Flexural Strength


Recording Beam Testers

Record of Loading to prove application within specified rates and to show maximum applied load.
Reduced Discrepancies & Cost because operator needs no technical experience and little instruction or practice.
Load Application at a uniform rate and avoiding shock as now required under most standards.
1%Accuracies with minimum possibilities for human error.
Minimum Maintenance & Injury Risks through built-in durability and design features.
Full Compliance with current methods, including ASTM C78. Crosshead Assembly(Support Blocks) - One cross-head bearing block has a rod pivot, the other a ball pivot. Threaded sprockets integrate the crossheads with the all-thread tie rods. ...


Third-Point Loading- TCM Recording Charts, PKG/400

The loading chart has two rates of applied load spirals dependent on the depth of the specimen in order to constantly increase the extreme fiber stress optimally between 862 and 1206 kPa/min. One loading spiral (SI) is 7500 N/min for depths of specimen between 149.4 and 153.4 mm (1016 KPa/min for nominal 150 x 150 mm cross-sections). The second loading spiral (IP) is 7865.79 N/min for depths of specimen between 151.5 and 155.5 mm (1016 kPa/min for nominal 152.4 x 152.4 mm, i.e. 6x6 inch., cross-sections). Both spirals indicate maximum applied load (P) when rupture occurrs directly in Newtons.] Calculate the moduls of rupture (R) using formulas in the standard test method, typically;
