1.1 This test method can be used to determine the grease particle capture efficiency of components and systems used in commercial kitchens to capture grease effluent prior to entering the exhaust duct. The results can be used to select a filter system best suited to a particular application.

1.2 This test method is applicable to filter components and systems. The performance information is obtained for new or clean filters and does not include the performance of used or loaded filters.

1.3 The filter can be evaluated with respect to the following (where applicable):

1.3.1 Pressure drop as a function of airflow through the filter (10.3), and

1.3.2 Particulate capture efficiency by particle size (10.4).

1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are for information only.

1.5 This test method may involve hazardous materials, operations, and equipment. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
