The Standard for Safety for Marine Lifesaving Appliances: Immersion Suits

UL 9560 covers performance and safety requirements and test methods for:

i.          immersion suit systems;

ii.         constant wear suit systems; and

iii.        abandonment suit systems. 

The suit systems covered by this standard are intended to reduce the risk to the user of cold water or thermal shock and hypothermia in the case of cold water immersion while providing acceptable flotation to reduce the risk of drowning.  Constant wear suits are intended not to impair the user’s ability to perform survival actions or normal working duties. 

The suit systems covered are also intended to be used on vessels operating in a Polar environment (operating at temperatures below freezing) and anti-exposure environments. 

This standard is applicable for dry and wet suits.
