1. Temperature cycle testing
2.100 degrees conditions placed 2h, and then placed under the conditions of -20 degrees 2h, continuous cycle of three days, samples should be no cracks.
3. After testing samples ,no crack.

1.Cold hot circulation test.

2.Under 100 conditions lays aside 2h, again under -20 condition laysaside 2h, continuously circulates 3 day, the sample should not havethe crack.

3.After the test the sample does not have the crack.

Test on temperature circle
Under 100C, 2h is a must; under 100C plus 20C, 2h is a must too; do so like the above for 3 days before the sample should be no crack or fracture.
Through a series of experiments, the sample has no crack or fracture absolutely.

1.The cold heat tests circularly
Under 2.100 degrees condition place a 2 hs, again-under 20 degrees condition place a 2 hs, circulate for 3 days in a row, the sample should have no crack.
3.The sample has no crack after testing.
