Overview of Coal, Coke & Biomass Fuel Testing

Tested by: NABL-accredited partner lab
Regulation: IS 1350 & IS 436
Typical turnaround: 3–5 working days
Sample needed: 2–5 kg, sealed

Coal is priced and graded mainly on its gross calorific value (GCV), and its moisture and ash content decide how much heat you actually get and how much ash you must dispose of. The IS 1350 series covers proximate analysis, calorific value and ultimate analysis, while IS 436 sets out how coal and coke should be sampled, which matters as much as the test.

Biomass pellets and briquettes made from agricultural residue are increasingly used in industrial boilers and for co-firing in thermal power plants under the government’s biomass mission. Buyers test them for calorific value, ash, moisture and chlorine, which affects corrosion and slagging.

What we do for you

Lab and parameter list chosen for your purpose: licence, export, buyer or internal QC
Sampling guidance, and pickup or on-site sampling where needed
One contact who follows up with the lab until the report is issued
Report explained in plain language, with next steps if a result fails

What to send

The lab confirms the exact quantity and packing for your product when we book the test.

Sample

Quantity: 2–5 kg, sealed
Sealed and labelled with the product name, batch number and date
Packed so that it cannot leak or be contaminated in transit

Details to share

Product name, grade and specification sheet
Safety data sheet (SDS)

How we handle Coal, Coke & Biomass Fuel Testing

1
Assessment of requirement
We confirm the standard, the list of tests and how many samples your product needs.
2
Sample collection
We collect the samples from your factory or warehouse, or tell you exactly where to send them.
3
Right lab assigned
We choose an accredited lab (NABL, BIS-recognised or ILAC) that covers your standard and can start soonest.
4
Testing
The lab tests your samples against the standard. We follow up and tell you at once if a test fails.
5
Test report
You receive the signed test report, ready to use for BIS, WPC, CE or your buyer.

What the lab tests

Parameter	Why it is checked
Total and inherent moisture	Affects the usable heat and handling
Ash, volatile matter, fixed carbon	Proximate analysis
Gross calorific value	Main basis for pricing
Sulphur	SO2 emissions and corrosion
Carbon, hydrogen, nitrogen, oxygen	Ultimate analysis for combustion design
Ash fusion temperature and chlorine	Slagging and corrosion risk, especially for biomass

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

Why do my lab results differ from the supplier’s?

Often because of sampling or the basis used to report: as received, air-dried or dry. We report on the basis your contract uses and help set up sampling that both sides accept.

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.
