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

Standard Details

1.1 Quantitative test method to determine the swell volume of plantago insularis (Ovata, Psyllium).

1.2 The purpose of this test method is to provide a means of evaluating the swell volume, millilitres per gram, of psyllium hydrophilic mucilloid.

1.3 The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information only.

1.4 All observed and calculated values shall conform to the guidelines for significant digits and rounding established in Practice D6026.

1.4.1 For purposes of comparing, a measured or calculated value(s) with specified limits, the measured or calculated value(s) shall be rounded to the nearest decimal or significant digits in the specified limits.

1.4.2 The procedures used to specify how data are collected/recorded or calculated, in this standard are regarded as the industry standard. In addition, they are representative of the significant digits that generally should be retained. The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user's objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations. It is beyond the scope of this standard to consider significant digits used in analysis methods for engineering design.

1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
