Pressure readings and observations made while testing are helpful in determining whether a filter is clean and usable. Such tests include:

	Bump Test
	Visual Test
	Bubble Point Test
	Wetted Air Flow Test
	Dry Air Permeability Test
	Internal Inspection with Videoscope

The validity of the data generated by these tests is related to how the testing is performed. Proper test methods and procedures are essential in creating meaningful data.

CFI has equipment set up to perform the above tests on all standard filter elements. We often, however, are challenged by unusual filter sizes and configuration, which require our in-house engineering and fabrication services.

Reporting Summary

Reporting testing values can be performed in various ways. Typical reports include:

	Comments
	Test Values
	Set Numbers
	Micron Ratings
	Pass-Fail Criteria
	Filter Serial Number
	Bubble Point Values
	Statistics for the Set
	Flow Test Pressures
	Number of Cleaning Cycles

Reporting is customized for each customer to provide information and format desired for each application.
