Test Procedure1) Fix the test samples on the sample supporting plates by clamping the jaws on each side.2) Zero the cycle counter3) Start the test and inspect the samples after every 5,000 cycles during the first 25,000 cycles. After this, inspect the samples after every 10,000 cycles4) After 50,000 cycles or at any time that impacting force decreases, stop the machine and re-calibrate the impact force. To do this, follow steps 3-6 on Equipment Set-up and Preparation.5) Remove the test samples at the “failure point” and mark the area on the specimen where failure/problem is found. If failure has not occurred after 125,000 cycles, discontinue the testing and report the result as “125,000 + cycles”.EvaluationTogether with the number of the lowest cycles at which any of the samples fails the following items define the visible failure points of the different materials:1) For Assembled / stockfitted partsFailure point is defined as “any visible changes on the surface of the test sample including cracks, breaks, adhesion separation, coating peel-off/delamination; or any damage seen through a magnifying glass.2) For AircellFailure point is defined as “any visible signs of collapse, compression, air leakage, softening, adhesion separation/delamination, or, any damage seen thru a magnifying glass.”Requirements
