Standard Test Method for Swell Volume of Plantago Insularis (Ovata, Psyllium)

Importancia y uso:

5.1 The meaning of the test is related to the manufacturing and end use of the material, to determine characteristics of products.

5.2 A manufacturer of raw psyllium will base the grade of psyllium produced on multiple properties of which swell volume is one.

5.3 Erosion control contractors and those writing erosion control specifications will use this test method to evaluate the grade of psyllium being used as a hydraulically applied erosion control product. The swell volume will help determine the application rate of psyllium needed to meet the erosion control performance criteria.

Note 1: The quality of the result produced by this standard is dependent on the competence of the personnel performing it and the suitability of the equipment and facility used. Agencies that meet the criteria of Practice D3740 are generally considered capable of competent and objective testing/sampling/inspection. Reliable results depend on many factors; Practice D3740 provides a means of evaluating some, but not all, of those factors.
