Bubble Point Testing
F316: Standard Test Methods for Pore Size Characteristics of Membrane Filters by Bubble Point and Mean Flow Pore Test (current)
Published by ASTM Subcommittee D19.08 for Membranes and Ion Exchange Materials, under Committee D19 for Water, effective 1970

The Scope specifically states that this test method is to be used for "membrane" filters (typically as related to water) and for 0.1 up to 15.0 micrometer pore sizes. Accordingly, it is technically not applicable to bubble point testing E2814 specifications, and which commonly range from about 3 to 300 micrometer pore diameter.
ARP901: Aerospace Recommended Practice, Bubble Point Test Method (current)
Published by SAE International, effective 1968

This test method is very comprehensive in reviewing bubble point physics, correcting for immersion depth and temperature, and concludes suggesting a tortuosity factor of 207, which some may consider controversial. It is widely referenced.
