Overview - ISO 11170:2013 (Hydraulic filter elements)

ISO 11170:2013 defines a standardized sequence of tests for verifying the performance characteristics of hydraulic filter elements used in hydraulic fluid power systems. The standard specifies how to check hydraulic, mechanical and separation properties of filter elements using established test methods. It is not intended to qualify a filter for a specific in-service duty or to replicate actual operating conditions - those require a bespoke test protocol that mirrors the intended fluid and service environment. ISO 11170:2013 is applicable to individual fluids or fluid types with similar chemistry.

Key topics and technical requirements

• Scope: Verification sequence covering fabrication integrity, material compatibility, filtration performance, mechanical ratings and flow endurance.
• Test sequence: A logical order of tests to minimize sample use and ensure complete verification. At least three filter elements must be tested and ranked by first bubble point (BP1
