Cleanliness Analysis According to VDA 19.1 & ISO-16232

Part 1

Standardized Analysis of Component Cleanliness

Every standardized cleanliness analysis consists of three steps (see figure). First, the residual contaminant particles are extracted from the component surface using a liquid. In the second step, the liquid is filtered and the particles are collected onto a filter membrane. In the third and final step, the membrane is analyzed to determine the mass, number, size and type of particles.
