Filter Sealing: Tested under pressure of 0.8 MPa in 30 min. When the filter house & cover are sealed, there should be no leakage. (Air tested allowed) – Sampling 10%.
Dimensional tolerance: According to general dimensions
Appearance: No visible flaws
Weight: Not lighter than normal 10%
6. Testing Inspection Classification
Type test (Samples not less than 3pcs.) and Factory test (Alternate visual and air measurements)
7. Inspection decision rule
The oil filter that meets the requirements of all inspection items is judged to pass the factory inspection; if the oil filter does not meet the requirements of the casting inspection, it is judged that the batch of oil filters is unqualified. the inspection of other items, if there is an oil filter that does not meet the requirements, is allowed to return for repair. After the re-inspection, if the re-inspection meets the requirements, the oil filter will be judged to pass the factory inspection; if the re-inspection still does not meet the requirements, the oil filter will be judged to be unqualified.
