Analysis and Conclusion of the Test
The results of the comparative test shows that the filtration efficiency and service life of the oil filter element which is made of ultra-high molecular weight composite meet the technical requirements of standard JB/T 5087-91. The element can reduce the friction couple's abrasion and the result of this testing is superior to the paper one. The tested filter functioned normally during the 100 hours' reliable re-testing.
Note The testing standards are with reference to JB/T 5087-91 China.
