Overview of Biofuel Testing – Ethanol, Biodiesel & CBG

Tested by: NABL-accredited partner lab
Regulation: IS 15464, IS 15607, IS 16087
Typical turnaround: 5–7 working days
Sample needed: 1–2 litres, or a gas cylinder

Under the National Policy on Biofuels, oil marketing companies blend ethanol into petrol and buy biodiesel and compressed biogas (CBG) from producers. Each has a BIS specification: anhydrous ethanol for blending under IS 15464, biodiesel (B100) under IS 15607 and biomethane under IS 16087. Supplies that fail are rejected at the depot.

Distilleries and grain-based ethanol plants test every batch for water content, acidity and methanol. Biodiesel made from used cooking oil, a route FSSAI and the oil companies promote, is checked for ester content, free glycerol and oxidation stability. CBG plants under the SATAT scheme test methane content and impurities before supplying to city gas networks or CBG stations.

What the lab tests

Parameter	Why it is checked
Ethanol: purity, water content, acidity	IS 15464 for blending
Ethanol: methanol and higher alcohols	Impurities that affect engines
Biodiesel: ester content, free and total glycerol	IS 15607 core parameters
Biodiesel: oxidation stability, acid value, water	Storage stability
CBG: methane, CO2, H2S, moisture	IS 16087 for vehicle and pipeline use

The final list depends on your product, its standard and the purpose of testing. We confirm it with you before the sample goes to the lab.

Frequently asked questions

Can used cooking oil be tested before it is turned into biodiesel?

Yes. Free fatty acids, moisture and impurities in used cooking oil decide how much biodiesel it will yield and what pre-treatment it needs, so collectors and plants test it on receipt.

Which standard is the product tested against?

The Indian Standard, international method or buyer specification that fits your purpose. We confirm it with you before the sample goes to the lab, and the report states the method used for each parameter.

Who carries out the testing?

Instacertify’s partner laboratories, accredited by NABL to ISO/IEC 17025 for the parameters on your report. We choose the lab, arrange the sample, follow up until the report is issued and explain the results to you.
