Hazard - Press the Emergency Stop button whenever you consider that an
unsafe condition exists.
The Emergency Stop button removes hydraulic power or electrical drive from the
testing system and brings the hazardous elements of the system to a stop as
quickly as possible. It does not isolate the system from electrical power, other
means are provided to disconnect the electrical supply. Whenever you consider
that safety may be compromised, stop the test using the Emergency Stop
button. Investigate and resolve the situation that caused the use of the
Emergency Stop button before you reset it.
Flying Debris Hazard - Make sure that test specimens are installed correctly
in grips or fixtures in order to eliminate stresses that can cause breakage of
grip jaws or fixture components.
Incorrect installation of test specimens creates stresses in grip jaws or fixture
components that can result in breakage of these components. The high
energies involved can cause the broken parts to be projected forcefully some
distance from the test area. Install specimens in the center of the grip jaws in
line with the load path. Insert specimens into the jaws by at least the amount
recommended in your grip documentation. This amount can vary between 66%
to 100% insertion depth; refer to supplied instructions for your specific grips.
Use any centering and alignment devices provided.
Hazard - Protect electrical cables from damage and inadvertent
disconnection.
The loss of controlling and feedback signals that can result from a disconnected
or damaged cable causes an open loop condition that may drive the actuator or
crosshead rapidly to its extremes of motion. Protect all electrical cables,
particularly transducer cables, from damage. Never route cables across the
floor without protection, nor suspend cables overhead under excessive strain.
Use padding to avoid chafing where cables are routed around corners or
through wall openings.
