Formula for derice pounds per square inch tensile strength:
(3 * F * S) / (2 * W * D * D)
Where F = Force in lbs necessary to break the bar
S = Span in inches
W = Width of bar at break in inches
D = Depth of bar at break in inches
See DSRN test notes for more information.
Round or square fired bars are subject to a force that tests their tensile strength. The strength can be calculated from the force and the dimensions of the cross section where the break occurred.
WID - Width (V)
DEP - Depth (V)
SPAN - Span (V)
TMP - Firing Temperature (V)
VAL - Value (V)
