and/or soil together.
3. Summary of Test Method
3.1 Product specimen is taken and weighed, saturated and measured. The mucilloid content is expressed as a percent.
4. Significance and Use
4.1 The meaning of the test is related to the manufacturing and end use of the material, to determine characteristics of products.
5. Apparatus
5.1 Electronic Gram Scale or Balance Scale, minimum accuracy 0.0000.1 gms.
5.2 Graduated 50.0 mL Glass Cylinder , with ground glass stopper.
5.3 Weighting Boat.
5.4 60 Minute Timer, graduated in one minute intervals.
6. Sampling, Test Specimens, and Test Units
6.1 Prepare specimen by separating 3.0 g of plantago insularis (Ovata, Psyllium) used as a tackifier from an undamaged bag
1 1 1
by taking ⁄3 from the top of the bag, ⁄3 from the middle of the bag and ⁄3 from the bottom of the bag.
7. Procedure
7.1 Weigh weighting boat and place 1.0 g of the plantago insularis (Ovata, Psyllium) used as a tackifier specimen in the
weighting boat.
7.2 Transfer the sample in the weighting boat quantitatively to the graduated cylinder.
