Code: peroxide_value

Metric: peroxide value

Default value: no more

Metric value dimension: mmol (½O)/kg

Note on the metric dimension: The peroxide values ​​is usually expressed in milliequivalents (meq) of active oxygen per kilogram of oil, but it may also be expressed (in SI units) as millimoles (mmol) of active oxygen per kilogram of oil. The values ​​expressed in millimoles of active oxygen per kilogram is half that expressed in milliequivalents of active oxygen per kilogram. Multiplication of the peroxide values ​​(meq of active oxygen per kg) by the equivalent mass of oxygen (equivalent 8) gives the milligrams of active oxygen per kilogram of oil. From meq/kg to mmol/L mmol/L = meq/kg · mmol/2 meq · 1 kg/1000 g · g/L (density) · 1000 mL/L.
