Note: The subtracted number 68 in the column of the weight to be added in the table represents the
weight of the load bar + tray + indenter (or indenter) + sensor axis. The calculation of the weight to be
added is based on g = 9.81 m/s2 calculation.
For sample sizes not in the table, the required load can be calculated by the following formula:
F=2 ×δ×b × h × h / (3 × L) ........................(1)
F1 = F × 1000 / 9.81 – R ....................................(2)
In the formula: F—the load to be applied to the sample, in N
F1—The mass to be added with weight, unit g
δ－Standard bending normal stress (A method 1.80MPa; B method 0.45MPa; C method 8.0MPa)
b—sample width, unit: mm
h—sample height, unit: mm
L—The distance between two pivots, 100mm/64mm
R—load bar weight + pallet weight + pressure needle (indenter) + sensor axis (70g)
If there are two sets of sample holders, check the two deformations corresponding to the installed
samples, and click "Start Test" to start temperature control;
