How can hose cleanliness be described? The ‘textbook’ answer suggests that hose cleanliness is the analytical and statistical measure of the solid particle contamination present in a sample hose assembly or its individual components. It is typically given in a certain tolerance allowed per size or count.
While this is a very straightforward concept, in practice the ‘amount’ of contamination allowed in supplied hose assemblies are commonly defined by industry standards or internal standards. It is therefore important to understand the different approaches to determining the degree of contamination, the methods to mitigate the risk of contaminates, and how to achieve the required cleanliness levels expected by the customer.
