《GB/T 8243.14-2020内燃机全流式机油滤清器试验方法 第14部分：复合材料滤清器的冷起动模拟和液压脉冲耐久试验》由TC177（全国内燃机标准化技术委员会）归口，主管部门为中国机械工业联合会。
Introduction
Analysis of the core content of the standard
This part specifies the performance verification method of composite oil filters under extreme working conditions, mainly including:
- Cold start simulation test: simulates engine starting conditions in the temperature range of -20℃~130℃
- Hydraulic pulse durability test: verifies the ability of the filter housing to withstand periodic pressure fluctuations
Key technical requirements
| Test type | Pressure range(kPa) | Number of cycles | Temperature conditions |
|---|---|---|---|
| Lightweight spin-on | 1000-1600 | 1000-5000 | -20℃~130℃ |
| Heavy Duty Spin-On | 1300-1600 | 3000-5000 | |
| Removable | 500-900 | 25000-75000 |
Test Equipment and Implementation Points
Typical Test Case
When verifying Class A products, a composite filter manufacturer found that:
- Under 1000kPa pulse pressure, micro cracks appeared at the shell weld
- After optimizing the glass fiber content ratio, the number of cycles increased to 120% of the standard value
Standard Evolution Analysis
Compared with ISO4548-14:2016, this standard adds:
- Special test requirements for composite shells
- Precise control index of pulse waveform rise time
- Test fluid compatibility judgment criteria
Implementation Recommendations
Testing Agency Operation Guide
- The pressure sensor should be directly installed in the specimen cavity
- The system preheating time shall not be less than 4 hours
- The cycle frequency shall be controlled within the range of 0.5-2Hz
