Preliminary Pages
Materials testing systems are potentially hazardous.
Materials testing involves inherent hazards from high
forces, rapid motions and stored energy. You must be
aware of all moving and operating components which
are potentially hazardous, particularly the actuator in a
servohydraulic testing system or the moving crosshead
in an electromechanical testing system.
Whenever you consider that safety is compromised,
press the Emergency Stop button to stop the test and iso-
late the testing system from hydraulic or electrical
power.
Carefully read all relevant manuals and observe all
Warnings and Cautions. The term Warning is used
where a hazard may lead to injury or death. The term
Caution is used where a hazard may lead to damage to
equipment or to loss of data.
Ensure that the test set-up and the actual test you will
be using on materials, assemblies or structures consti-
tutes no hazard to yourself or others. Make full use of
all mechanical and electronic limits features. These are
supplied for your safety to enable you to prevent move-
ment of the actuator piston or the moving crosshead be-
yond desired regions of operation.
The following pages detail various general warnings
that you must heed at all times while using materials
testing equipment. You will find more specific warn-
ings and cautions in the text whenever a potential haz-
ard exists.
Your best safety precautions are to gain a thorough un-
derstanding of the equipment by reading your instruc-
tion manuals and to always use good judgement.
