S0281 - Reinforcing Bar Rebend Test to BS4449, BS4482 & BS4483

Image
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.

S274 - Mesh Weld Shear Test

Image
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 .
