Test* Temperatures and Duration Results
Maximum Temperature Long-term at 10 hr: 320°F (160°C) No effect on tag. Tag remained the same in appearance and RFID performance/function. There was no sign of peeling, tearing or destruction. The tag read normal after the tests. *Test is not limiting.
Standard at 5 min: 360°F (182°C)
Short-term at 90 sec: 400°F (204°C)
Minimum Temperature -40°F (-40°C)
Temperature Cycling The tag was cycled to 400°F at equilibrium for five times. Between each cycle, it was air cooled to room temperature and read with an RFID reader.

RFID Performance


RFID Protocol UHF EPC Class 1 Generation 2
Tag Type Passive Read/Write
Frequency Range 860 ~ 960 MHz (Global)
IC Impinj Monza 3


Tested Polarization:


Tag performance was experimentally measured in an anechoic chamber with a known set of experimental variables. The antenna used for measurements was linearly polarized and of monostatic configuration. The direction of tested polarization is as follows.













Optimal Read Range* on Different Material Surfaces:

*Tag performance was measured free of material influence, on a dry wood, window glass, thermoplastic, and steel slabs. Actual read ranges may differ depending on conditions such as environment, tag placements, hardware, etc.
