    Rationale

    New research confirms that the test results depend upon the type of screen used for this test. To improve test accuracy, a uniform screen design must be use. The proposed screen design (FIG. 10) contains an integrated PTFE gasket that will reduce false positive results caused by rough screen material damaging the test specimen. To provide a better seal closed-cell foam is recommended instead of PTFE string.
