1 Scope This part of JB/T 1265 1 specifies the terms and definitions, testing items, sampling, preparation andtreatment of samples, testing method and testing report of flter papers used in internal combustionengines. This part is applicable to filter paper used in air filter, oil filter and fuel flter 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 fibrefilter paper and pure non-woven. Filter paper for other filters can refer to this part. 2 Normative references The following referenced documents are indispensable for the application of this document.
