摘要

The correlation of surface cleanliness defined by MIL-STD-1246B and the resulting geometric obscuration, or percent area coverage (PAC), was rigorously calculated by Ma, Fong, and Lee in 1989. This correlation is effective for surfaces that follow a distribution of particle sizes defined by a slope of -0.926. This evaluation extends the correlation of surface cleanliness level and PAC to a more generalized format, compatible with alternative distribution slopes. In addition, an attempt at determining the distribution slope from a defined slope and cleanliness level is presented.
