## FAQ
- Q: Is the epoxy keyfob ATEX Zone 2 / 22 certified?
  A: The fob itself is a passive transponder with zero stored energy and no mechanical fault mode capable of producing a spark, so it qualifies under the passive-equipment clause of ATEX 2014/34/EU and the parallel IECEx / AS/NZS 60079 / NFPA 70 Class I Div 2 rules when paired with an ATEX-certified reader. Formal Zone 2 / 22 clearance is carried by the reader, not the fob — this is how virtually every passive-RFID hazardous-area credential is structured.
- Q: Can the epoxy keyfob survive food-plant CIP / SIP wash-down?
  A: Yes — cured epoxy is chemically resistant to typical food-plant CIP / SIP chemistry (quat ammonia 200-400 ppm, peracetic acid 80-150 ppm, caustic soda 1-2 % at 60-80 °C) for the tens-of-minutes contact times normal in daily wash-down. Sustained high-concentration hot-caustic or aggressive solvent immersion (MEK, toluene) sits outside envelope; for those cases switch to a silicone or PTFE-overmoulded housing.
- Q: How does the crystal dome impact artwork tolerance?
  A: The cured epoxy dome acts as a plano-convex lens with ≈ 1.1-1.3× optical magnification at the centre of the dome. This magnifies both the artwork and any print defect, so artwork production lane tolerance is tighter than for a flat-printed ABS fob: Pantone match verification on the printed substrate before pot is recommended, and CMYK raster artwork should be delivered at ≥ 300 dpi to avoid visible print pattern under the dome.
