Foreword
JB/T 5088 "Internal combustion engines - Spin-on oil filters" is divided into three parts: - Part 1: Specification;
- Part 2: Test method;
- Part 3: Dimensions.
This Part is Part 3 of JB/T 5088.
This Part was drafted in accordance with the rules given in GB/T 1.1-2009. This Part replaces JB/T 5097-1991 "Internal combustion engine spin-on oil filter serial size". Compared with JB/T 5097-1991, the main technical changes are as follows: - ADD the dimensional requirements for the sealing surface; MODIFY the
dimensional requirements for the connecting thread (see 3.1);
- DELETE the provisions on filter element size (2.2 of the 1991 edition); - MODIFY the diameter and length of the filter (see 3.2; 2.4 of the 1991 edition); - MODIFY the dimensions of the sealing ring (see 3.1, 3.2; 2.5 of the 1991 edition); - ADD the technical requirements for bypass valve's opening pressure (see 3.3); - ADD the technical requirements for metal enclosure bottom design (see 3.4). This Part was proposed by China Machinery Industry Federation.
This Part shall be under the jurisdiction of the National Internal Combustion Engine Standardization Technical Committee (SAC/TC l77).
Drafting organizations of this Part: Bengbu Haoye Filter Co., Ltd., Shanghai Internal Combustion Engine Research Institute, Hangzhou Special Paper Co., Ltd., Shanghai Yonghong Auto Parts Co., Ltd., Fuyang Beimu Pulp and Paper Co., Ltd.
