Vapor Recovery Testing
Definition - What does Vapor Recovery Testing mean?
Vapor recovery testing is considered to be a part of environmental compliance testing that is regulated by the regulatory authorities of many countries. The most widely accepted standards for testing vapor recovery systems are those set by the Air Resources Board (sometimes called CARB).
Sites are tested for the vapor recovery of volatile organic compounds (VOCs) in their normal operating condition.
Corrosionpedia explains Vapor Recovery Testing
Vapor recovery testing consists of two test stages commonly known as:
- Stage I vapor recovery testing
- Stage II vapor recovery testing
A series of tests are required for facilities that dispense gasoline into motor vehicle fuel tanks or any other pollution-causing instrument or machinery involving petroleum products.
The step-by-step tests are:
- The integrity testing of all pipework including vents, manifolds, vapor return pipes and hoses.
- Integrity testing of fill pipes.
- Leak testing of all valves.
- Performance testing of all valves including pressure vacuum valves, vapor connection point valves and pressure relief valves.
- Performance confirmation of all stage II nozzle pumps.
- Flow rate measurement of vapor returning to a road tanker during filling operations.
- Road tanker testing.
