Comprehensive Filter Testing Standards

To ensure the reliability and scientific integrity of hydraulic filter production, we strictly follow the following internationally recognized test standards:

Structural Integrity Test

BS ISO 2942:2018 / GB/T 14041.1-2007 — Verification of fabrication integrity and determination of the first bubble point.

Differential Pressure vs. Flow Test

BS ISO 3968:2017 / GB/T 17486-2006 — Evaluation of differential pressure versus flow characteristics.

Collapse/Burst Pressure Rating Test

ISO 2941:2009 / GB/T 14041.3-2010 — Verification of collapse/burst pressure rating.

Flow Fatigue Resistance Test

ISO 3724:2007 / GB/T 17488-2008 — Determination of resistance to flow fatigue using particulate contaminant.

Material Compatibility Test

ISO 2943:1998 / GB/T 14041.2-2007 — Verification of material compatibility with fluids.

Rated End Load Test

ISO 3723:2015 / GB/T 14041.4-2019 — Method for rated end load test.

Multi-pass Filtration Performance Test

BS ISO 16889:2022 / GB/T 18853-2015 — Multi-pass method for evaluating filtration performance of a filter element.

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

Capillary flow pore size meter、Filter material air permeability tester、Filter material burst tester、XRF portable analyzer、Full-automatic vision measuring system.
