Martechnic®’s Remark: Fundamental Differences of IRON CHECK E Measuring Method

Total iron concentration in cylinder drain oil (CDO) along with remaining base number remains one of the key parameters to be measured and regularly monitored when performing used engine oil analysis. It is important to differentiate between various measuring methods regarding laboratory analysis and on-site testing with portable testing equipment. Each measuring method may vary profoundly and deliver different test results. A comparison between the obtained values originating from different measuring methods may lead to incorrect evaluation of total iron content and /or result in distorted information of actual wear condition of two-strokes diesel engines.

As a consequence, Martechnic^® has prepared a commentary on its IRON CHECK E measuring method based on chemical determination of total iron content. The commentary is aimed to clarify the principal differences of the IRON CHECK E as an on-site testing method to most commonly used laboratory analysis methods and to explain the inapplicability of direct comparison between the obtained test results.
