GASKET AGING TEST 1.0 ABSTRACT

1.1 Object

Subject the supplied Gasket Material to the Gasket Aging Test outlined in NEMA 250, Section 5.14.1, as requested in Wavetronix LLC Purchase Order No. 10981, dated February 15, 2006.

1.2 Conclusions

On completion of testing, tensile strength values are greater than 75% of initial values. On average, elongation values are greater than 60% of initial values. Therefore, the test material samples were determined to have passed the requirements of NEMA 250, Section 5.14.

2.0 UNIT(S) TESTED

MANUFACTURER: WAVETRONIX LLC

DEVICE: Gasket Material for IQ2 Enclosures

4.2 Procedure

The test samples were placed inside the temperature chamber and subjected to a temperature of 70°C for a period of 168 hours. The samples were then stabilized at ambient conditions. The aged gasket and an unaged gasket were then subjected to a tensile test. Figure No. 1 depicts a temperature chart showing chamber temperature during a typical 24-hour period of exposure. Figure Nos. 2 through 5 include graphic and print-out test data. Photograph Nos. 1 and 2 provide views of the test setup.

4.3 Results

On completion of testing, tensile strength values are greater than 75% of initial values. On average, elongation values are greater than 60% of initial values. Therefore, the test material samples were determined to have passed the requirements of NEMA 250, Section 5.14.
