Definitions
Safe Working Load - The maximum
recommended working load. This is set as a
quarter (1/4) of the Breaking Load and makes
an allowance for factors such as corrosion,
fatigue and dynamic loads.
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 when used in a mooring
operation.
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.
