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.

Copy this block into your own document and fill every field. A field left blank is a data gap that will be questioned later.

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.
