The purpose of this standard is to prescribe a laboratory test method for evaluating the filtration capability of filters and filter driers used in liquid lines of refrigeration systems. This laboratory test method evaluates the capability of liquid-line filters and filter driers only for removing and retaining solid particles of a standard test contaminant. The test method may be applied to all hermetic refrigerant liquid-line filters and filter driers up to and including Model 417S (line size 23 mm maximum).
The technique employed in this standard is the one-pass test method. In this test, a clean-up filter is installed downstream of the test sample and is designed to retain and prevent recirculation of most of the contaminant particles that are not collected by the test sample in the first pass. Filter driers have the added capability of removing and retaining certain dissolved contaminants. This standard does not provide measurement of this capability.
