ASTM Test Method
D-4526 3
1 Static
= Residual voltage on surface of tape after unwind @ 12 in./min. as measured by 3M Model 709
static sensor.
2 Outgassing = Dynamic headspace analysis of volatile components collected during a 4 hr @ 80°C heat
cycle using a Hewlett-Packard Model 5890 Series II gas chromatograph coupled with a Hewlett-Packard
Model 5989B mass spectrometer.
3 ASTM test method modified per footnote #2 above.
