performance of the products are tested by practical tests under all conditions and manoeuvres,
including the issue of a quick release in case of an emergency as well as residual buoyancy.
This document also includes requirements on comprehensive consumer information, including a set of non-
verbal communication gestures.

4 Safety requirements and test methods
4.1 General
Construction of a floating leisure article shall be such that it corresponds in terms of design, dimensions,
safety, strength and durability to its intended use. The requirements set out in this document were chosen
to ensure compliance of the above construction. When floating leisure articles provide buoyancy in several
components, then requirements apply to all components. Floating leisure articles of Class C shall provide
residual buoyancy if one air chamber fails. This residual buoyancy shall maintain the safety of the device
even if its function is lost. The following safety requirements are therefore related to:
— design;
— sizing;
— materials;
— strength;
— performance;
— information.
Towables of all classes shall be designed in a way that the rider, when in the intended position(s), can always
at least partially be seen by the observer for communication purposes by and with the observer.
Class C products shall be marked with the safety information markings, as specified in ISO 25649-2:2024,
Table 8.
4.2 Test conditions
If not otherwise stated, all tests shall be carried out at an air temperature of (20 ± 3) °C.
4.3 Design
4.3.1 General
With regard to design and shape, there is a certain number of constant types of towables, as described in
the introduction. The entire product group of towables is however subject to continuous change in terms
of shape and function. For that reason, the space-per-person requirements shall be applied in a way that
satisfies safety and performance if these parameters depend on distinct body positions for which an
available area should be provided. This applies in particular if use by children is included.
ISO 25649-5:2024(en)
4.3.2 Sizing, admissible number of users and maximum load capacity
4.3.2.1 Sizing
Towables shall be sized according to their admissible number of passengers. The size shall be communicated
to the user by applying, on the packaging and on the product, the safety information symbols “number of the
users, adults/children” and “user’s body weight range … to …kg” as specified in ISO 25649-2:2024 (Figure 22
and Figure 24 respectively).

4.3.5 Grab handles
4.3.5.1 Grab handles availability and strength
There shall be at least one grab handle for each admissible user. The handles or other means for holding shall
be positioned in a way to allow holding when sitting on or in the intended user position(s).
Any handle used shall not have a gap between the handle and the surface of more than 30 mm. The gap shall
not increase when pulled by a force of at least 300 N, thereby preventing hand or finger entrapment.
Grab handles shall meet the tensile test as specified in 4.3.5.2. Any means of holding on shall be designed to
avoid entanglement or entrapment.
4.3.5.2 Test methods
Visual inspection and measurement are required.
To measure the strength of handles, start with the towable fully inflated and held rigidly near the handle
attachments.
th
Use a rigid force applicator the width of the hand of a 50 percentile male (9 cm) and apply a tensile pre-load
force of 50 N. Apply a tensile force of at least 1 kN.
4.3.5.3 Foot and fingers entrapments
4.3.5.3.1 Foot entrapment through handle opening
In order to avoid foot entrapment all handles attached to the towable shall not allow the passage of the foot
probe as specified in ISO 25649-1:2024, 5.2.1.4.1 when this probe is pulled into the handle opening as shown
in Figure 2b), under the test force F of 50 N.

4.3.5.3.3 Finger entrapment on handle components
In order to avoid entrapment of fingers, the inner diameter of hoses, tubes and other similar openings shall
be < 8 mm or > 25 mm.
The test shall be performed according to 4.4.
4.3.6 Quick release system for C1 towables
4.3.6.1 Design requirements
The design of the quick release system shall indicate how to trigger it. The direction of triggering shall be
permanently identifiable.
The part of the release system which is used for triggering, i.e. the triggering element, shall have a contrasting
colour to the other parts of the release system surface.
The release system should be free from finger entrapments, squeeze and shear points. Edges that could
come into contact with the user's hands during use or handling and maintenance should not be sharp, e.g.
deburred, broken, rolled or processed with comparable techniques.
The space of activation shall not be restricted at any time by any part.
A release system ready for test for each test condition shall be an integral part of the C1 towable provided by
the manufacturer and/or supplier.
This also relates to soft parts or components of the release system which can, while being gripped and used
for triggering, deform and/or tilt and consequently obstruct the actual movement of triggering. While being
triggered, no part or component of the release system should impact the user's hands.
4.3.6.2 Test methods
Quick release system test shall be performed as visual inspection and verification.

The test shall be performed according to 4.4.
4.3.8 Residual buoyancy
4.3.8.1 Requirements
All floating Class C devices shall provide residual buoyancy after failure of the air chamber most likely
to cause the biggest loss of buoyancy. The amount of residual buoyancy shall be not less than 60 N per
admissible person. During the practical in-water tests, it shall be proven that each admissible person can get
hold to the remaining structure (details see 4.4).
4.3.8.2 Test method
Open the valve to deflate the chamber most likely to cause failure. Measure the residual buoyancy of the
remaining structure to determine if the 60 N per person requirement is satisfied.
