    Abstract： Analyzed are common valve leakage reasons，introduced are Chinese national standards used for valve test and it is pointed out that up to now，there is lack of national standards specially used for valve packing performance test and the existing Chinese national standards used for valve test have low requirement for packing performance. Introduced is API Std 622-2011，Code for Fugacity Test of Process Valve Packing，in which described are fugacity test device，test procedure，corrosion test procedure，material performance test procedure of valve packing and established is an evaluation criteria for valve packing performance. Established is a valve packing product specification by using this standard for reference，which can complement and perfect the current valve test standards and reduce the possibility of valve leakage，and put forward is the suggestion for adoption of API Std 622-2011 standard.
