S0989 - Tinius Olsen – ASTM C1161-A.

Articulated 4 Point Bend Test for Ceramic Samples.

Used for testing the smallest ceramic samples 1.5mm x 2.0mm x 20mm. The test calls for articulated anvils that are free to move as the sample deforms. The problem is how to hold the anvils in place before loading the sample. The answer is it’s all done by magnets. The anvil is attracted towards the end of the bar magnet. The magnets are positioned so that the anvil will return to the start position as soon as load is removed. In case you loose the odd one, we supply a bag of spares!
