Full Description

ISO 11170:2003 defines a sequence of tests for verifying filter elements. It can be used to check their hydraulic, mechanical and separation characteristics.

ISO 11170:2003 is not intended to qualify a filter for a particular duty or replicate conditions of service. This can only be done by a specific test protocol developed for the purpose, including actual conditions of use (for example the operating fluid).

The procedure in ISO 11170:2003 is applicable to individual fluids, or types of fluids having similar chemistry.
