Public
  totalDissolvedCombustibleGas
Details:
Notes: Total dissolved combustible gas concentration (in ppm, specifically in microlitre/litre). Calculated by adding the ppm of combustible gasses: hydrogen (H2), methane (CH4), ethane (C2H6), ethylene (C2H4), acetylene (C2H2), and carbon monoxide (CO).<br/>

  estimatedSafeHandlingLimit
Details:
Notes: Estimated Safe Handling Limit (ESHL) (in percent). Estimated safe handling limit is an estimate of the lower flammability limit (LFL) of the combustible gas mixture which the dissolved gas in the oil would give off by the oil if exposed to air. <br/>Expressed in percent like the equivalent total combustible gas percent, it is calculated from the dissolved-gas concentrations, the oil sample temperature, and the lower flammability limits of the individual combustible gases. <br/>
