Previously mean pore throat size and permeability were roughly determined

using air permeameter technology. Recent research funded by the American

Petroleum Institute (API) used the latest Mercury Injection Capillary pressure

technology to determine these characteristics. This new procedure found that

the manufacturing process does not allow for absolute consistency between

ceramic batches, but after numerous tests over several years, the final results

was statistically pretty close. Even though the ceramic filters are the same

filters that have been provided for years, the new API method for determining

mean pore throat size and permeability have resulted in new and improved

specifications as outlined in the chart. All results and all orders should be

based upon the information under the “New Mercury” column in the chart.

All ceramic disks must be soaked in the base fluid being tested for at least 30

minutes prior to usage. Failure to do so will result in premature and excessive

plugging of the pores within the disks, giving erroneous results. Laboratories

often will perpetually soak disks in the base fluid.
