Assessment of Nonconforming Levels In Parts Per Million (PPM)(STABILIZED Aug 2015) EIA554_2

This standard is intended to provide a uniform method of determining proportion nonconforming in finished components and to provide a standardized definition of the quality index referred to as PPM. The method used here is primarily directed at components whose production or procured volume is large enough, during some predefined sampling period, to give statistically meaningful information.
