1. Inner surface resistance: 105-1010 (ω/SQ), which is better than the
requirements of the inner surface resistivity of 105-1012 (ω/sq) specified in
the national military standard.
2. Outer surface resistivity: less than 108 (ω/sq), which is better than the
requirements of the outer surface resistivity specified in the national military
standards of less than 1012 (ω/sq).
3. Static attenuation: <0.05 seconds, better than the <2 seconds
requirements stipulated in the national military standard
Other performance: electromagnetic interference attenuation, interception
strength, and water steam penetration are better than the requirements of
national military standards.
The first is the external resistance test method. The external surface
resistivity is less than 1.01012Ω. This method can only test the appearance
resistance of the inside of the anti -static packaging bag and the outer layer,
and the appearance resistance rate is 1.0105Ω to 1.01012Ω. It is not a test for
the resistance of the anti -static packaging bag shielding layer. Therefore, the
test result does not reflect the performance of the static shielding of the anti
-static packaging bag. There is a difference between the test results and the
shielding performance test requirements.
Second, the peak voltage test method of static induction is used to measure
the external resistance measurement method to measure the inductive peak voltage
as the indicator.
