DEFINITIONS
Safe Working Load -
The maximum
recommended working load. This is set as a
quarter (1/4) of the Breaking Load and allows
for factors such as corrosion, fatigue, shock
loads, harmonic loads, manufacturing defects
and material defects.

Release Load -
The maximum in-line load that
the whole assembly can release whilst
guaranteeing safe and reliable operation.
Note that as the load is released in water, this
is determined by the maximum upthrust from
the buoyancy.
Breaking Load -
The load that induces
structural failure in one or more parts of the
instrument causing the load to part from the
release mechanism.
Proof Load -
The load to which the actual unit
has been tested in the factory. This load
should be periodically applied to demonstrate
that the unit is still in a safe condition. This is
usually twice (x 2) the SWL. A Proof Load
Certificate can be provided upon request.
