Introduction
GB/T 8243 specifies the standard test procedure for determining the performance of full-flow oil filters for internal combustion engines. The standard consists of individual parts
Compiled, each part relates to a certain job characteristic.
The whole set of tests provides the necessary information for evaluating the characteristics of the filter, but if the user and the manufacturer reach an agreement, each test can be separated
get on.
Test method for full-flow oil filter of internal combustion engine
Part 12.Filtration efficiency and ash capacity of particle counting method
1 Scope
This part of GB/T 8243 stipulates that under continuous injection test impurity conditions, the online particle counting method is used for multiple passes.
The filter test is used to evaluate the performance of the full-flow oil filter for internal combustion engines. The scope of this part is limited to steady-state conditions, and the flow rate does not fluctuate
in the case of.
This section applies to the determination of filter dust holding capacity, particle removal characteristics and differential pressure.
This section applies to filter elements with a filtration efficiency of less than 99% for particles larger than 10μm.
Note. In order to cover the entire flow range of 2L/min~600L/min, it may be necessary to build several test flow loops on a test bench, or
Inspector.
