This SAE Recommended Practice describes laboratory test methods to measure filter performance. Performance includes, but is not limited to, air flow restriction or pressure drop, overall and fractional efficiency, holding capacity for airborne particles, and air filter structural integrity.

This laboratory test method applies to air filters that improve air quality by reducing concentrations of gaseous, odorous, or hazardous components from ambient and/or re-circulated air in vehicle cabins. The test method provides information on pressure drop, as well as gas and/or vapor removal characteristics. The purpose of the test method is to describe and establish test criteria to enable comparisons of filters and filter components that remove or reduce the levels of containment gases or vapors from air streams under specified laboratory conditions.

This water separation section has been established to cover heavy-duty engine intake filter systems. It may also be applicable to some automotive and industrial air inlet systems where water separation is an issue.

The air cleaner test code has been established to cover dry type and oil bath air cleaners used on internal combustion engines and to present a uniform method of determining and reporting air cleaner performance.

The basic performance characteristics of greatest interest are airflow restriction or pressure drop, dust collection efficiency, dust capacity, and air cleaner structural integrity. This test code therefore addresses itself to the measurement of these parameters.

This test code is for laboratory use in determining the operating characteristics of air cleaners. It refers specifically to laboratory testing of oil bath, oil wetted, dry and multistage air cleaners. Other types should follow this recommended practice wherever applicable. Multistage types should be evaluated as a complete assembly although, if desired, a component stage can be tested separately in accordance with its individual type. This code contains alternate procedures and permits prescribing certain specific conditions of a lest. Therefore reported results of tests are not complete unless accompanied by statements, where applicable, of the specific conditions such as: (1) rated air flow, (2) prescribed air flow. (3) steady or variable airflow, (4) fine or coarse dust, (5) amount of (lust, and (6) maximum permissible restriction.
