This document replaces GB/T 8243.6-2017 Methods of test for full-flow lubricating oil

filters for internal combustion engines - Part 6.Static burst pressure test. Compared

with GB/T 8243.6-2017, in addition to structural adjustments and editorial changes, the

main technical changes are as follows.

a) The provision that other lubricating oil temperatures may be used in the test

fluid has been added (see Chapter 5);

b) The provisions on tightening rotation angle have been added [see 6.1.1, 6.1.8,

6.1.9, and f) and h) in Chapter 7];
