The component cleanliness testing service primarily uses a flushing/pressure rinse method for the removal of contamination from components, hoses, pipes, injectors, pumps, valves, radiators, engine blocks, cylinder heads, cranksahfts and manifolds. The flushing liquid is drawn through a membrane filter and analysed with a Leica microscope to count particles and weighed to give a gravimetric weight in mg.
The microscope analysis identifies the quantity of particles in different size classes including longest particle and fibres according to the applicable test standards applied. Results are recorded and sent to the customer in a report as per the template below. The microscope system can categorise particles into reflective and non-reflective to give an indication on the ratio of metallic and non-metallic particles.
