Overview of Stack Emission Monitoring

Tested by: NABL-accredited partner lab
Regulation: EP Rules & IS 11255
Typical turnaround: 5–7 days after sampling
Sampling: On-site sampling at the stack

Boilers, thermic fluid heaters, furnaces, DG sets, incinerators and process vents all have emission limits, set by the Environment (Protection) Rules and your consent to operate. Monitoring follows the IS 11255 series and CPCB guidelines, with isokinetic sampling so that the dust collected represents the gas flowing up the stack.

The team needs a sampling port and a safe platform at the right height on the stack. Results are used for consent compliance and renewal, for checking bag filters and scrubbers, and to cross-check online continuous emission monitoring systems (OCEMS), which CPCB requires for highly polluting industries.

How we handle Stack Emission Monitoring

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
Particulate matter	Isokinetic sampling
Sulphur dioxide and oxides of nitrogen	From fuel combustion
Carbon monoxide and oxygen	Combustion efficiency
HCl, chlorine, ammonia, acid mist	Process-specific pollutants
Heavy metals	Lead, mercury, cadmium and others for furnaces and incinerators
Velocity, temperature, flow rate	Needed to calculate emission load

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

What do I need ready before the team arrives?

A sampling port of the right size at the correct position on the stack, a safe platform with railings and access, a power point near the platform, and the unit running at normal load during sampling.

Will the Pollution Control Board accept the report?

Monitoring is done by labs accredited by NABL and recognised under the Environment (Protection) Act, which State Pollution Control Boards accept for consent compliance and returns. Some boards keep their own list of approved labs; we check yours before booking.

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.
