4 试验台
试验台应包括手动液压泵或其他合适技术装置、高压油管、阀门、量程为0kPa~3000kPa或更高
的压力计(见6.6),并加装透明防护罩。试验台示意图如图1所示。
5 试验液
应采用在环境温度下ISO 黏度等级为22且黏度指数(VI)为96的机油(或SAE5W机油)。
6 试验准备和试验程序
6.1 按照推荐的拧紧扭矩安装滤清器。如拧紧扭矩给出了公差,应采用下偏差。滤清器与连接接头的
连接应与产品的安装状况相同。
6.2 将液压泵与滤清器或接头的进口相连接,并在滤清器或接头的出口处接一出油阀。出油阀的出口
应置于整个系统的最高点。
6.3 操作液压泵,将机油泵入系统,直至出油阀出口处观察到机油流出。此时表明全部空气已从系统中排出。
6.4 关闭出油阀,在试验观察者与滤清器之间装上防护罩。
6.5 逐渐升高油压到200kPa,保压约1min,检查滤清器及所有接合处是否渗漏。
注:若已知破裂压力近似值,首次压力可升至已知破裂压力近似值的50%。这样对耐高压滤清器可缩短试验时间,
且不会影响数据质量。
6.6 以每分钟大约345kPa~690kPa的控制压力梯度升高油压,每次压力递增后保压约15s,并检查
滤清器是否渗漏或变形。继续升高油压进行试验,直至达到顾客的规定目标压力值[见7g)]或出现失效。
6.7 将油压降至零。检查滤清器的永久变形和拧紧扭矩。
记录残余拧紧扭矩,如有松动则重新恢复至初始值。
6.8 重新逐渐升高油压,直至达到顾客的规定目标压力值,然后以每分钟大约345kPa~690kPa的控
制压力梯度升高油压,每次压力递增后保压约15s,直至滤清器最终发生失效。
6.9 检查滤清器失效模式的具体形式。

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
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
Discharged.
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.
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
Failure.
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.
b) the name of the laboratory;
c) Filter type (factory model and lot number);
d) test date;
