JB5088--91
This standard specifies the technical requirements, inspection rules and marking, packaging, transportation, storage, etc. of spin-on oil filters for internal combustion engines. This standard applies to spin-on oil filter assemblies (hereinafter referred to as assemblies) with a volume flow rate of less than 50L/min. 2 Reference [Standards

Internal combustion engine paper filter element oil filter assembly test method 3 Technical requirements
3.1 The assembly shall be manufactured according to the product drawings and technical documents approved by the prescribed procedures, and its technical requirements shall comply with the provisions of this standard. 3.2 The elastic material seal in the assembly shall be oil-resistant and moisture-resistant. 3.3 The inner and outer surfaces of the assembly and the metal parts such as the threaded cover plate, the sealing surface plate, and the spring shall be treated with anti-rust, and the surface plating and coating shall be free of rust and peeling.
3.4 ​​The hydraulic pulse fatigue resistance of the assembly is to be tightened on the test bench according to the tightening torque specified by the manufacturer. With the oil pressure peak value of 0.8MPa, after 15,000 pulse cycles, the filter housing should not be deformed, oil leakage is not allowed at the joints, and the parts should not be damaged. The pulse waveform is shown in Appendix A (Supplement).
3.5 The original resistance of the assembly should not be greater than 0.025MPa at the rated volume flow. The rated volume flow is calculated according to formula (1):
Q-0.006.F
Where Q is the rated volume flow, L/min;
0.006 is the coefficient, L/Cmin·(cm)-), and F is the effective filtration area of ​​the filter element, cm.
3.6 The filtration efficiency of the assembly is tested with the standard test impurities of the oil filter. Its original filtration efficiency should not be less than 60%. The particle size distribution of the test impurities is specified in Appendix B (Supplement). ：3.7 The plugging life of the assembly shall not be less than 3h when the pressure drop reaches 0.07MPa. 3.8 The opening pressure of the bypass safety valve in the assembly shall comply with the requirements of the product drawings. 3.9 The bypass safety valve in the assembly shall be tested for sealing performance. When the pressure difference before and after the valve is 0.03MPa lower than the specified opening pressure, the oil leakage shall not exceed 0.2L/min.
3.10 If a check valve is provided in the assembly, its sealing performance shall not exceed 0.1L of oil explosion in 6h under the action of 600±10mm oil column pressure head. 3.11 Under the action of 0.35MPa pressure drop, the center tube of the filter element shall not be deformed, and the filter element shall not have defects such as cracking, perforation, and degumming. 3.12 The assembly shall be tested for high oil theft resistance. After immersion in 135C engine oil for 192h, the filter element shall not be degummed or cracked, and other parts shall not be permanently deformed or partially damaged.
3.13 The static pressure rupture test of the assembly, under the action of 1.5MPa oil pressure, maintain the pressure for 1~5min, the shell should not be damaged and oil leakage. Approved by the Ministry of Machinery and Electronics Industry on July 1, 1991 and implemented on July 1, 1992
JB508891
3.14 The inside of the assembly should be clean, and its cleanliness limit is: the rated volume flow rate is less than 10L/min and should not exceed 3mg·(L/min)-1 vehicle; the rated volume flow rate is greater than or equal to 10L/min and should not exceed 3mg·(L/min)-1. The cleanliness test method shall be in accordance with GB3821. 3.15 The connection screw holes between the assembly and the host shall comply with the provisions of the product drawings. 3.16 There should be no obvious scratches or burrs on the outer surface of the assembly, and the paint surface is not allowed to have defects such as exposed bottom and hanging flow. 3. 17
The test methods for the relevant items in this chapter shall comply with the provisions of JB/T5099. 4 Inspection rules
Each assembly shall be inspected by the quality inspection department of the manufacturer, and a product certificate shall be issued after passing the inspection. 4.2 When the ordering unit samples the quality of the assembly products, it shall be carried out in accordance with the provisions of GB2828, and the qualified quality level AQL value shall be agreed upon by both parties.
5 Marking, packaging, transportation, storage
The assembly shall be marked with the manufacturer's name or factory logo, product name and model, and each assembly shall be packed separately in a paper box, and shall be accompanied by a product certificate and instructions for use and maintenance signed by the inspector. When the assembly leaves the factory, it shall be packed in a dry explosion packaging box lined with moisture-proof material, and ensure that it will not be damaged during the normal transportation. The outer surface of the packaging box should be marked with:
Manufacturer name and address;
Product name and model:
Factory date:
Volume: length × width × height, mm;
Gross weight: kg:
Quantity:
Consignee and address:
"Moisture-proof", "Handle with care"
5.5 The assembly should be stored in a ventilated and dry warehouse. Under normal storage conditions, the manufacturer should ensure that the assembly will not rust within 12 months from the date of shipment. The filter element shall not rot or debond. 2
