Automatic Analyser for Component Cleanliness

The particle measuring system AACC (Automatic Analyser for Component Cleanliness) has been developed by Pamas (Germany) for production control. This system measures the particle contamination of components according to the standard ISO 16232.

The precision of mechanical parts is essential for quality, and therefore manufacturers, contractors and suppliers are all asking for production control and for parts-cleaning. The high demand on manufacturing precision requires the absolute cleanliness of the components. Industrial parts-cleaning assures the function, quality and life time of the components in process. The standard ISO 16232 defines the procedure and the conditions, which are required to analyse the remaining particle contamination on components.

The particle counter manufacturer Pamas, has developed the modern particle measurement system AACC in order to improve the effectiveness of industrial partscleaning and to fulfill the requirements of ISO 16232 at the same time.

AACC automates the proceedings of conventional membrane filtration to a large extent and reduces the required manual labour to a minimum. The newly developed system measures the remaining particle contamination on components and offers direct optical particle counting combined with the option to use conventional membrane filtration as well.

Contrary to the conventional filter analysis, the direct optical particle analysis works almost automatically. Manual labour is required only for rinsing the spray cabinet and for extracting the particles out of the components. As a first step, the components are rinsed in the spray cabinet and the used and contaminated cleaning liquid is stored in a container. A short vacuum treatment afterwards removes gas bubbles from the liquid. After this treatment, the particle counting starts by optional means of pressure. The particle measurement works automatically. It is possible to operate a gravimetric or microscopic
membrane filtration analysis at the same time.
