ASTM does not give any warranty express or r128 or make any representation that the contents of this abstract are accurate, complete or up to date. Maximum pore diameter is determined by immersing the filter in a suitable test liquid and applying air pressure until the first bubble of air passes through the filter.

This test method establishes a uniform designation for maximum pore diameter and also provides a means of detecting ast, measuring changes which occur through continued use. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend. Historical Version s – view previous versions of standard.

No further reproductions authorized. Summary of Test Method 1. 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.

The automated pressure ramping profile generates the Dynamic Bubble Point pressure that is used to determine Pore Diameter of stainless steel and ceramic diffusers. ASTM grants you a license as follows: Content only available by subscription. Furthermore, aetm traditional analog flow meter is replaced by a digital mass flow meter that directly interacts with the software.
