The automated pressure ramping profile generates the Dynamic Asmt Point pressure that is used to determine Pore Diameter of stainless steel and ceramic diffusers. Both results are automatically displayed on the computer screen.

No other units of measurement are included in this standard. Content only available by subscription. This abstract is a brief summary of the referenced standard. Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. A superscript epsilon indicates an editorial change since the last revision or reapproval.

It consists of a certified NIST traceable U-tube manometer capable of reading mm of water installed on a wall mountable stainless steel panel, a ml graduated cylinder, a precision regulating valve and a 1 meter length of 8 mm plastic tubing.

It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

This pore diameter is calculated from the surface tension of the test test method establishes a uniform designation for maximum liquid and the applied pressure. For test sticks and candles a rubber stopper with a rubber tubing attached is suitable.

Foam Diffuser Certification Apparatus for ASTM D, D, E

Specifications subject to change without notice. No further reproductions authorized. ASTM D requires the recertification of the diffuser after 10 foam tests. Values for surface tension in Table d128 are for general guidance only and are approximate; surface tension of the liquid used should be determined.

The maximum pore diameter is asm from the surface tension of the test liquid and the applied pressure. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM Headquarters.
