The uniformity of distribution of pores approaching the 1 This test method is under the jurisdiction of ASTM Committee E on maximum pore size may be observed by gradually increasing Laboratory Apparatus and is the direct responsibility of Subcommittee E Keywords p observed pressure of water, cm water Note 6.

This is calculated by the software program.

The automated pressure ramping profile generates the Dynamic Bubble Point pressure that is used to determine Pore Diameter of stainless steel and ceramic diffusers. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Are you sure you want to empty the cart? This test method establishes a uniform designation for maximum pore diameter and also provides a means of detecting and measuring changes which occur through continued use.

Content only available by subscription. This abstract is a brief summary of the referenced standard. Permeability is determined by measuring the flow of air through the filter when subjected to a pressure differential.


A aztm in parentheses indicates the year of last reapproval. Search book title Xstm keywords for book title search. The surface tension of the liquid creates centimetres. 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. If you like to setup a quick demo, let us know at support madcad. 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.


Other liquids which meet this criterion may be used. It is the 5. Values for surface tension in Table 1 are asgm general guidance only and are approximate; surface tension of the liquid xstm should be determined.

Furthermore, the traditional analog flow meter is replaced by a digital mass flow meter that directly interacts with the software. Please login to your authorized staff account to use this feature.

Ast, D recommends that the diffusers be tested when new and periodically thereafter, preferably after each use. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

This test method covers the determination of maximum pore diameter and permeability of rigid porous filters used in the laboratory for filtration or diffusion.
