The yield stress resulting from this test was reported as 190.32 Pa.
Figure IV-64: Hand Cream Sample
IV.8.5.3 Example Application: Ketchup
In this example, a name brand ketchup was tested and compared to a store brand ketchup. Visual
examination of both products could distinguish no noticeable differences. Both tests were run
under exactly the same conditions using an HBDV-III Ultra with spindle V-72. See Figure IV-65
for the test set up.
Significant differences between the name brand and the store brand can be characterized by such
a test as shown in Figure IV-66. Both the slope of the stress/strain curves and the yield points are
clearly different.
