SIL Calculator is a tool designed to calculate the safety integrity level (SIL) of safety instrumented functions (SIF) for SIL verification using fault tree analysis. This tool will be 100% web based allowing direct access to data anywhere anytime.


  • Two level voting (e.g. 1oo2 and 2oo3 into a 1oo2)
  • Computes SIL, RRF, PFDavg
  • Optimise proof test frequnecy
  • Multiple proof test coverage and frequencies

Estimated Alpha Release: November 2012
