Anotácia textu normy API STD 6Y :

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. Through-bore 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. See more
