ASTM D2752

Full Name

ASTM D2752 – Standard Test Methods for Air Permeability of Asbestos Fibers

Scope

These test methods cover the measurement of the relative degree of openness or degree of fiberization of milled asbestos fiber by air permeability instruments:

  1. Method A is the recommended procedure and describes a determination by means of the Rapid Surface Area apparatus. This test method is limited to fibers with an effective surface area in the range from 10 to 250 dm2/g [490 to 12 000 ft2 /lb].

  2. Method B is an alternative procedure and covers the use of the Dyckerhoff apparatus. This test method is limited to fibers within the range from 10 to 600 Dyckerhoff seconds.
