Appendix A: PST
Reliability and
Durability
3M Corporation has conducted extensive environmental testing on their
Automotive Acrylic Plus Attachment Tape. In addition, Savi has conducted
its own independent environmental tests of PST using SaviTag ST-410 as a
test platform. The U.S. Army (Tobyhanna Army Depot) has also tested PST
for use on surfaces treated with Chemical Agent Resistant Coating (CARC).
All these tests confirm that PST is an appropriate choice for mounting
SaviTags.
◆ Savi Technology successfully conducted the following tests upon
samples of 3M PST:
❖ Extreme temperature (–40º to +70º Celsius)
❖ Step test (200 pounds applied in shear)
❖ Shock (140g or 120 lbs.)
❖ Vibration (MIL-STD-810E)
❖ Salt fog (MIL-STD-810E)
❖ Corrosive liquids
❖ Peel test (50 pounds of peel force)
Savi’s tests confirm the excellent adhesion integrity and reliability of 3M
PST.
◆ 3M Corporation conducted a longevity test of PST. They found no
significant degradation in the performance of PST even after five years
of service on a test vehicle. As long as the surface is prepared properly,
PST will work reliably for five years or longer. See “Preparing the
Surface for PST Application” on page 20.
◆ 3M Corporation compared the peel strength of a new roll of PST versus
a roll that had been aged 21 months. In all cases, the aged roll matched
performance of the new roll in tests conducted over a 72-hour period.
