DESCRIPTION
BS 7403-12:2000
This standard BS 7403-12:2000 Full-flow lubricating oil filters for internal combustion engines is classified in these ICS categories:
- 21.260 Lubrication systems
- 27.020 Internal combustion engines
This part of ISO 4548 specifies a multi-pass filtration test with continuous contaminant injection and using the online particle counting method for evaluating the performance of full-flow lubricating oil filters for internal combustion engines.
The test procedure determines the contaminant capacity of a filter, its particulate removal characteristics and differential pressure.
This test is intended for application to filter elements having a rated flow between 4 l/min and 600 l/min and with an efficiency of less than 99 % at a particle size greater than 10 µm.
NOTE Several test flow loops built into one test rig, or several test rigs, would be required to cover the complete flow range of 4 l/min to 600 l/min.
