Class 1 (1E) and Class II (seismic only) nuclear-rated bargraphs are functionally identical to their commercially-rated counterparts but they include the following:

  • Software for the Class I bargraphs has been verified and validated (V&V) to IEEE-, 1993 standards.
  • EMI/RFI testing has been performed to current Nuclear Utility requirements.
  • Mild-environment qualification to IEEE-323-1983 and IEEE-344-1987

AMETEK's VIS Quality programs include 10CFR50. Appendix B, audited by a member of NUPIC.

Use the following table to associate commercial bargraphs with their Class I and Class II counterparts.
