Electrical Safety Division Procedures
• Criteria for the Evaluation and Test
of Intrinsically Safe Apparatus and Associated Apparatus (ACRI2001)
  • Digitized MSHA Minimum Ignition Curves (Excel)
    The MSHA minimum ignition curves for methane-air atmospheres were derived from ACRI2001. The hardcopy ignition curves in ACRI2001 remain the official version.
  • Digitized MSHA Minimum Ignition Curves for Inductance at Known Voltage (Excel)
    These MSHA inductive ignition curves were extrapolated from the digitized ACRI2001 Figures 11.2 and 11.3 as an aid for determining acceptability for inductances between 0.1mH and 1000mH.
  • Digitized MSHA 0.3mJ Inductive Ignition Curve (Excel)
    This MSHA inductive ignition curve was derived using the 0.3mJ minimum ignition energy of methane-air atmospheres.
