Safety-Related (1E) Bargraphs are functionally identical to their commercial counterparts but they include the following:

  • Software verified and validated (V&V) to IEEE-, 1993 standards
  • EMI/RFI testing has been performed to current industry requirements
  • Mild-environment qualification to IEEE-323-1983 and IEEE-344-1987 

Use the following table to associate commercial Bargraphs with their Safety-Related (1E) and Seismically Qualified counterparts.
