API 6D Leakage Rate

Hi folks,

Since our construction team found some dropped oil from the valve actuator gearbox during hydrotest of the piping system, and they consider the leakage was comes from the valve's seal and/or seat. Please somebody help me what is the acceptable leakage rate for API 6D metal to metal ball valve which mentioned on ISO 5208 Rate D.

Thanks,
Yan Suryana
