General Safety Practices
This section provides information about safety issues that pertain to
servohydraulic systems in general. These issues include statements to the
intended use and foreseeable misuse of the system, the hazard zone, definition for
the graphical hazard labeling that is affixed to your product, and other (more
general) safety information that relates to the high-pressure and high-
performance characteristics of MTS servohydraulic systems.
MTS test systems are designed to generate motions and forces and impart these
motions and forces into a test specimen.
When you prepare to operate the system and during system operation, ensure the
following:
• Do not use or allow personnel to operate the system who are not
experienced, trained, or educated in the inherent dangers associated with
high-performance servo hydraulics and who are not experienced, trained, or
educated with regard to the intended operation as it applies to this test
system.
• Do not disable safety components or features (including limit detectors,
light curtains, or proximity switches/detectors).
• Do not attempt to operate the system without appropriate personal safety
gear (for example, hearing, hand, and eye protection).
• Do not apply energy levels that exceed the maximum energies and velocities
for the system design. Refer to the system specifications.
• Do not test a specimen that exceeds the minimum (if applicable) or
maximum allowable mass. Refer to the system specifications.
• Do not use specimens that are combustible, flammable, pressurized, or
explosive.
• Do not use humans as specimens or allow humans to ride in or on the test
specimen or the test system for any purpose unless the system is man-rated
and all associated safety conditions are strictly enforced.
• Do not modify the system or replace system components using parts that are
not MTS component parts or effect repairs using parts or components that
are not manufactured to MTS specifications.
• Do not operate the system in an explosive atmosphere.
• Do not use the system in a test area where uncontrolled access to the test
system is allowed when the system is in operation
• Do not operate the system unless an interlock is installed to monitor supply
pressure into the HSM and initiate a system interlock if a low or no pressure
event occurs.
