ISO/DIS 23369

Hydraulic fluid power — Multi-pass method of evaluating filtration performance of a filter element under cyclic flow conditions.

At the same time, we still adhere to the following standards in the production process of hydraulic filter.

ISO 2941:2009

Hydraulic fluid power — Filter elements — Verification of collapse/burst pressure rating.

ISO 2942:2018

Hydraulic fluid power — Filter elements — Verification of fabrication integrity and determination of the first bubble point.

ISO 2943:1998

Hydraulic fluid power — Filter elements — Verification of material compatibility with fluids.

ISO 3723:2015

Hydraulic fluid power — Filter elements — Method for end load test.

ISO 3724:2007

Hydraulic fluid power — Filter elements — Determination of resistance to flow fatigue using particulate contaminant.

ISO 3968:2017

Hydraulic fluid power — Filters — Evaluation of differential pressure versus flow.

ISO 4572:1981

Hydraulic fluid power — Filters — Multi-pass method for evaluating filtration performance.

In order to refer to scientific data in testing, we have purchased the following related testing equipment：
