1 Scope
This part of jB/T 12651 specifies the terms and definitions, classification, technical requirement, testmethod, inspection rule, sign, packaging, transport and storage of filter paper used in internalcombustion engine.
This part is appli cable to filter papers used in air filter, oil filter and fuel filter for internal combustionengines, which are abbreviated as air filter, paper, oil filter paper and fuel filter paper respectively, andare collectively referred to as filter paper. This part doesn't apply to crinkling paper, pure glass fibresfilter paper and pure non-woven. Filter paper for other filters can refer to this part.

4 Classification
4.1 According to the fluid types in the filtration process, filter papers are classified into air filter paper,oil filter paper and fuel filter paper.
4.2 According to the resin treatmenit, filter papers are classified into cured flter paper and non-curedfilter paper.
4.3 According to the shapes, flter papers are classified into fluted filter paper and flat filter paper.
4.4 According to the fame retardancy, air filter papers are classifed into fire-retardant filter paper andnon-fre-retardant filter paper.
4.5 According to the lifetime, oil filter papers are classified into long lifetime oil filter paper and generalfilter paper.
4.6 According to the fltration efficiency, fuel filter papers are classified into high eficiency fuel filter
