ASTM D1709 Dual Mode Design Fall Darts Impact Testing Machine , Method A & B

Product Summary:

Fall darts impact tester apply to plastic film or chip which thickness less than 1mm impact by fall darts

in a given great freedom to fall, test the impact quality and energy were when 50% plastic film or chip

was damaged.

Working Principle:

When trial is beginning,firstly choice test methods, estimates that an initial quality and Δ m value, and

than testing, if the first sample damaged, with Jordan farmar Δ m reduce falling body quality; If the first

don't break, should be in Jordan farmar Δ m increase fall body quality, based on to test. In a word, use

farmar to reduce or increase the quality of fall, depends on the a sample for damage or breakage.

After test 20 samples, to calculate the damage total N, if N = 10, the experiment is complete; If N<10,

supplement the sample, continue to test until N=10; If N>10, supplement the sample, continue to test

until no damage is equal to the total number is 10, finally automatic calculation the shock results by the

system.

Meet Standard:

GB 9639,ASTM D1709,JIS K7124

Basic Operation Steps:

System power→Choose experimental method→Estimates that initial impulse and Δm→System automatically

calculation progress→Automatic judgment whether meet the end conditions→Test results show→Print test

report→Off-test
