Field Test Report Template: The Complete Data Checklist
Part of the Testing & Analysis: The Complete Guide — this article is one of the detailed pages in the guide.
Direct answer: A field test report is only usable for engineering decisions when it records the conditions, not just the headline result. A conversion number without flow, temperature, O₂, moisture, SO₂ and catalyst volume cannot be checked, compared or repeated. This page defines the complete field list and provides a blank template for a customer to fill in.
Why most field reports fail
The single most common weakness — visible across published case records, including those in the Evidence Registry — is missing operating conditions. A result such as "CO reduced from 1,499 ppm to 18 ppm" is arithmetic on two numbers; it becomes engineering evidence only when the conditions behind those numbers are recorded.
The complete field list
| Field | Unit | Why it matters |
|---|---|---|
| Gas flow rate | Nm³/h | Sets space velocity and mass balance |
| Operating temperature | °C | Confirms the catalyst is above light-off / in window |
| O₂ concentration | % vol | Reaction stoich and CEMS normalization |
| Humidity / moisture | % or g/Nm³ | Adsorbent capacity and catalyst competition |
| SO₂ concentration | mg/Nm³ | Poison / acid-gas load |
| Dust / particulate | mg/Nm³ | Erosion and blinding risk |
| Inlet concentration (each pollutant) | ppm or mg/Nm³ | The starting point |
| Outlet concentration (each pollutant) | ppm or mg/Nm³ | The result |
| Space velocity (GHSV) | h⁻¹ | Normalizes the result to reactor size |
| Catalyst / adsorbent volume | m³ | Required to compute space velocity |
| Reactor dimensions | m | Bed geometry, face velocity |
| Continuous operating time | h | Stability, not a snapshot |
| Test instrument | model/method | Traceability and accuracy |
| Testing organization | name | Independence and method |
| Test date | date | Recency and trend baseline |
What a report must also say about method
- Sampling location and traverse — where in the duct the sample was taken.
- Analysis method — reference method or analyzer type, calibration status.
- Normalization — whether values are dry, wet, at reference O₂, or as-measured.
- Load condition — stable load, turndown, or transient.

How this connects to the Evidence Registry
When a field test is later cited on a product or case page, the recorded fields above determine its verification status in the Evidence Registry. A test with the full field list recorded is Confirmed; a test that records only inlet/outlet pairs is Partially recorded and cannot be generalized beyond its stated application. The registry applies this distinction to every documented result.
Manufacturer perspective
We provide this checklist to customers before a trial so the test is complete the first time. Retro-fitting missing conditions after the fact is rarely possible — the sample is gone, the load has changed, the instrument has moved. Completeness is a before-the-test discipline.
