Door is secured with over-center latches

Loading Levers (two levers per assembly)
Aluminum lever with a 5:1 ratio applied loads from less than 20 lbs to over
150 lbs
Roller bearing lever pivot
Lever support and sample mount structure fabricated from modular aluminum
materials
Adjustable loading jack to enhance sample loading
Incremental spacers provided reduce potential energy of falling weight(s)
Lever is counter-balanced with linkage and upper grip

Specimen Grips (two sets per assembly) (upper &lower)
Case Hardened Carbon Steel
Straight serrated grip faces
Adjustable upper grip linkage
Accommodates Specimens up to 6″ long X ½” to 1 ¼” wide X 1/8″ to 3/8″ thick
Articulating lower grip mount to facilitate specimen alignment
Grip/Specimen Alignment Jig

Timer / Switch (one assembly per lever)
Electrical resettable timer that reads out to 00000.0 hour
Adjustable position limit switch that halts the timer upon sample failure

Heat Source / Temperature Control
Digital Temperature Controller
Process Temperature & Set Point Temperature Indication
PID process control with Auto-tune programming
RTD Temperature Sensor positioned within 3″ of the test specimen
120 VAC power requirements
Durable Controlled Heat Source of an appropriate watt density

Loading Weights
Flexible Weight Loading Linkage to reduce direct impact upon specimen
failure
Metallic incremental weight disks provide quick accurate specimen loading
Weight provided per lever:
(10) 3 pound disks
(2) pounds metallic shot
The weight loading linkage features a container to allow metallic shot to attain the
precise weight
