POLYOLEFIN 2:1 Heat-Shrink Tubing Oddy Test Results


Oddy Test Results for samples of Polyolefin 2:1 Heat-Shrink Tubing

TEST PROCEDURE: Oddy

An Oddy test was conducted on five samples of polyolefin tubing.

The test procedure was as follows: Each sample of polyolefin was enclosed in a separate glass vial with blanks of polished lead, silver and copper.  Half of the sample was placed beneath the blanks so that any effect of direct contact as well as volatile contaminates could be assessed.  Moist cotton was placed in the test vial, which was then sealed and exposed to 55ºF for 35 days.

A control vial was prepared in the same manner, without any sample, and exposed to the same conditions.
