Water ingress in immersion suits: UK21/L009

Adopted EU recommendation LSA-018. UK approved recommendation on the testing standards of immersion suits.

Question

IMO Res. MSC. 81(70) Part 1, 3.1.9, states “the ingress of water into the immersion suit should not exceed a mass of 500g”. However, this does not consider the scenario in which the body inside the suit remains dry, but the material traps water in excess of 500g. Furthermore, it is identified that the IMO testing standard does not specify any standing time to permit excess water to run off the exterior prior to water weight measurement.

In the above scenario, would the immersion suit be considered compliant with testing standards?

Recommendation

No. In any case the ingress of water into the immersion suit or anti-exposure suit should not exceed a mass of 500g in accordance with the existing text of MSC 81(70) Part 1 Section 3.1.9.

In the scenario described above, the UK Approved Body and manufacturer may make a professional judgement and may make use of international industry accepted test methods, i.e., the Leakage Test procedures described in EN ISO 15027-3 [footnote 1].
