Committee F21 on Filtration was dissolved at the ASTM Board of Directors meeting last spring due to lack of activity. ASTM Committees are sought to assume jurisdiction of Committee F21’s 12 remaining standards that support liquid and gas filtration systems, media, and equipment used by the pharmaceutical and petrochemicals industries. Interested parties should contact ASTM Staff Manger Bruce Noe at the number below.

When Committee F21 closed, several standards were transferred to Committee D22 on Sampling and Analysis of Atmospheres, and one standard was transferred to Committee D19 on Water. The following standards need adoption, review, and balloting:

• F 301, Standard Practice for Open Bottle Tap Sampling of Liquid Streams;
• F 661, Standard Practice for Particle Count and Size Distribution Measurement in Batch Samples and Filter Evaluation Using an Optical Particle Counter;
• F 662, Standard Test Method for Measurement of Particle Count and Size Distribution in Batch Samples for Filter Evaluation Using an Electrical Resistance Particle Counter;
• F 795, Standard Practice for Determining the Performance of a Filter Medium Employing a Single-Pass, Constant-Pressure, Liquid Test;
• F 796, Standard Practice for Determining the Performance of a Filter Medium Employing a Single-Pass, Constant-Pressure, Liquid Test;
• F 797, Standard Practice for Determining the Performance of a Filter Medium Employing a Multipass, Constant-Rate, Liquid Test;
• F 838, Standard Test Method for Determining Bacterial Retention of Membrane Filters Utilized for Liquid Filtration;
• F 902, Standard Practice for Calculating the Average Circular-Capillary-Equivalent Pore Diameter in Filter Media from Measurements of Porosity and Permeability;
• F 1013, Standard Practice for Determining the Performance of a Liquid/Liquid Separator System Employing a Single-Pass, Constant-Rate, Non-Solids Test;
• F 1067, Standard Test Method for Determining the Performance of a Petroleum Product Filter Cartridge Using a Single-Pass Constant Rate Procedure;
• F 1170, Standard Practice for Determining the Performance of a Filter Medium Using Water and Siliceous Particles; and
• F 1368, Standard Test Method for Determining the Sieving Performance of a Fluid Filter Medium Employing an Aqueous Suspension of Microspheres and a Spectrophotometer.

Standards that are not transferred will be withdrawn by the Committee on Standards. Contact Staff Manager Bruce Noe, ASTM (610/832-9719; fax: 610/ 832-9666). //
