Floating leisure articles for use on and in the water - Part 7: Additional specific safety requirements and test methods for Class E devices
1Key Takeaways
This document is applicable for Class E floating leisure articles for use on and in water according to This document is applicable with ISO 25649-1 and ISO 25649-2. Class E devices are intended for use in bathing areas or in protected and safe shore zones. NOTE 1 Typical products forming Class E (see Annex F): — infla…
2Expert Interpretation
This in-depth analysis of ISO 25649-7:2017's safety requirements for Class E leisure aquatic equipment covers key technical indicators such as structural integrity testing, load capacity calculation, and stability verification for inflatable boats. It is suitable for manufacturers and testing agencies.
Analysis of the core content of the standard
| Technical dimensions | Class E equipment requirements | Test methods | Key parameters |
|---|---|---|---|
| Hull integrity | Load-bearing accessories maintain airtightness under a load of 1kN (leisure boat)/2kN (work boat) | Load test for 1 minute | Test rope diameter8mm |
| Static stability | No capsizing when fully loaded | According to the formula mt=(0.67×n×75kg)+(0.67×37.5kg)counterweight | Adult load 75kg / Child 37.5kg |
| Residual buoyancy | Retain 50% of the rated load capacity after the maximum buoyancy chamber fails | Volume measurement error ≤ 3% | Buoyancy volume calculation formula: m=(0.5×V×1000)-M |
Detailed explanation of key test requirements
1. Hull drainage system verification
Inflatable boats with an integral stern must be equipped with at least one drain plug or bailing system. Watertightness testing must be performed at maximum operating pressure during the test. After 20 minutes of static load, check for internal water seepage.
2. Maneuverability Test
In the event of failure of any buoyancy chamber, the inflatable boat must be able to complete a 50-meter straight-line journey using the intended propulsion method. Testing must be conducted in waves with an average height of 300 mm, with particular attention paid to the effectiveness of paddling as an emergency propulsion method.
Technical Evolution Background
This standard fills the regulatory gap between the EN 71 toy standard and the ISO 6185 inflatable boat standard, establishing unified specifications for leisure equipment with a buoyancy range of 1.2 m to 1800 N. The 2008 edition first introduced the concept of residual buoyancy, and the 2017 edition adds the following:
- Engine power calculation formula: Pmax=1.2×F(d) (for models with stern engines)
- Sailboat test course specifications (60° true wind angle sailing verification)
- Children's seat area requirement is 0.23m²/person
Implementation recommendations
- Material selection: Non-reinforced hulls should use impact-resistant plastics specified in ISO 179-1
- Test environment: All tests should be conducted at (20±3)℃
- Marking requirements: The packaging must include an outline dimension drawing, and the hull must indicate the maximum working pressure
- Instructions: Maintenance instructions such as salt cleaning and professional repair trigger conditions must be included
