The test bench is mainly used for testing the performance of hydraulic filters according to the ISO16889:2018, ISO19438:2003, ISO4548:2017 and ISO3968-12:2017. The test bench is full automatically controlled by computer, the screen can display the flow chart and all the test parameters. All the data will be saved in order automatically by the computer. Data handling and generate reports according to the ISO16889:2018, ISO19438:2003, ISO4548:2017 and ISO3968-12:2017 are included.

The following test can be made with the test bench:

• Multi-pass method for evaluating filtration performance of oil filters and fuel filters
• Multi-pass method for evaluating filtration performance of a flat sheet filter media (round area of 200 cm²)
• Single-pass method for evaluating initial filtration efficiency of fuel filters
• Particle retention ability and contamination holding capacity
• Differential pressure characteristics of the filter

As mentioned, the test bench allows to execute test in accordance with:

• ISO16889:2018 Hydraulic fluid power – Filters – Multipass method for evaluating filtration performance of a filter element
• ISO19438:2003 Diesel fuel and petrol filters for internal combustion engines – Filtration efficiency using particle counting and contaminant retention capacity
• ISO4548-12:2017 Methods of test for full-flow lubricating oil filters for internal combustion engines Part 12: Filtration efficiency using particle counting and contaminant retention capacity
• ISO3968:2017 Hydraulic fluid power – Filters – Evaluation of differential pressure versus flow

 

Evaluable variables:

• Element pressure drop
• DHC (Dirt Holding Capacity)
• Element filtration efficiency (β value)
