Specimen Installation
The procedure to install a specimen varies due to the variety of test fixtures, grips, and the type of specimen
being installed. This section should be considered a guideline. You need to modify this procedure to suit your
equipment.
Prerequisites
You must have the necessary grips and/or fixturing installed.
Note:
When changing hydraulic grips, make sure you cap or plug the hydraulic hoses when removed to
prevent oil spillage. Oil spillage can create an environmental concern and slippery surface that can
cause personal injury. Promptly clean up any oil that might have spilled when hoses were removed.
You must also have the controller set up to control the actuator movement, and you must have a test program
defined.
Warning:
The crosshead is very heavy.
A dropping crosshead can crush hands, damage grips, and smash specimens.
Be careful when working in a crush zone. To reduce the hazards in this procedure, observe the
following:
Set and enable displacement interlocks to limit the actuator’s movement.
Ensure that the crosshead is locked.
Ensure that the columns are clean and dry.
Keep your hands out of the crush zone except when performing the steps needed to complete
this procedure.
