Full-flow internal combustion engine oil filter test method
Part 6. Static Pressure Bursting Test
1 Scope
This part of GB/T 8243 specifies the ability to determine the static pressure target value of a full-flow oil filter for an internal combustion engine and determine the static pressure resistance.
Degree of magnitude and test method for determining failure mode.
This section does not apply to aviation filters and plastic type filters.

3 Terms and Definitions
The terms and definitions defined by ISO 4548-1 apply to this document.
4 Test bench
Test bench should include manual hydraulic pump or other suitable technical device, high pressure tubing, valves, range 0kPa~3000kPa or higher
Pressure gauge (see 6.6) and install a transparent protective cover. The schematic diagram of the test bench is shown in Figure 1.
5 test solution
The oil with an ISO viscosity class of 22 and a viscosity index (VI) of 96 at ambient temperature (or SAE 5W oil) should be used.
6 Test preparation and test procedures
6.1 Install the filter according to the recommended tightening torque. If the tightening torque gives tolerances, the lower deviation should be used. Filters and fittings
The connection should be the same as the product's installation.
6.2 Connect the hydraulic pump to the inlet of the filter or fitting and connect an outlet valve at the outlet of the filter or fitting. Outlet valve outlet
Should be placed at the highest point of the entire system.
6.3 Operate the hydraulic pump and pump the oil into the system until the outflow of oil is observed at the outlet of the outlet valve. This indicates that all air has been removed from the system
6.4 Close the oil valve and install a protective cover between the test observer and the filter.
6.5 Gradually increase the oil pressure to.200 kPa, maintain the pressure for about 1 minute, and check if the filter and all joints leak.
Note. If an approximate rupture pressure is known, the first pressure may rise to 50% of the approximate value of the known rupture pressure. This reduces the test time for high pressure filters.
And it will not affect the data quality.
6.6 Increase the oil pressure at a controlled pressure gradient of approximately 345kPa to 690kPa per minute, hold the pressure for approximately 15 seconds after each pressure increase, and inspect
If the filter leaks or deforms. Continue to raise the oil pressure to test until the customer's specified target pressure value is reached [see 7g)] or
6.7 Reduce the oil pressure to zero. Check the filter for permanent deformation and tightening torque.
Record the residual tightening torque and return it to its original value if it is loose.
6.8 Re-increase the oil pressure gradually until it reaches the customer's specified target pressure value, then control it at about 345kPa~690kPa per minute.
The pressure gradient is raised to increase the oil pressure. After each pressure increase, the pressure is maintained for about 15 seconds until the filter finally fails.
6.9 Check the specific form of filter failure mode.
7 Test result report
The test report should include at least the following.
a) The number of this part of GB/T 8243, namely GB/T 8243.6;
b) the name of the laboratory;
c) Filter type (factory model and lot number);

j) Burst resistance (see 6.8);
k) Failure mode and failure location.
