BFM202 – Soap Test

Biodiesel should be free of residual soaps to meet ASTM 6751 specifications. ASTM 6751 sets the limit for free glycerin and total glycerin in the biodiesel sample. Biodiesel with excess Free Glycerin will be to viscous, may settle to the bottom of storage tanks, and attract moisture. Biodiesel with excess Total Glycerin can lead to carbon build-up and diesel engines with fuel system fouling issues. Qualitative indicator tests provide an assay for biodiesel glycerol content. View the video how to test biodiesel for soap content.

Safety specific to this lab: Review precautions for all chemicals, wear safety goggles and gloves, ensure proper ventilation, and control or eliminate possible ignition sources.
