BA-7140 -A Cornell Type Tester for ASTM F1566:2014

The Cornell Type Tester with a button to complete the function, can be completely in 
accordance with the F1566 ASTM standard test procedures for testing, in the middle do not need manual adjustment can easily complete the 7 stages of the cumulative fatigue test 100000 times.
Cornell Type Tester Apparatus:
1. Testing Machine(Cornell Type Tester)—A machine that applies repeated, controlled, counted strokes of a round-end plunger/ram head (see Fig. 1) to the surface of the specimen. The readout on the load cell shall be digital, the “throat opening”(height between the plunger and rigid, level surface) shall be a minimum of 660.4 mm (26 in.), the load cell shall have a minimum capacity of 2225 N (500 lbf). The tester consists of a reciprocating plunger that repeatedly applies a preset deflection to the test mattress, and automatically measures and records any fatigue or failure produced in the process. The plunger is driven by an adjustable eccentric, allowing a variable stroke depth, and hence, an adjustable load. The plunger staff itself telescopes, allowing the plunger to be driven up and down independent of the eccentric. This feature is used in graphing the mattress.

FIG. 1 Cornell Type Tester ,Fully automatic one button to complete the test, do not need manual intervention and guardian, to save a test engineer.
2 Ram Head—A device designed to resemble closely the form of the average human buttocks. The tester consists of a reciprocating plunger that repeatedly applies a preset deflection to the test mattress, and automatically measures and records any fatigue.
