Of the various methods and standards used for testing of valves for low fugitive emission application, which are most appropriate for a valve? Is the decision based on the valve type or design? Is it based on the geographic market the valves are being sold into? Is it based on application? With ISO 15848-1, which of the various tightness, endurance and temperature classes should be applied?
In his article, Stan Allen & Vanessa Mertes of Bray International provide guidelines for valve manufacturers, engineering companies and end users on which standard to apply, and when and how the different techniques of the standards should be applied. Drivers for testing, such as the environmental laws, industry standards, end user specifications and responsibility are the basis for the development of the valve test standards and impact the type and standard method that is applied.
