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.
Hazard - Set appropriate limits before running waveforms, tests or loop tuning.
Operational limits are included within your testing system to suspend motion or shut off
the system when upper and/or lower bounds of actuator or crosshead travel, or force or
strain, are reached during testing. Correct setting of operational limits by the operator,
prior to testing, will reduce the risk of damage to test article and system and associated
hazard to the operator.
High/Low Temperature Hazard - Wear protective clothing when handling
equipment at extremes of temperature.
Materials testing is often carried out at non-ambient temperatures using ovens, furnaces
or cryogenic chambers. Extreme temperature means an operating temperature exceeding
60 °C (140 °F) or below 0 °C (32 °F). You must use protective clothing, such as gloves,
when handling equipment at these temperatures. Display a warning notice concerning
low or high temperature operation whenever temperature control equipment is in use.
You should note that the hazard from extreme temperature can extend beyond the
immediate area of the test.
Electrical Hazard - Disconnect the electrical power supply before removing the
covers to electrical equipment.
Disconnect equipment from the electrical power supply before removing any electrical
safety covers or replacing fuses. Do not reconnect the power source while the covers are
removed. Refit covers as soon as possible. Ensure any fluids used during testing are
suitably contained.
