Aerospace. Hydraulic fluid components. Expression of particulate contamination levels Ingestion-build-224916 NOTE 2: BS EN 15631 Scope This International Standard defines the method of reporting and communicating the contamination (or cleanliness) level of components used in aerospace fluid systems. It also presents a coding system which allows cleanliness data to be reported, both in a shortened manner and in a complete manner, when communicating for reporting contamination level measurement results and for specifying cleanliness requirements.
