The Testing Times

Used for testing reinforcing bars or reinforcement bar ( Rebar ) for the construction industry. The way that mass produced R ebar is made requires test for consistency throughout a products manufacture life cycle. The sample is placed on the lower support rollers, then bent to a certain angle (depending upon test). It is then treated (heated to a specific temprature) and then rebent, back to straight and an observations are taken.

This attachment is used to test the strength of the welds that hold mesh together. The mesh is often used as a reinforcement for concrete structures. as this is a structural component it is essential to test the consistency of the weld in any given section. A joint is cut from the mesh and placed in this attachment. A grip, the HW 14 is then placed on the end of the rod. a force of up to 50 kN is then applied and the shear strength of the weld measured. There is some adjustment in the design with a sliding plate that allows for different gauges of wire. The applicable standards are: BS4483, ASTM A185, ASTM A497 and ASTM A974. The testing application note for this grip is available from the resource area of our School of testing microsite or by clicking here .
