Product Code Product Description PRS-ZE0852 CBR Test Machine with Load Ring, 50 kN capacity, 220-240 V 50-60 Hz PRS-ZE0852/110 CBR Test Machine with Load Ring, 50 kN capacity, 110 V 60 Hz STANDARDS NF P94-078; UNI CNR 10009 The PRS-ZE0852 is designed for performing laboratory evaluation of the CBR value of highway sub bases and subgrade and for the determination of strength of cohesive materials which have maximum particle sizes less than 19 mm (3/4â?�). The PRS-ZE0852 is designed to load the penetration piston into the soil sample at a constant rate to measure the applied load and piston penetration at predetermined intervals. The machine is designed to be mounted on a suitable bench and comprises of a robust and compact two column frame with adjustable upper cross beam. The frame has 50 kN capacity. Two test speeds are provided 1.0 mm/min for BS and 1.27 mm/min. for ASTM/EN/AASHTO tests. This main feature allows the user to perform tests complying to BS or ASTM/EN/AASHTO standards with the same machine. Loading and unloading are down from the front panel by UP/DOWN buttons. Unloading speed is udjusted 5 mm/min for easy re-testing. The CBR Test Machine is supplied complete with; â?¢ Load Ring, 50 kN â?¢ Digital Gauge with Connection Part, 25x0.01 mm â?¢ Penetration Piston
