Fugitive Emissions Testing on Pipeline and Wellhead Equipment Used in the Petroleum and Natural Gas Industries

CDN $108.00

This publication was last reviewed and confirmed in 2026.

Description

This standard identifies the requirements for testing of valves and chokes where fugitive emission of methane at pressures up to 138.0 MPa (20,000 psi) is a consideration. Factors affecting fugitive emissions performance that are considered by this standard include temperature, pressure, and thermal and mechanical cycling. Throughbore
valve leakage is outside the scope of this document.

This standard is written for testing of a complete valve assembly and not for individual components and/or parts.
