Fugitive Emissions Testing

Helping to Reduce Emissions on a Global Scale

With continued pressure from Governments and environmental bodies for companies to operate in the most efficient and environmentally-friendly ways, fugitive emissions testing is becoming increasingly important.  All our testing is carried out in accordance with ISO 15848 or Shell SPE 77/312 and 77/300 under the most stringent safety conditions.

Fugitive emissions testing is designed to identify leakage in critical components using helium as the primary trace gas with a helium mass spectrometer measuring any leakages.

Why use Helium in Fugitive Emissions Testing?

  • It provides the most sensitive and up-to-date method of testing
  • Helium is a safe and inert gas
  • Helium is a very searching gas and therefore readily penetrates minute leaks
  • A proven technology that simulates live conditions
  • No contamination of the atmosphere due to helium being non-toxic, non-hazardous and non-destructive

Fugitive Emissions Testing Capabilities:

  • Production test: Normally carried out at ambient temperature and involves cycling the component during the test (in accordance to ISO 15848-2 or Shell SPE 77/312)
  • Proof test: Temperatures are elevated and reduced for type test approval (in accordance with ISO 15848-1 or Shell 77/300)

Typical Components for Fugitive Emissions Testing: Valves (including ball, gate, globe, check, choke, butterfly, relief), Valve Bodies, Flanges and Process Instrumentation.
