What is ISO 11592-2 about?
ISO 11592 discusses standards for the determination of maximum propulsion power rating of small craft. ISO 11592-2 focuses on the craft with a length of a hull. ISO 11592-2 specifies the requirements for determining the maximum propulsion power rating using manoeuvring speed for engine-driven craft with a length of the hull (LH, as defined in ISO 8666) between 8 m and 24 m.
ISO 11592-2 is applicable to craft with a calculated Froude number (Fn) ≥ 1,1.
Note: ISO 11592-2 does not apply to inflatable craft, craft designed and constructed solely for competitive racing (racing craft), craft primarily designed not to be engine driven
Note: ISO 11592-2 does not specify craft constructional strength requirements related to maximum propulsion power rating and does not guarantee stability under all conditions of seaway, wind, wakes and waves.
Who is ISO 11592-2 for?
ISO 11592-2 on the propulsion power rating for small craft is applicable to:
- Maritime manufacturers
- Small craft manufacturers
- Water transport engineers
- Ship and marine industries
- Quality control professionals
Why should you use ISO 11592-2?
ISO 11592-2 provides you with test procedures which helps to derive maximum propulsion power rating using the results of the tests. These tests shall be used for determining the maximum manoeuvring speed. ISO 11592-2 goes through the tests such as quick turn test, avoidance line test, through which you can ensure your crafts can perform as desired.
Obtaining ISO 11592-2, helps small craft manufacturers to make suitable formulations and preparations for propulsion power rating (as per specification for marine applications). Also, manufacturers can demonstrate the reliability of their products and build trust in their use throughout the marine supply chain by adhering to ISO 11592-2.
What’s changed since the last update?
BS EN ISO 11592-2:2021 supersedes BS EN ISO 11592-2:2019. BS EN ISO 11592-2:2021 includes some technical changes concerning BS EN ISO 11592-2:2019. These include:
- The dates of the normative references have been corrected in Clause 2 and throughout the standard
- The text that referenced Figure 1 has been corrected in Clause 7
- Reference to the CIN has been deleted from Clause 8
- In Clause 10, the first paragraph has been slightly reworded as a Note, to make an informative reference to ISO 10240, which has been moved from Clause 2 to the Bibliography
