This data shows the results of some of the tests carried out at our laboratory under the specific test conditions in<strong>tr</strong>oduced here.<br />
Variation in the type of test media, the phase of test media (gaseous or liquid), preparation of test specimen and test conditions<br />
such as pressure, temperature and duration, may cause the test results to be different from this data, but general monomer<br />
resistance levels of the seats in<strong>tr</strong>oduced here are <s<strong>tr</strong>ong>com</s<strong>tr</strong>ong>paratively as exhibited in this test data.<br />
