3.13 buddy line — length of cord which can be tied or otherwise fixed to another person or to that person’s PFD or other objects, so as to keep a user in the vicinity of that person or object with a view to making location and thus rescue easier
3.14 lifting loop — device which facilitates manual recovery of a person from water
3.15 sprayhood — cover brought or placed in front of the airways of a user in order to reduce or eliminate the splashing of water from waves or the like onto the airways and thereby to promote the survival of the user in rough water conditions
3.16 protective cover — cover that is normally in place over the functional elements of a PFD in order to protect them from physical damage, or snagging on external objects
NOTE 1 The protective cover may be designed to provide additional properties, i.e. to make the PFDs suitable for use when the subject is exposed to additional hazards, e.g. significant abrasion, molten metal splash, flame and fire.
NOTE 2 The inflatable chamber of an inflatable PFD is an example of a functional element.
3.17 overpressure relief valve — valve which may be used in an inflatable system to avoid the likelihood of destruction caused by overpressure
3.18 whistle — device which, when blown by mouth, produces an audible sound which can aid in the location of the user
3.19 hybrid-type PFD — PFD of combined buoyancy types, i.e. inherent and inflatable
3.19 DV Dl Modification by adding a note to the hybrid- type PFD definition as folio ws:
NOTE — An inflatable PFD with minimal inherent buoyancy to meet the uninflated buoyancy test (see 5.3.1.2) is not considered a hybrid-type PFD.
3.2ODV D2 Modification by adding bunching definition to clause 3:
bunching — curling or folding of internal buoyant material upon itself, from its original position, within the envelope
3.21 DV DT Modification by adding sheltered waters definition to clause 3:
sheltered waters — water with protection from significant breaking waves, current, or strong winds, where the possibility of being blown or carried away from shore or place of safety is minimal
3.22 DV DT Modification by adding offshore definition to clause 3:
offshore — water that is unprotected and influenced by a variety of threat conditions such as waves, tide, currents, or wind, which may be at sea or on inland waters
3.23DV DT Modification by adding primary inflation definition to clause 3:
primary inflation — means of inflating an inflation chamber that meets the applicable PFD performance requirements and that requires the least amount of intervention by the user, generally according to the following order of precedence: automatic (easiest), manual (second), and oral (most difficult)
4.1.2 Buoyancy aids
These devices should be comfortable for continuous wear and provide lift, without significant face-up turning ability, to float the conscious user with the level of support marked on the device. Buoyancy aids shall at least be suitable for sheltered waters, but at higher performance levels may be suitable for some users in other waters.
4.1.3 Special purpose lifejackets and buoyancy aids
These devices perform as in 4.1.1 and 4.1.2 with different levels of support, but have modifications related to special applications for use. These applications shall not relate to essential requirements such as in-water performance, stability and safety in use. The specific conditions for use shall be stated on their label to maintain essential requirements.
